Processor Description - SEBS

Please note: The chapter BEAM Scientific Data Processors provides a general description for all BEAM data processors. It describes the common graphical user interface (GUI), the command-line interface and the common processing request file format.

The SEBS In- and Output Parameter tab

1. Reference height : Reference height in meters.
2. Humidity: Specific humidity at reference height in kg per kg.
3. Wind speed: Wind speed at reference height in meters per second.
4. Temperature: Air temperature at reference height in degrees C.
5. Pressure: Air pressure at reference height in Pa.
6. Pressure at surface: Surface air pressure in Pa.
7. BPL height: Height of the Planetary Boundary Layer (PBL) in meters.
8. Horizontal visibility: Horizontal visibility.
9. Solar radiation: Select this option by typing in a value for downward shortwave radiation in Watt/m^2 that will be applied to all pixels. Unselect the option if you wish the routine in SEBS to calculate a value for downward shortwave radiation using the elevation data.
10. Input AATSR file: Select the input product file by either typing the product path into the text field or pressing the file selection item to invoke a standard file dialog. This input product must contain bands named btemp_nadir_1200 and btemp_nadir_1100
11. Input SMAC file: Select the input product file by either typing the product path into the text field or pressing the file selection item to invoke a standard file dialog. This input product must contain bands named reflec_nadir_0870 and reflec_nadir_0670. These bands must be atmospherically corrected (use the SMAC processor on the AATSR product)
12. Land use file: Select this option when you wish to use land use classes and associated vegetation height values on the estimation of the sensible heat fluxes. This input product must contain a band named land_use_class. You can type values into the text fields to change the vegetation height via Landuse Parameters Tab.
13. Leaf area index file: Select the option to select the input product file for leaf area index. This input product must contain a band named leaf_area_index.
14. Output product file: Select the output product file by either typing the product path into the text field or pressing the file selection item to invoke a standard file dialog.
15. Output product format: Select one of the available output product formats from the combo box.

The SEBS processing request file

The following table describes the SEBS specific processing request file parameters. For a detailed description of the processing request file concept and file specification please take a look at the section general description inside the chapter BEAM Scientific Data Processors described at the top of this page.
