SST data: HadSST3
Years of record
- to
HadSST3 provides monthly SST anomalies on a 5°x5° grid for 1850-present. The anomalies are derived from a 30-year climatology spanning 1961-90.Coverage is global but there is no interpolation; Thus, missing data occur in the final product. The primary input data are from ICOADS release 2.5. Bias adjustments to the ICOADS SSTs account for changes in measurement methods (e…

HadSST4 provides monthly SST anomalies on a 5°x5° grid for 1850-present. The anomalies are derived from a 30-year climatology spanning 1961-90. Coverage is global but there is no interpolation; Thus, missing data occur in the final product. This means that uncertainties due to limited spatial coverage and systematic errors are relatively easy to identify compared with…

Standardized Precipitation Evapotranspiration Index (SPEI)
Years of record

The Standardized Precipitation Evapotranspiration Index (SPEI) is an extension of the widely used Standardized Precipitation Index (SPI). The SPEI is designed to take into account both precipitation and potential evapotranspiration (PET) in determining drought. Thus, unlike the SPI, the SPEI captures the main impact of increased temperatures on water demand. Like the SPI…

This is a monthly, zonal-mean ozone profile data set spanning 1979–2005 for altitudes from the tropopause up to 50 km. Interannual variability is based on a combination of SAGE (Stratospheric Aerosol and Gas Experiment) satellite profile measurements and polar ozonesondes. The interannual anomalies were added to a climatology from Fortuin and Kelder (1998). …
