Hi!

I noticed that there are 9 options for the method of vertical motion (input model data, isobaric, isentropic...). And the result will be very different with different options. Any one can tell me the principle to choose the method?

Many thanks in advance!

BTW, this forum is wonderful for users!

Happy new year!

Unless you have a reason to choose otherwise you should use the meteorological model vertical velocity output. Nevertheless, depending on your particular application you might need to choose a different option.

Thanks a lot for reply!
