PSD Gridded Climate Datasets: Land
| Datasets | Description |
|---|---|
| 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. |
| Interpolated OLR | OLR data from NCAR with sophisticated spatial and temporal interpolation. See the related Uninterpolated OLR dataset. |
| 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. |
| NOAA Merged Air and Sea Surface Temperature | Monthly Anomalies of air temperature from the GHCN and the NOAAERSST dataset. |
| 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. |
| 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. |
