Microwave Sounding Unit (MSU) Data

A climatology for each month has been established based on the 10-year period of 1982-1991. A limited number of retrievals during November 1979 and March, April, and August 1981 affected the data and are the reason for the 10-year mean. Monthly anomalies have been formed by subtracting the 10-year mean from the monthly brightness temperatures. The missing data appear to have had a small impact on tropical and summer hemisphere anomalies, but caution should be used when examining the winter hemisphere anomalies during the months of missing retrievals.
