DatasetsDescription
CMAP Precipitation Monthly and pentad global gridded precipitation means. It includes a standard and enhanced version (with NCEP Reanalysis) from 1979 to near the present.
CPC .25x.25 Daily US Unified Precipitation US high resolution gridded precipitation (from station data) for 1948 to 1998.
CPC Hourly Precipitation NCEP's hourly gridded US station precipitation from 1948.
CPC Soil Moisture Monthly Gridded CPC Soil Moisture from a model from 1948 to present.
CRU Air Temperature and Combined Air Temperature/Marine Anomalies Global gridded (5°x5°) monthly anomalies of combined observed air and marine temperature (HADCRUT2/HADCRUT2V) from the mid 1800's to the present.
CRU Air Temperature and Combined Air Temperature/Marine Anomalies V3 Global gridded (5°x5°) monthly anomalies of observed air temperature and combined observed air and marine temperature (HADCRU3) from the mid 1800's to the present.
Dai Palmer Drought Severity Index Monthly gridded global PDI (Palmer Drought Index) values from 1854-2003 from NCAR.
GISS surface temperature analysis GISS surface temperature analysis for the globe
GPCP V2 Precipitation Global Precipitation Climatology Project monthly precipitation dataset from 1979-present combines observations and satellite precipitation data into 2°x2° global grids.
ICOADS Global surface marine data from 1800 to near the present summarized in monthly gridded formats (2°x2° boxes, or 1°x1° boxes from 1960 forward), and offering a variety of statistics.
Interpolated OLR OLR data from NCAR with sophisticated spatial and temporal interpolation. See the related Uninterpolated OLR dataset.
Kaplan SST Gridded global SST anomalies from 1856-present derived from UK Met Office SST data which has had sophisticated statistical techniques applied to it to fill in gaps.
MSU Two Microwave Sounding Unit tropospheric temperatures and daily average precipitation available in a global grid (2.5°x2.5°).
North American Regional Renalaysis (NARR) NCEP's high resolution combined model and assimilated dataset. It covers 1979 to near present and is provided 8-times daily, daily and monthly on a Northern Hemisphere Lambert Conformal Conic grid for all variables.
NCEP Operational Analysis NCEP's twice-daily global analysis at 2.5° resolution on pressure levels which is a product of their operational forecast system.
NCEP Marine Marine data gathered by NCEP summarized into ICOADS-compatible (2°x2° box) statistics. Updated about 1-5 days following the end of each data month.
NOAA Extended Reconstructed SST A global monthly SST analysis from 1854 to the present derived from ICOADS data with missing data filled in by statistical methods.
NOAA Merged Air and Sea Surface Temperature Monthly Anomalies of air temperature from the GHCN and the NOAAERSST dataset.
NOAA Optimum Interpolation (OI) SST V2 Produced weekly on a 1° grid. The analysis uses in situ and satellite SST's plus SST's simulated by sea-ice cover. Before the analysis is computed, the satellite data is adjusted for biases. Monthly and monthly long-term means are also available.
NCEP Pacific Ocean Analysis Weekly and monthly means for temperature, salinity, u and v velocity components of ocean current at multiple depths. Alos included are weekly and monthly means for a selection of surface flux variables.
NCEP/NCAR Reanalysis A state-of-the-art analysis/forecast system is used to perform data assimilation using data from 1948 to the present.
PSD Derived NCEP/NCAR Reanalysis Products A subset of the NCEP/NCAR Reanalysis has been processed to create monthly means of the original data, and in some cases, derived variables or other statistics.
NCEP/DOE Reanalysis II A state-of-the-art analysis/forecast system is used to perform data assimilation using data from 1979 through 2003. A large subset of this data is available from PSD in its original 4 times daily format and as daily averages.
NOAA Highly Reflective Clouds Subjectively identified areas of large-scale organized convection over the global tropics have been gridded daily for a 15-year period from 1971 to 1988.
NODC (Levitus) World Ocean Atlas 1994 Annual, seasonal and monthly long term means for temperature and salinity at multiple depth. Several statistics such as number of observations are included in separate files.
NODC (Levitus) World Ocean Atlas 1998 The atlas contains annual, seasonal, and monthly long term means for temperature and salinity at multiple depths. Several statistics, including nobs are included in separate files, along with two "mask" files.
Northern Hemisphere EASE-Grid Snow Cover and Sea Ice Extent The NSIDC weekly snowcover and ice dataset has been interpolated to a 1°x1° Northern Hemisphere grid and a monthly time-scale covering 1971 to 1995.
Uninterpolated OLR OLR data from NCEP without interpolation. See the Interpolated OLR dataset for an interpolated version.
U. of Delaware Precipitation and Air Temperature Monthly global gridded high resolution station (land) data for air temperature and precipitation from 1950-1999.
