Plotting a TRMM NetCDF

Posted on 2023-02-28 by Diego Souza

TRMM NetCDF – Near-Real-Time Precipitation Rate – Plot created with Python

I received the following question:

I saw the Python code examples to plot GOES-R data provided during the 2021 online training course and I would like to create similar plots using TRMM data. I’m trying to reproduce one of the examples and got some errors. Could you please provide an example script to plot this TRMM NetCDF?

Please find below an example script.

These are the steps I followed:

Check the available NetCDF datasets using NASA’s Panoply or using the H5Web extension for Visual Studio Code.
Saw that the precipitation variable is named “TRMM_3B42RT_7_precipitation” and the lat lon bounds are named “lat_bnds” and “lon_bnds”. Also, you may retrieve the time infortation using the “start_time” and “end_time” global attributes.
Created a custom color map using the reference found here.

Installing and Configuring the FAZZT Client on Windows

Posted on 2023-02-14 by Diego Souza

In this procedure we’ll install the KenCast FAZZT Professional Client on Windows, using the files provided by KenCast on the FAZZT DVD. The procedure should work for both FAZZT v9 and v10.

The DVD provided by KenCast (or downloaded via an FTP, also provided by KenCast) has the following content:

In this procedure we’ll use the content from two folders only: “3rdParty/SQLExpress” and “Fazzt/Windows”.

The FAZZT Client needs a database software to work, so in the first step we are going to install the SQL Server 2014.

STEP 1. Access the “3rdParty/SQLExpress” folder and execute the “install64.bat” file. This will install the SQL Server 2014 with the right options (as configured in the “Config64.ini”)

Executing the “.bat” file that will install the SQL Server 2014 with the right options

STEP 5. Let’s configure the FAZZT Professional Client:

KENCAST FAZZT CONFIGURATION

Let’s configure the FAZZT Client for the GNC-A ingestion. The configuration is the same for versions 9.0 or 10.0. At the menu on the left, choose “Configuration” > “Channels” and then, at the “Channels” window, choose “Channels Defaults”. At “Interface”, choose the IP address of the Network Card where you have your DVB-S2 receiver connected – in the example below, 192.168.0.23, the IP of my network card (you may also select the “ALL” option). Click on “Save”.

Selecting the IP of the network card connected to the receiver

Select the ingestion folder at “Configurations” – “Storage Settings” – “Virtual Paths: View/Edit”

Click at the backslash “\” as shown on the image below and choose the folder where the received files will be stored. In this procedure the default location has been shown “C:\Program Files (x86)\KenCast\Fazzt\incoming” but it may be any folder you want. You may use this one or any folder of your preference.

Back to the “Channels” interface, click at the “1.Main” channel “Edit” option:

Chaning the “Main” channel configuration

And at “Interface”, choose “default” (you may also select the “ALL” option).

After a while (a couple of minutes), you should see the GNC-A Broadcast channels being listed at the “Configuration” – “Channels” interface.

Configuring the S300D Receiver on Windows

Posted on 2023-02-14 by Diego Souza

Please find below the procedure to configure the NOVRA S300D, one of the most used DVB-S2 receivers, using both the command line tool (CMCS – Central Management and Control Software) and the Graphical User Interface (NOVRA Mgmt). The procedure below has been tested on Windows 10.

First of all, let’s check the GNC-A downlink parameters:

GNC-A DOWNLINK PARAMETERS

Satellite: Intelsat IS-21 @ 58°W (302°E)
Polarization: Vertical downlink
Transponder: WH 19C
Carrier center freq: 4080 MHz
Symbol rate: 30 Msps
FEC: 5/6
Rolloff: 1.2 (20%)
Format: DVB-S2
PID: 4201

This will be necessary to configure the receiver, especially the “Polarization”, “Carrier center freq”, “Symbol rate”, “Format” and “PID”.

USING THE COMMAND LINE TOOL (CMCS)

STEP 1. Download the CMCS utility from the NOVRA’s webpage:

https://www.novra.com/web/content/4596?unique=7ac42a8e4dc9ddabb3082a83cc17e040a6e09a24&download=true

STEP 2. Unzip the file in the folder of your preference:

STEP 3. Execute the CMCS utility by double clicking the “cmcs300.exe” file. The CMCS Utility will open in a new prompt.

Connect the S300D receiver using a crossover ethernet cable and log on the S300D using the receiver’s IP, as shown in the example below (the IP below is the one from an example receiver. Please confirm the IP of your receiver before trying to connect). The factory IP is 192.168.0.11.

Note: The IP address of the device and the IP address of the workstation network card must reside on the same subnet, or there must be a route that connects both of them through a router.

