ERA-20C: ECMWF's atmospheric reanalysis of the 20th century (and comparisons with NOAA's 20CR)
Years of record
- to
The ECMWF's first atmospheric reanalysis of the 20th Century, ERA-20C, provides a long, gridded dataset of many climate variables, spanning 1900-2010. Observations assimilated include surface pressures from the International Surface Pressure Databank v3.2.6 and ICOADS v 2.5.1, and surface winds over the oceans from ICOADSv2.5.1. Upper-air and satellite data…

Global surface temperature data: GISTEMP: NASA Goddard Institute for Space Studies (GISS) Surface Temperature Analysis
Years of record
- to
NASA Goddard's Global Surface Temperature Analysis (GISTEMP) combines land surface air temperatures from GHCN-M version 4 with SSTs of the ERSSTv5 analysis into a comprehensive, global surface temperature data set spanning 1880 to the present at monthly resolution, on a 2x2 degree latitude-longitude grid. As such, it is one of the main data sets used to monitor global…

Global surface temperature data: HadCRUT4 and CRUTEM4
Years of record
- to
Extending back to 1850 and frequently updated, HadCRUT4 is the longest data set of its type. HadCRUT4 is a combination of the global land surface temperature data set, CRUTEM4 and the global SST data set, HadSST3. HadCRUT4 is different from the most closely comparable products (e.g. NASA GISTEMP and NOAA MLOST) in that no interpolation is performed. As such, there are…

NOAA's Merged Land-Ocean Surface Temperature Analysis (MLOST) combines land surface air temperatures primarily from the Global Historical Climatology Network, Monthly (GHCN-M) version 3 with SSTs of the ERSSTv3b analysis into a comprehensive global surface temperature data set spanning 1880 to the present at monthly resolution, on a 5x5 degree latitude-longitude grid. As…

Global surface temperatures: BEST: Berkeley Earth Surface Temperatures
Years of record
- to
The Berkeley Earth Surface Temperatures (BEST) are a set of data products, originally a gridded reconstruction of land surface air temperature records spanning 1701-present, and now including an 1850-present merged land-ocean data set that combines the land analysis with an interpolated version of HadSST3. The land station data are available in an archive, and…

GPCC: Global Precipitation Climatology Centre
Years of record
- to
The GPCC provides gridded gauge-analysis products derived from quality controlled station data. Two products are for climate: (a) the Full Data Reanalysis Product (1901-2010) is recommended for global and regional water balance studies, calibration/validation of remote sensing based rainfall estimations and verification of numerical models, and (b) the VASClimO 50-…

GPCP (Monthly): Global Precipitation Climatology Project
Years of record
- to
Data from rain gauge stations, satellites, and sounding observations have been merged to estimate monthly rainfall on a 2.5-degree global grid from 1979 to the present. The careful combination of satellite-based rainfall estimates provides the most complete analysis of rainfall available to date over the global oceans, and adds necessary spatial detail to the rainfall…

NOAA 20th-Century Reanalysis, Version 2 and 2c
Years of record
- to
The Twentieth Century Reanalysis (20CR) provides a comprehensive global atmospheric circulation data set spanning 1850-2014. Its chief motivation is to provide an observational validation data set, with quantified uncertainties, for assessing climate model simulations of the 20th century, with emphasis on the statistics of daily weather. The analyses are generated by…

SST data: COBE: Centennial in situ Observation-Based Estimates
Years of record
- to
The COBE data set is a spatially complete, interpolated 1°x1° SST product for 1891 to present. It combines SSTs from ICOADS release 2.0, the Japanese Kobe collection, and reports from ships and buoys. Data are gridded using optimal interpolation. As in HadISST, data up to 1941 were bias-adjusted using the "bucket correction." Prior to the interpolation analyses, data…

The Hadley Centre Global Sea Ice and Sea Surface Temperature (HadISST) is a combination of monthly globally complete fields of SST and sea ice concentration for 1871-present. This page focuses on the SST data; see the separate page for discussion of HadISST sea ice. HadISST uses reduced space optimal interpolation applied to SSTs from the Marine Data Bank (mainly ship…

SST data: HadSST3
Years of record

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…

SST data: NOAA Extended Reconstruction SSTs, version 3 (ERSSTv3 & 3b)
Years of record
- to
The NOAA Extended Reconstruction Sea Surface Temperature (ERSST) provides global, spatially complete SST data at a monthly timestep for 1854-present. Version3 is based upon statistical interpolation of the ICOADS release 2.4 data. Version 3 includes satellite AVHRR SST data for 1985 onwards. Version 3b does not include satellite data due to a cold bias in the satellite-…
