California

Using MODIS satellite data, SEBAL was used to compute actual evapotranspiration and the biomass production for the entire state of California for 2002. FREE samples of this coarse-resolution (1000m) data are available below for different time scales. Additionally, high-resolution (30m) data for Kesterson National Wildlife Refuge are available for downloading. These two data samples illustrate the power and flexibility of SEBAL in generating ET data sets with different spatial and temporal scales. This flexibility enables design of cost-effective solutions for virtually all problems where accurate ET mapping is needed.

For users who have no access to Arc/View or Erdas you can download free viewers:

ESRI ArcExplorer^TMGIS viewer for vector and raster data (13MB)
For reference purposes you can download an Arc/View shapefile with the counties of California here
