Due to an error, the Precipitation Processing System will reprocess V04 L1-L3 SSMIS data starting with the last orbit of July 18, 2016. The new files will be recognizable bythe "V04B" in the file name.
An error was introduced into the SSMIS L1 products during a small bug fix in July 2016. The 22V cross-pol correction was unexpectedly turned off and caused the 22V channel Tb to be off by 3 - 6 K.
This error also affected the SSMIS L2 – L3 precipitation products.
Please note that the L2 and L3 Climatology products will also be V04B starting with July 1, 2016.
If you have already obtained any of these V04A products from our archives or through a Standing order, etc., please discard these and use the replacement V04B products.
The following orbital products and related browse files will be replaced with V04B data:
