ds.wx. bin is a weather file. I need to obtain the weather data of a certain longitude and latitude at a certain time. The data format is similar to the above. What should I do?

The codes you're looking for are stored in a table in the "Local Use Section" (section 2) of each grib message. The number in the actual values of the grib message refers to the row in the table that the grid point refers to. Unfortunately, I don't think pygrib supports reading the local use section at all, at least I can't figure out how to do it.

You used to be able to read this section using the "ncepgrib2" module that was included with pygrib, but that's no longer included nor supported.
