SLP anomaly in DJF 1925-26 in ERA-20C
ERA-20C: ECMWF's atmospheric reanalysis of the 20th century (and comparisons with NOAA's 20CR)
Years of Record: 1900/01 to 2011/01
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...

Global surface temperature data: HadCRUT4 and CRUTEM4
Years of Record: 1850/01 to 2018/09
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...

Change of temperature in the Berkeley Earth data Set.
Global surface temperatures: BEST: Berkeley Earth Surface Temperatures
Years of Record: 1701/01 to 2013/03
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...

GPCC: Global Precipitation Climatology Centre
Years of Record: 1891/01 to 2016/12
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...

Map of significant trends in precipitation, according to GPCP v2.2. (contributed by A. Pendergrass)
GPCP (Monthly): Global Precipitation Climatology Project
Years of Record: 1979/01 to 2015/11
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...

NOAA 20th-Century Reanalysis, Version 2 and 2c
Years of Record: 1850/12 to 2014/12
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...

SST data: COBE: Centennial in situ Observation-Based Estimates
Years of Record: 1891/01 to 2018/10
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...

SST data: HadiSST v1.1
Years of Record: 1870/01 to 2018/08
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...

SST data: HadSST3
Years of Record: 1850/01 to 2017/12
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...
