The objective of this research is to identify the proper polarization to avoid certain effects of rain attenuation in the Off-the-Grid (OTG) single polarized X-band radar network installed in the western region of the tropical island of Puerto Rico. This network was developed under the NSF CASA-ERC1
at UPRM2.
To achieve this, it was necessary to have two independent
OTG radars with different orthogonal polarizations. Then a
comparison between horizontal polarized data and vertical
polarized data was performed to calculate the differential
reflectivity (Z ). The results will be presented along this paper.
developed an Off-The-Grid (OTG) X-band single polarized radar network deployed in the Puerto Rico west coast.
With this kind of radar it is possible to observe some meteorological events that might not be detected by NEXRAD
radar due to earth curvature. The main goal of this research is to break with the paradigm and limitations of using X-
band OTG radars as a reliable forecast system, where the principal issue is the attenuation due to rain along the
path. To overcome this problem the attenuated signal could be rectified through a correction algorithm based on
reflectivity and also an ideal polarization (vertical or horizontal) will be identified to certain effects of rain attenuation.
To correct for attenuation a hybrid between Hitschfeld – Bordan (HB) method and a Surface Reference Technique
(SRT) would be used where the reference signal is the NEXRAD radar data because is considered negligible to
attenuation.
