GPM DPR Ku Environment L2A 1.5 hours 5 km V07 (GPM_2AKuENV) at GES DISC
Listed in NASA Data Portal
Version 07 is the current version of the data set.
Description
Older versions will no longer be available and have been superseded by Version 07. . This is environmental data that includes the profiles of atmospheric parameters assumed in the L2 retrieval algorithm.
The 2AKu algorithm provides precipitation estimates from the Ku radar of the Dual-Frequency Precipitation Radar on the core GPM spacecraft. The product contains one swath of data corresponding to the scans of the Ku radar. This is a single-frequency retrieval of precipitation; no information from the Ka radar is used.

The retrievals are performed at each radar range bin along the slant path of the radar IFOV. This is a single-frequency retrieval that relies on Ku-band data only. While the 2ADPR dual-frequency retrieval should give better overall estimates, that algorithm requires co-aligned Ka-band data.
This 2AKu product will be produced independently and would not be impacted by any operational issues with the Ka-band radar.