CMCS> login 192.168.0.11

rface will ask for a password. If you haven’t changed the S300D factory settings, insert the default password: Novra-S2

After that, please execute the following commands:

Note: The “frequency” number on the S300D configuration is the LNB oscilator frequency (5150 MHz) minus the GNC-A downlink frequency (4080 MHz for the new DVB-S2 signal). That’s why the configuration is 1070.

CMCS> mode DVBS2 
CMCS> frequency 1070 
CMCS> symbolrate 30.00 
CMCS> lnb polarization vertical 
CMCS> add pid mpe 4201

The “LOCK” light should turn on if the antenna is correctly pointed towards the satellite and the LNB is correctly set, and the “SIGNAL” light should blink when you have the FAZZT Professional Client already configured and the ingestion begins.

“LOCK” LED on and “DATA” LED blinking, indicating that data is being received

You may check the reception parameters with the “show satellite” or “show sat” command:

CMCS> show satellite

USING A GRAPHICAL USER INTERFACE (NOVRA MGMT)

Using the Novra Mgmt on Windows is very easy.

STEP 1. Download the Receiver Mgt Win32 App V6.3.15 from the NOVRA’s webpage:

https://www.novra.com/web/content/2426?unique=15c195578d6619048454479af62c1812ae653d1c&download=true

STEP 2. Unzip the file in the folder of your preference:

Note: The IP address of the device and the IP address of the workstation network card must reside on the same subnet, or there must be a route that connects both of them through a router.

STEP 3. Execute the Novra Mgmt App by double clicking the “Novra Mgmt V6.3.15.exe” file.

When running the GUI, the receiver should be automatically listed in the “Devices Discovered” window. If not, you can manually add it, inserting the IP and giving it a name (which is optional). Click on “Add”:

The receiver should appear in the “Managed List”. Double click at it:

A window will pop-up, asking for a password. If you haven’t changed the S300D factory settings, insert the default password: Novra-S2

The S300D Management Console will appear. With the factory defaults, you shouldn’t see the signal locked yet.

In the upper toolbat, click on the “Satellite” button.

Click on “LNB Parameters” button, and change the “L.O. Frequency” to 5150. Click OK.

At the “Satellite” window, change the “RF Freq.” to 4080, on “Symbol Rate”, select “Automatic”, check the “LNB Power On?” option, on “Polarization”, select “Vertical / Right” and on “Search Mode”, select “DVB-S2”.

This should be the final configuration for the “Satellite” window. Click “Apply”:

You’ll see a pop-up window saying the new configuration has been successfully applied:

Back to the main window, click at the “Content” button:

In “Add PID > PID” insert “4201” and click “Add”:

The 4201 PID will be added to the list. Click “Apply”. You’ll see a pop-up window saying the new configuration has been successfully applied:

Back to the main window, if the antenna is correctly pointed towards the satellite and the LNB is correctly set, you should see the “Status”, “Signal”, “Data” and “LNB” circles as green and a “Signal Strength” being shown.

Note: The lower the “LDPC BER” the better (bit error rate) and the higher the “Carrier to Noise” the better (a minimum of 10 dB is acceptable. Higher than 12 dB is desirable).

The S300D successfully configured to receive the GNC-A signal

In the receiver, the “LOCK” light should turn on (if the antenna is correctly pointed towards the satellite and the LNB is correctly set), and the “SIGNAL” light should blink when you have the FAZZT Professional Client already configured and the ingestion begins.

Posted on 2023-02-10 by Diego Souza

First of all, let’s check the GNC-A downlink parameters:

GNC-A DOWNLINK PARAMETERS

This will be necessary to configure the receiver, especially the “Polarization”, “Carrier center freq”, “Symbol rate”, “Format” and “PID”.

USING THE COMMAND LINE TOOL (CMCS)

STEP 1. Download the CMCS utility from the NOVRA’s webpage:

https://www.novra.com/web/content/4593?unique=528acf0ed6fd1e4314068cea693989257b9938d0&download=true

or using wget:

wget https://www.novra.com/web/content/4593?unique=528acf0ed6fd1e4314068cea693989257b9938d0&download=true

STEP 2. Decompress the file:

gzip -d cmcs300\ Linux.gz
tar -xvf cmcs300\ Linux

STEP 3. Install the CMCS utility to /usr/bin (so you may use the command anywhere):

install cmcs /usr/bin

STEP 4. Execute the CMCS utility:

cmcs

You will see the following prompt:

Note: The IP address of the device and the IP address of the workstation network card must reside on the same subnet, or there must be a route that connects both of them through a router.

CMCS> login 192.168.0.11

The interface will ask for a password. If you haven’t changed the S300D factory settings, insert the default password: Novra-S2

Connecting to the S300D receiver using CMCS

After that, please execute the following commands:

CMCS> mode DVBS2 
CMCS> frequency 1070 
CMCS> symbolrate 30.00 
CMCS> lnb polarization vertical 
CMCS> add pid mpe 4201

You may check the reception parameters with the “show satellite” or “show sat” command:

CMCS> show satellite

USING A GRAPHICAL USER INTERFACE (NOVRA MGMT)

If you want to use the Novra Mgmt GUI in Linux, we need to use Wine.

