Upper Air ReportFebruary 2001

Temperatures in the lowest 8km of the troposphere were 0.04C (.07F) above normal, the 8th warmest February since satellite records began in 1979. Lower tropospheric temperatures in the Southern Hemisphere ranked as the 5th warmest (0.15C, 0.27F above average) while temperatures in the Northern Hemisphere were 0.07C (0.13F) cooler than average. Lower tropospheric temperature data is collected by NOAA's TIROS-N polar-orbiting satellites and adjusted for time-dependent biases by NASA and the Global Hydrology and Climate Center at the University of Alabama in Huntsville.
