Generation of
Evapotranspiration Maps
using Landsat Satellite Images
The generation of evapotranspiration maps using Landsat Satellite images is based on METRIC, Mapping EvapoTranspiration at High Resolution and Internalized Calibration, and SEBAL, Surface Energy Balance Algorithm for Land. The SEBAL process has been applied in Asia, Africa, and Europe (SEBAL North America and WaterWatch). This project represents a follow up to one of the first applications in North America. METRIC is an extension to SEBAL for applications in Idaho. More information on the project can be found at the Idaho Department of Water Resources web site, Generation
of Evapotranspiration Maps using Landsat satellite images.
Our activites with the first phase and the second phase of
the project have been highlighted by ERDAS
Inc in their quarterly news letter, ERDAS
News, Vol. 2, No. 4. The first phase was application of the
procedure to the Bear River Basin. The second phase involves appling
the proceedure to the Eastern and Western Snake River plains in
southern Idaho. For more information on the project, please contact
Dr. Richard G. Allen. Some results from METRIC applications in Idaho were presented by Dr. Allen as part of the
2003
ASCE Royce J. Tipton Lecture presented at the USCID-sponsored
Second International Conference on Irrigation and Drainage, May
11, 2003, Phoenix, Arizona.
Additional work on METRIC and other remote sensing techniques for ET over large regions were presented at the
2003 International Workshop on Use of Remote Sensing of Crop Evapotranspiration for Large Regions, in Montpellier, France. For more information on SEBAL and its application in North America, please visit SEBAL North America.
