GPM DPR Ku Precipitation Profile 2A 1.5 hours 5 km V06 (GPM_2AKu) at GES DISC

Version 06 is the current version of the data set. Older versions will no longer be available and have been superseded by Version 06. .

The 2AKu algorithm provides precipitation estimates from the Ku radar of the Dual-Frequency Precipitation Radar on the core GPM spacecraft. The product contains two swaths of data corresponding to the scans of the Ku radar. The first swath contains matched scans (MS), which are intended to be co-aligned with the Ku-band instantaneous fields of view (IFOV). The second swath contains the high-sensitivity scans (HS), which are interleaved between the Ku/Ku-MS swaths. Both swaths are narrow and centered within the interior of the Ku swath. This is a single-frequency retrieval of precipitation; no information from the Ku radar is used. The retrievals are performed at each radar range bin along the slant path of the radar IFOV for each swath.

This is a single-frequency retrieval that relies on Ku-band data only. While the 2AKu dual-frequency retrieval should give better overall estimates, that algorithm requires co-aligned Ku-band data. This 2AKu product will be produced independently and would not be impacted by any operational issues with the Ku-band radar. The high sensitivity to smaller hydrometeors should result in precipitation estimates in lighter precipitation then the Ku-only data.
