Dear Muhammad,

There are quite a few potential reasons for weather file (i.e., IPWTH)
errors.  The "-99" at the beginning of the weather file name normally
indicates a missing value.  I suspect that you either did not enter a
station in the *FIELDS section (under the header, WSTA....), or that its
column position or some other formatting error prevented DSSAT from
identifying it correctly.  I hope this helps.
