Abstract
The HadAT2 data are global radiosonde gridded temperature anomalies at standard levels (850, 700, 500, 300, 200, 150, 100, 50, and 30hPa) in the troposphere and in the lower stratosphere from 1958 to December 2012. This monthly timeseries are available on a 10 degree longitude by 5 degree latitude basis. This dataset supersedes the HadRT dataset. All values are anomalies relative to the monthly 1966-95 climatology.

Instrument/Platform pairings
| Radiosonde | Deployed on: HadAT radiosonde network |
Computation Element: 1
| Title | HadAT2 Computation |
| Abstract | The HadAT2 data are based on the HadAT1 data (produced by performing quality control and a nearest neighbour analysis on the near raw radiosonde network data of HadAT0) but include an expanded radiosonde network. . See the documentation for full details. |
