Hello,
I ran WRF v.2.2 for the input produced by WPS-2.2 and for the input
produced by WPS-2.2.1 based on the same GFS GRIB data (20070501_1800_000
and 20070501_1800_006), same compiler, same machine Then I compared the
differences in model output after 6 hours (see below). The last column
rel_RMSE is mine, equal to RMSE/RMS(1). There seem to be great differences
in some fields (for example, W). Are these differences due to improvements
in WPS? Is the output from WPS-2.2.1 supposed to be more accurate?
Best regards,
Jan Ploski
