Presentation Transcript

  1. The Surface Energy Balance Algorithm for Land (SEBAL) Remote Sensing of Evapotranspiration

  2. What is MODIS? • Moderate-Resolution Imaging Spectroradiometer • Launched in 1999 aboard the EOS AM (Terra); EOS PM (Aqua) followed in 2002 • Monitors 36 spectral bands between 0.4 m and 14.4 m • Images entire Earth every 1-2 days at 1 km resolution • X data products provided by NASA with full QA/QC

  3. Accessing MODIS Data • Level 1 and Atmosphere Archive and Distribution System (LAADS) • Warehouse Inventory Search Tool (WIST) submits orders via EOS ClearingHouse (ECHO) • Direct access via FTP • HDF files can be manipulated with C, Fortran, Perl, MATLAB, IDL, Mathmatica and now ArcGIS

  4. ET Sensible Heat Flux

  5. Evapotranspiration and Land Use

  6. Validating the Method

  7. ET

  8. SEBAL vs Flux Tower Data

  9. Next Steps • Develop principle for constraining maximum evapotranspiration • Develop principle for estimating net radiation on cloudy days Any Questions?
