Dear Colleagues…

We are happy to let you know that we have added more geospatial climate datasets to the CGIAR-CSI GeoPortal:

  1. CGIAR-CSI GLOBAL-PET and GLOBAL-ARIDITY GeoSpatial Database The Global Potential Evapo-Transpiration (Global-PET) and Global Aridity Index (Global-Aridity) datasets provide high-resolution global raster climate data related to evapo-transpiration processes and rainfall deficit for potential vegetative growth. These datasets are based on modeling and analyses by Antonio Trabucco (currently at the Forest, Ecology and Management Research Group, K.U. Leuven), with the support of theInternational Water Management Institute (IWMI) and the International Centre for Integrated Mountain Development (ICIMOD), and are provided online by the CGIAR-CSI Consortium for Spatial Information with the support of the International Center for Tropical Agriculture (CIAT). The Global-PET and Global-Aridity datasets are provided for non-commercial use in standard ARC/INFO Grid format, at 30 arc seconds (~ 1km at equator), to support studies contributing to sustainable development, biodiversity and environmental conservation, poverty alleviation, and adaption to climate change globally, and in particular in developing countries.
  2. The CRU TS 2.1 Climate Database: Reformatted for GIS Spatial Analysis This database is now back on-line and available for download (was unavailable for awhile due to server crash)
  3. The CDM-AR Forest Definition On-Line Analysis Tool: Now back on line, and functioning (was unavailable for awhile due to server crash) Many thanks to Antonio Trabucco, Sadir Mohammed, Andy Jarvis (and me, who spent my weekend on this!!!)

Best regards,
Robert (
