+ | ==== No Data Flag ==== | ||
+ | |||
+ | In all ENVI-met output files, the value of **-999** represents the "No Data" flag. Why certain grids do not carry valid data depends mainly on the data itself and how it was generated, so no general explanation can be given here. In any case, data flagged with a "No Data" value should not be included in any further data analysis or visualisation. | ||
