STAR Microwave Sounding Calibration and Trends

MSU/AMSU-A/ATMS/SSU Global Mean Layer Temperature Anomaly Time Series

Top three traces: NOAA extended SSU Version 3.0 monthly global mean anomaly time series and trends for layer temperatures of mid-stratosphere (TMS), upper-stratosphere (TUS), and top-stratosphere (TTS). The extension is by merging the NOAA SSU Version 2.0 from 1979-2006 with SSU equivalent channels from AMSU-A/ATMS from 2001 to present. The TMS, TUS, and TTS time series are updated every month. Each update adds the monthly-mean and inter-calibrated SSU equivalent channels from AMSU-A/ATMS from the latest month to the dataset. The pentad and monthly gridded (2.5 latitude by 2.5 longitude resolution) global dataset for NOAA SSU v2.0 can be downloaded from SSU v2.0. The up-to-date, monthly gridded (2.5 latitude by 2.5 longitude resolution) global dataset for the NOAA merged SSU/AMSU-A/ATMS v3.0 can be downloaded from SSU/AMSU-A/ATMS v3.0.

Bottom four traces: NOAA/STAR MSU/AMSU-A/ATMS Version 5.0, monthly global mean anomaly time series and trends for the layer temperatures of lower-troposphere TLT), mid-troposphere (TMT), upper-troposphere (TUT), and lower-stratosphere (TLS). The TLT, TMT, TUT, and TLS time series are updated every month. Each update adds the monthly- mean, inter-calibrated and well-merged AMSU-A/ATMS observations from the latest month to the dataset. The up-to-date, monthly gridded (2.5 latitude by 2.5 longitude resolution) MSU/ASMU-A/ATMS v5.0 data can be downloaded from MSU/ASMU-A/ATMS v5.0.
