Browse Only Airborne Second Generation Precipitation Radar (APR-2) TC4
Listed in NASA Earthdata CMR
The Airborne Second Generation Precipitation Radar (APR-2) dataset is a dual-frequency (13 GHz and 35 GHz), Doppler, dual-polarization radar system.
Description
It has a downward looking antenna that performs cross track scans. Additional features include: simultaneous dual-frequency, matched beam operation at 13.4 and 35.6 GHz (same as GPM Dual-Frequency Precipitation Radar), simultaneous measurement of both like- and cross-polarized signals at both frequencies, Doppler operation, and real-time pulse compression (calibrated reflectivity data can be produced for large areas in the field during flight, if necessary).
The APR-2 flew on the NASA DC-8. NOTE: This is a browse only dataset in .jpg format. The images are from June 28, 2007 through August 5, 2007.
