This MSUT2lt 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/DATA402.


Global lower tropospheric 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 troposphere on a global 2.5 degree grid are derived from both the Advanced Microwave Sounding Unit (AMSU), and from the Microwave Sounding Unit (MSU) using the Limb 90 correction. The data set begins on January 1, 1978 and is ongoing.
