Surface temperatures and thickness-derived temperatures from a network of 63 well-distributed radiosonde stations have been used to estimate global and zonal annual and seasonal temperature anomalies for the period 1958 through the 2001. These anomaly estimates were made using a 1958-1977 reference period mean. Anomaly estimates are provided for the surface, troposphere (850-300 mb), tropopause layer (300-100 mb) and low stratosphere (100-50 mb; 100-30 mb) layers for polar, subtropical, and equatorial zones, as well as the tropics, both hemispheres, and the world. Most of the values are column-mean temperatures obtained from the differences in height between constant-pressure surfaces at individual radiosonde stations. The pressure-height data before 1980 were obtained from published values in Monthly Climatic Data of the World.
These temperature anomalies can be used to analyze long-term temperature trends for an atmospheric layer, a region, a hemisphere, or a globe.

Updated methods and trends, including graphics, for Angell's global, hemispheric, and zonal temperature deviations derived from radiosonde records, are also available through CDIAC's Trends Online.
