RSS Version 3.3 Channels TLT, TMT, TTS and TLS – January, 2010
RSS Version 3.2 Channel TLT – November, 2008
RSS Version 3.2 Channels TMT, TTS, and TLS – July, 2008
Changes from 3.2 to 3.3:
- Additional satellites are now included in the merge. Version 3.2 only used data from one AMSU instrument, NOAA-15. For TLT, TMT, and TLS, Version 3.3 includes data from the AMSU instruments on NOAA-15, AQUA, NOAA-18, and METOP-A. AMSU channel 7 exhibits unexplained drifts in METOP-A, so for TTS, data from METOP-A is not used.
- V3.2 is documented thoroughly in “Construction of the Remote Sensing Systems V3.2 atmospheric temperature records from the MSU and AMSU microwave sounders,” Carl A. Mears and Frank J. Wentz, Journal of Atmospheric and Oceanic Technology, 2009, and "Construction of the RSS V3.2 lower tropospheric temperature dataset from the MSU and AMSU microwave sounders," Carl A. Mears and Frank J. Wentz, Journal of Atmospheric and Oceanic Technology, 2009. Version 3.3 is a direct extension of the methods described there.
