AMSR-E/Aqua L2B Global Swath Surface Precipitation GSFC Profiling Algorithm, Version 4

The AMSR-E/Aqua Level-2B precipitation product includes instantaneous surface precipitation rate and type over ice-free/snow-free land and ocean between 89.24 degrees north and south latitudes at at 10 km spatial resolution along the track and 5 km spatial resolution along the scan. The data are generated by the GPROF 2017 algorithm using Version 4 of the AMSR-E Level-2A Brightness Temperatures.

This is the most recent version of these data.

FAQ

Why does the number of pixels per scan vary among different Level-2 AMSR-E data sets?
A typical AMSR-E swath width consists of approximately 2000 scans, with 243 pixels per scan for the 6.9 GHz to 36.5 GHz channels, and 486 pixels per scan for the 89.0 GHz channel. In 2002, the AMSR-E science team discovered distortion along the outer 23 to 24 pixels of each swath. Some algorithm... read more
