Jeff Angell, researcher at the NOAA Air Resources Laboratory, has put together this briefing on global temperature readings from a 63-station, globally distributed radiosonde network. According to the report based on this network, during 1958-1999, the global, near-surface air temperature warmed by 0.14 degrees C/decade and the tropospheric 850-300 mb layer warmed by 0.10 degrees C/decade, the same as reported for the period 1958-1998 (Angell 1999).
