HADRT2.2u: Reconstructed gridded data set of global monthly radiosonde temperature anomalies derived from HadRT2.0 (1958-2000)
The HADRT2.2u data are global monthly fields of radiosonde temperature anomalies at standard pressure levels on a 10 degree latitude by 20 degree longitude grid from 1958 to 2000.
Anomalies are calculated with respect to 1971-1990 climatology. Anomalies are available for 9 standard levels (850, 700, 500, 300, 200, 150, 100, 50, 30hPa) as well as tropospheric (850 - 300hPa) and stratospheric (150 - 30hPa) averages.
The data are degree Celsius anomalies from 1970-1990 means. Anomalies are calculated for each of about 200 sonde stations worldwide and grid values derived from these.
HADRT2.2u are as HADRT2.2 but created from HADRT2.0.
This dataset has been superseded by the HadAT dataset also available from CEDA.

|Abstract||HADRT2.2 is an eigenvector reconstructed grid data set from 1958 - 2000, on a 10 degree latitude by 20 degree longitude grid, created from HadRT2.1. The eigenvector reconstruction was used to infill missing seasons or years in boxes with 70% of seasonal or annual data available. HadRT2.1 is in turn based on HadRT2.0 but with bias corrections. That is, anomalies are calculated with respect to 1971-1990 climatology and are calculated for each of about 200 sonde stations worldwide and grid values derived from these and then bias corrections are made to many station time series world-wide. The adjustments were calculated by reference to MSU data products, but only for known changes in instrumental or operational procedures for the period post 1979.|
