- Abstract
- This datalayer is a point shapefile that shows long-term (1931-1960) mean monthly values for actual evapotranspiration (AE) (in millimeters) on a global terrestrial grid at 0.5 degree longitude/latitude spatial resolution. The dataset is a derived portion of the Global Climate Database (May 15, 1996) which is an updated version of the IIASA database for mean monthly values of temperature, precipitation and cloudiness on a global terrestrial grid (1991), first produced by Rik Leemans and Wolfgang Cramer, and published by the International Institute of Applied Systems Analyses and also distributed by the National Institute of Public Health and Environmental Protection (Netherlands). This version of the datalayer appears as part of the USGS Global GIS : global coverage database (2003). The evapotranspiration scheme used is developed by Prentice et al. Its reference is: Prentice, I.C., Sykes, M. Cramer, W., 1993. A simulation model for the transient effects of climate change on forest landscapes. Ecological Modelling, 65: 51-70. The USGS Global GIS database contains a wealth of USGS and other public domain data, including global coverages of elevation, landcover, seismicity, and resources of minerals and energy at a nominal scale of 1:1 million. The U.S. Geological Survey (USGS) and The American Geological Institute (AGI) announced a cooperative agreement that will focus on making the USGS Global Geographic Information System (GIS) database readily available to educators and the general public in the form of a DVD based world atlas.
- Purpose
- This data is a general purpose global mean actual evapotranspiration datalayer designed to support Geographic Information Systems applications. This layer is intended for researchers, students, and policy makers for reference and mapping purposes, and may be used for basic applications such as viewing, querying, and map output production. This layer will provide a basemap for layers related to socio-economic and political anaylsis, statistical enumeration and analysis, or to support graphical overlays and analysis with other spatial data. More advanced user applications may focus on demographics, urban and rural land use planning and related areas including defining boundaries, managing assets and facilities, integrating attribute databases with geographic features, spatial analysis, and presentation output.

- Data Quality Information
- Attribute Accuracy Report
- The quality has been improved by using stringent station selection criteria for the climatic normal period 1931-1960. The database is now based on c. high-quality 16000-20000 stations world wide. The interpolation methodology has been improved by using a empirical correction scheme with locally derived lapse rates. This scheme works well for both temperature and precipitation.
- Logical Consistency Report
- See process description for IIASA Database (1991).
- Completeness Report
- A global terrestrial 0.5 degree longitude and latitude grid was created. Using the variable 'percentage land' in this data set, terrestrial cells were defined as having at least 60% land. See the process description for IIASA Database (1991) for further details.
