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-MMM-YY.
4. OBS_TIME : This column contains the time when the observation was made (end of averaging period), in GMT.
5. DECIMAL_TIME : This column contains the decimal time.
6. NET_RADIATION :
7. SOIL_HEAT_FLUX : This column contains the vertical soil heat flux in the soil ( W m-2 ).
8. SENSIBLE_HEAT_FLUX_1 : This column contains the sensible heat flux from Eddy covariance method ( W m-2 ).
9. LATENT_HEAT_FLUX_1 : This column contains the latent heat flux from Eddy covariance method ( W m-2 ).
10. SENSIBLE_HEAT_FLUX_2 : This column contains the sensible heat flux from gradient method ( W m-2 ).
