AMSR-E/Aqua Monthly L3 5x5 deg Rainfall Accumulations  View Catalog Page Entry ID
AE_RnGd
Summary
The Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) instrument on the NASA EOS Aqua satellite provides global passive microwave measurements of terrestrial, oceanic, and atmospheric variables for the investigation of water and energy cycles.
This Level-3 rainfall accumulation product (AE_RnGd) consists of two grids of 28 rows by 72 columns of monthly averaged rainfall accumulation over ocean and land. Both grids are 5 degree by 5 degree resolution. Monthly ocean rainfall accumulation (mm) is derived from the Wilheit, Kummerow, and Ferraro (1991) algorithm, using Level-2A brightness temperatures as input. Monthly land rainfall accumulation (mm) is derived from the McCollum and Ferraro (2003) algorithm, using Level-2B rainfall data as input. Data are stored in HDF-EOS format, and are available from 19 June 2002 to the present via FTP.

Quality
The investigators perform quality control through visual examination of rainfall products on various temporal and spatial scales to ensure that rainfall maps are consistent with climate records, and that there are no gross errors. They also compare their rainfall estimates with ground-based radar estimates.
