Note: Beginning in December 2010, all lower troposphere, middle troposphere, and lower stratosphere satellite data are reported here with respect to the 1981–2010 base period. Prior to December 2010, data were reported with respect to the 1979–1998 base period. Remote Sensing Systems continues to provide data to NCEI with respect to the 1979–1998 base period; however, NCEI readjusts the data to the 1981–2010 base period so that the satellite measurements are comparable.
