Available Datasets

The available datasets here are still limited to some climate variables. For other data purposes, please contact us.

  1. Topography
    • GTOPO_30 (Global 30 Arc-Second Elevation) | USGS Earth Resources Observation and Science (EROS) Center.

      GTOPO30 is a global digital elevation model (DEM) with a horizontal grid spacing of 30 arc seconds (approximately 1 kilometer) derived from a variety of sources. It was developed over a three year period through a collaborative effort led by staff at the U.S. Geological Survey's Center for Earth Resources Observation and Science (EROS).

    • GMTED_30 (Global Multi-resolution Terrain Elevation Data 30 Arc-second) | USGS Earth Resources Observation and Science (EROS) Center.

      ETOPO is a global relief model of Earth's surface that integrates land topography and ocean bathymetry.

  2. Bathymetry
    • ETOPO_30 | National oceanic and atmospheric administration.

      GTOPO30 is a global digital elevation model (DEM) with a horizontal grid spacing of 30 arc seconds (approximately 1 kilometer) derived from a variety of sources. It was developed over a three year period through a collaborative effort led by staff at the U.S. Geological Survey's Center for Earth Resources Observation and Science (EROS).

  3. Land cover
    • GLCC_30 (Global Land Cover Characterization 30 Arc-second) | USGS Earth Resources Observation and Science (EROS) Center.

      Global Land Cover Characterization (GLCC) is a series of global land cover classification datasets that are based primarily on the unsupervised classification of 1-km AVHRR (Advanced Very High Resolution Radiometer) 10-day NDVI (Normalized Difference Vegetation Index ) composites. The AVHRR source imagery dates from April 1992 through March 1993. Ancillary data sources included digital elevation data, ecoregions interpretation, and country- or regional-level vegetation and land cover maps.

  4. Soil type
    • GLZB_30 (Global Soil Types, 0.5-Degree Grid) | Oak Ridge National Laboratory Distributed Active Archive Center.

      A global data set of soil types is available at 0.5-degree latitude by 0.5-degree longitude resolution. There are 106 soil units, based on Zobler's (1986) assessment of the FAO/UNESCO Soil Map of the World. This data set is a conversion of the Zobler 1-degree resolution version to a 0.5-degree resolution.

  5. Sea surface temperature
    • COBE (Centennial in situ observation based estimates) | Japanese Oceanographic Data Center.

      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. COBE data have been used in the JRA Reanalyses and for AMIP experiments.

    • ERSST v4 (Extended Reconstructed Sea Surface Temperature) | Earth System Research Laboratory NOAA.

      A global monthly SST analysis from 1854 to the present derived from ICOADS data with missing data filled in by statistical methods. The monthly Extended Reconstructed Sea SurfaceTemperature (ERSST) dataset,available on global 2x2 grids, has been revised here in to version 4 (v4) from v3b.

    • Hadley Centre Sea Ice and Sea Surface Temperature data set | Met Office Hadley Centre.

      The SST data are taken from the Met Office Marine Data Bank (MDB), which from 1982 onwards also includes data received through the Global Telecommunications System (GTS). In order to enhance data coverage, monthly median SSTs for 1871-1995 from the Comprehensive Ocean-Atmosphere Data Set (COADS) (now ICOADS) were also used where there were no MDB data.

    • OISST (Optimum Interpolation SST V2) | Earth System Research Laboratory NOAA.

      The NOAA OI.v2 SST monthly fields are derived by a linear interpolation of the weekly optimum interpolation (OI) version 2 fields to daily fields then averaging the daily values over a month. The monthly fields are in the same format and spatial resolution as the weekly fields.

  6. Precipitation
    • TRMM (Tropical Rainfall Measuring Mission) | National Aeronautics and Space Administration.

      Monthly precipitation totals derived from 3B42RT with resolution 0.25 degree. The Tropical Rainfall Measuring Mission (TRMM), a joint mission of NASA and the Japan Aerospace Exploration Agency, was launched in 1997 to study rainfall for weather and climate research. The instruments on TRMM were turned off on April 8, 2015.

    • GPCP (Global Precipitation Climatology Project) | Earth System Research Laboratory NOAA.

      GPCP monthly precipitation dataset from 1979-present combines observations and satellite precipitation data into 2.5°x2.5° global grids.

    • CPC Global Unified Gauge-Based Analysis of Daily Precipitation | NOAA.

      CPC .50x.50 Global Daily Unified Gauge-Based Analysis of Precipitation. This data set is part of products suite from the CPC Unified Precipitation Project that are underway at NOAA Climate Prediction Center (CPC). The primary goal of the project is to create a suite of unified precipitation products with consistent quantity and improved quality by combining all information sources available at CPC and by taking advantage of the optimal interpolation (OI) objective analysis technique.

    • CMAP (CPC Merged Analysis of Precipitation) | NOAA.

      Monthly and pentad global gridded precipitation means. It includes a standard and enhanced version (with NCEP Reanalysis) from 1979 to near the present.

    • GHCN (Global Historical Climatology Network) | provided by ESRL/ NOAA.

      GHCN V2 contains gridded precipitation anomalies calculated from the GHCN version 2 monthly precipitation data set. 2,064 homogeneity adjusted precipitation stations were combined with a data set containing 20,590 raw precipitation stations throughout the world onto a 72x36 (5degx5deg) global grid.

  7. Multi-level data (Air temperature, Zonal wind, Meridional wind, Relative humidity, Geopotential height)
    • 20CR (20th Century Reanalysis) | NOAA-CIRES.

      It contains objectively-analyzed 4-dimensional weather maps and their uncertainty from the late 19th century to 21st century. It covers 2.0 degree latitude x 2.0 degree longitude global grid (180x91).
