This MSUT4 Version-5 dataset was active from 5 October 1999 to 25 October 2018, and has now been retired.
The new version is now available at http://dx.doi.org/10.5067/GHRC/AMSU-A/DATA401.
Global lower stratospheric temperatures are derived from a series of microwave sounding instruments flown on a series of satellites. Daily Zonal and Monthly Temperature Anomalies for the lower stratosphere on a global 2.5 degree grid are derived from both the Advanced Microwave Sounding Unit (AMSU) channel 9, and from the Microwave Sounding Unit (MSU) channel 4 using the Limb 90 correction. The data set begins on January 1, 1978 and is ongoing.
