-**Q. Pcp-Combine - What data formats does MET read?**
-
-A. 
-MET can read gridded data in GRIB1, GRIB2, or 3 different flavors of NetCDF: 
-
-* The "internal" NetCDF format that looks like the output of the
-  pcp_combine tool. 
-* CF-compliant NetCDF3 files. 
-* The output of the wrf_interp utility.
-
-If there is NetCDF output from WRF, use UPP to post-process it.
-It does not need to be "lat-lon". It can be post-processed to whatever
-projection is needed.
-
-There is in general no easy way to convert NetCDF to GRIB. If the NetCDF
-data is self generated, make it look like the NetCDF output from
-pcp_combine, or preferably, make it CF-compliant.
-
-Looking at the accumulation interval of the precipitation data in the WRF
-output files from UPP, use the "wgrib" utility to dump out that sort
-of information:
-
-.. code-block:: none
-
-		wgrib wrfprs_d01.02 
-		wgrib wrfprs_d01.03 
-
-and so on.
-
-The question is whether the output actually contains 1-hourly accumulated
-precip, or does it contain runtime accumulation. Runtime accumulation
-means that the 6-hour wrf file contains 0 to 6 hours of precip; the
-7- hour file contains 0 to 7 hours of precip; and so on. The precip
-values just accumulate over the course of the entire model integration.
-
-The default for WRF-ARW is runtime accumulation. So if WRF-ARW is running
-and the output bucket interval wasn’t specifically changed, then that's
-very likely.
-
-If that is the case, you can change these values to interval accumulations.
-Use the pcp_combine "-subtract" option instead of "-sum". Suppose the
-6 hours of precip between the 6hr and 12hr forecasts is wanted. Run the
-following:
-
-.. code-block:: none
-
-		pcp_combine -subtract wrfprs_d01.12 12 \
-		wrfprs_d01.06 06 apcp_06_to_12.nc
-
-This call to pcp_combine gets 12 hours of precip from the first file and 6 hours
-from the second file and subtract them.
