Comment:

This Table contains Radiation data.

Principal investigator:

Henk A.R. DE BRUIN

The fields of the table are:

1. GRID_ID : This column contains the name of the grid where the data was taken.
2. GRID_ORDER : This column contains the number of the station in the grid cell.
3. OBS_DATE : This column contains the date on which the observation was made in the format ( DD-MON-YY ).
4. OBS_TIME : This column contains the time on which the observation was made in GMT.
5. DECIMAL_TIME : This column contains the decimal time.
6. GLOBAL_RADIATION : This column contains the shortwave radiation coming from the atmosphere ( W m-2 ).
7. NET_RADIATION_GRASS : This column contains the long and shortwave radiation coming from the atmosphere and the earth surface ( W m-2 ) (grass).
8. NET_RADIATION_BUSHES : This column contains the long and shortwave radiation coming from the atmosphere and the earth surface ( W m-2 ) (bushes + grass).
9. REFLECTED_RADIATION_GRASS : This column contains the shortwave radiation coming from the earth surface ( W m-2 ) (grass).
10. REFLECTED_RADIATION_BUSH : This column contains the shortwave radiation coming from the earth surface ( W m-2 ) (bushes + grass).
11. DIFFUSE_RADIATION : This column contains the shortwave radiation coming from the atmosphere, but scattered by air particles ( not directly from the sun) ( W m-2 ).
12. SURFACE_TEMPERATURE_GRASS : This column contains the surface temperature (grass) ( degrees Celcius ).
13. SURFACE_TEMPERATURE_BAUSH : This column contains the surface temperature (degrees C) (bush).
