Version 3.0 MSU/AMSU - February, 2007

• AMSU data now extends TLT to the present.
• Intersatellite offsets now vary as a function of latitude.
• Data from NOAA-16 AMSU is no longer used.
• NetCDF format now has only 1 time dimension.

Version 3.1 Channel TLT - January, 2008

• TLT 3.1 corrects a processing inconsistency in TLT 3.0: the production code changed between processing AMSU years 1998-2006 and year 2007. For TLT 3.1, all AMSU data have been reprocessed for full version consistency. The effect on TLT decadal trend was minor.
