Dear colleagues / Estimados colegas,

Users who have self-implemented GEONETCast stations (including antenna assembly, receiver configuration, and software installation and setup) are coming together for an informal exchange within the user community. / Usuarios que han instalado estaciones GEONETCast desde cero (incluyendo el montaje de la antena, la configuración del receptor y la instalación y puesta en marcha de software) se están reuniendo para un intercambio informal dentro de la comunidad de usuarios.

Experts from Brazil, Uruguay, Mexico, Peru, Argentina, and El Salvador have already joined the group. / Expertos de Brasil, Uruguay, México, Perú, Argentina y El Salvador ya se han unido al grupo.

If you or your team have assembled a station from scratch and would be interested in mutual support within the community, you are very welcome to join! – any language is welcome. / Si usted o su equipo han instalado una estación desde cero y estarían interesados en el apoyo mutuo dentro de la comunidad, ¡serán muy bienvenidos a unirse! – cualquier idioma es bienvenido.

If your organization needs to reactivate its GNC stations (whether self-installed or turnkey solutions) and may benefit from advice, please feel free to share the link below with your technical staff: / Si su organización necesita reactivar sus estaciones GNC (ya sean autoinstaladas o soluciones llave en mano) y podría beneficiarse de asesoramiento, no dude en compartir el enlace a continuación con su personal técnico:

Back in 2022, our colleague William Abarca from MARN El Salvador kindly shared the NHC Tracking and Forecast plots he had implemented on SHOWCast.

These scripts have been shared with the community and other organizations have been able to adapt it. Here’s an example from the Meteorological Department of Curaçao, shared by Haime Pieter:

And here’s an example from Hidromet Mexico, shared by Uriel Crespo:

Thanks for sharing!

This Blog series shows the products developed by the community in the Americas. Most of them refers to data received from GNC-A, however, we also post the development with data received from other means. Please find below the other posts from this series:

New SHOWCast Release: v 2.5.2

A new version of SHOWCast (v2.5.2) is now available on the project’s GitHub repository:

https://github.com/diegormsouza/showcast

This release includes support for GOES-18 and GOES-19, along with various bug fixes and improvements. Additionally, the main interface has received a visual update for a better user experience.

SHOWCast is a processing and visualization tool for GEONETCast-Americas users, providing a basic HTML structure for product selection and animation, and Python scripts to convert satellite data into imagery automatically. SHOWCast can also be used with other satellite reception mechanisms like GRB, Amazon AWS and UNIDATA THREDDS.

Video: Introduction to SHOWCast:

The package runs on both Windows and Linux operational systems. The primary goals for the development of SHOWCast are: Provide a free tool that can be customized (both processing and visualization) and put into operations without the need of having a BIG knowledge in programming and web development (human resources issue) and provide a free tool that can be adapted to the available hardware (technology resources issue).

Demonstration and Community Collaboration:

The old AF products have been discontinued.  We replaced them with new ones using data from all three JPSS satellites.  They are in the “geonetcast/JPSS/PRODUCTS/AF” Folder, Channel 146.

From the product description: From the product description: The eFire system is an integrated system to detect active fires/hot spots by using multiple satellite sensors including VIIRS on S-NPP, NOAA-20 and NOAA-21. The output includes fire pixel locations, fire characteristics, and other metadata fields in NetCDF format.