Wine is a compatibility layer capable of running Windows applications on several POSIX-compliant operating systems, such as Linux, macOS, & BSD.

STEP 1. Download the Receiver Mgt Win32 App V6.3.15 from the NOVRA’s webpage:

https://novra.com/sites/default/files/resource_pdf/Receiver%20Mgt%20Win32%20App%20V6.3.15.zip

or using wget:

wget https://novra.com/sites/default/files/resource_pdf/Receiver%20Mgt%20Win32%20App%20V6.3.15.zip

STEP 2. Download and install Wine. The Novra GUI is a 32 bit Windows app so we’ll install Wine for 32 bit.

To make things easier, we will download and install wine using the following shell script (right click at “Raw” and “Save link as…”):

https://github.com/zma/usefulscripts/blob/main/script/install-wine-i686-centos7.sh

Change the file permissions:

chmod +x install-wine-i686-centos7.sh

And execute the script:

sh -x install-wine-i686-centos7.sh

After a while, you’ll see the following message:

You may check the installed wine version with the following command (mine is 4.0.1):

wine --version

STEP 3. Executing the Novra Mgmt V6.3.15.exe without a shortcut:

This is not the best way to do but for demonstration purposes, here’s how.

You may use the terminal to execute the app with the following command:

wine /home/dsouza/Downloads/NOVRA/"Novra Mgmt V6.3.15.exe"

Or, you may execute the graphical user interface with wine by right-clicking the “Novra Mgmt V6.3.15.exe” file, and selecting “Open With Other Application”:

Opening the Novra App with wine, manually

And selecting “Wine Windows Program Loader”:

When executing Wine for the first time, it will install some required modules:

Installing the wine dependencies – Gecko

After that, the NOVRA Mgmt GUI will be executed.

However, executing the command on the terminal or right-clicking the “.exe” file might not the most intuitive option, so let’s see how to create a shortcut that will execute the command automatically.

STEP 4. Executing the Novra Mgmt V6.3.15.exe with a shortcut:

First of all, download the following png: Link

Put it in a known directory. We will use it as our shortcut image.

Open a terminal, go to the desktop folder:

cd /home/dsouza/Desktop

Create a desktop file with your favorite editor (gedit in the example below). In this example, we’ll call the shortcut simply “S300D”.

gedit S300D.desktop

Add the following text to the file (note: you need to change where the executable file and the PNG image locations!):

[Desktop Entry]
Version=1.0
Type=Application
Terminal=false
Icon[C]=down
Name[C]=S300D
Exec=wine /home/dsouza/Downloads/NOVRA/"Novra Mgmt V6.3.15.exe"
Name=Novra Management
Icon=/home/dsouza/Downloads/NOVRA/S300D.png

Creating a shortcut that will automatically execute the Novra Mgmt App

Save the shortcut file. Note that the PNG image will not appear yet.

In ther terminal, change the file permissions:

chmod +x S300D.desktop

Also, change the owner to your user name (note: you need to change it to your own username!):

sudo chown dsouza:dsouza /home/dsouza/Desktop/S300D.desktop

When double clicking it for the first time, a pop-up window will appear, saying that the launcher has not been marked as trusted. Click at “Trust and Launch”.

Finishing the shortcut configuration and launching the app

The PNG image configured in the file will appear, and the app will be executed:

Shortcut created, with a custom PNG image

STEP 5. Configuring the receiver using the Novra Mgmt GUI:

Note: The IP address of the device and the IP address of the workstation network card must reside on the same subnet, or there must be a route that connects both of them through a router.

Adding a receiver to the managed list (if not detected automatically)

The receiver should appear in the “Managed List”. Double click at it:

A window will pop-up, asking for a password. If you haven’t changed the S300D factory settings, insert the default password: Novra-S2

The S300D Management Console will appear. With the factory defaults, you shouldn’t see the signal locked yet.

In the upper toolbat, click on the “Satellite” button.

Click on “LNB Parameters” button, and change the “L.O. Frequency” to 5150. Click OK.

This should be the final configuration for the “Satellite” window. Click “Apply”:

You’ll see a pop-up window saying the new configuration has been successfully applied:

Back to the main window, click at the “Content” button:

In “Add PID > PID” insert “4201” and click “Add”:

The 4201 PID will be added to the list. Click “Apply”. You’ll see a pop-up window saying the new configuration has been successfully applied:

Note: The lower the “LDPC BER” the better (bit error rate) and the higher the “Carrier to Noise” the better (a minimum of 10 dB is acceptable. Higher than 12 dB is desirable).
