The AMSU/MSU Midtropo Day/Month Temp Anomalies and Annual Cycle dataset was derived from a series of microwave sounding instruments flown on a series of satellites. Daily Zonal and Monthly Temperature Anomalies for the middle troposphere on a global 2.5 degree grid are derived from both the Advanced Microwave Sounding Unit (AMSU) channel 5, and from the Microwave Sounding Unit (MSU) channel 2 using the Limb 90 correction. The data set is available from January 1978 through present day.
