Greetings: 


I am curious if anyone has experienced issues with the change from RUC to RAP 
with what I was using for 1 hour total precip accumulation from the RUC model. 
As far as I can tell, this parameter was not supposed to change from the 
RUC->RAP transition and should still be present as PxxM (where "xx" is either 
01, 03, 06 or 12). 


Currently, when I run dcgrib2 on files obtained from the NWS TGFTP server ( 
http://weather.noaa.gov/pub/SL.us008001/ST.opnl/MT.rap_CY.12/RD.20120611/PT.grid_DF.gr2/
 ) , I decode nearly all the other precip fields (S01M, C01M, etc) but P01M is 
missing. A portion of the "gdinfo" output is included below:

Any ideas? I have made sure I updated the "g2varsncep1.tbl" and 
"g2varswmo2.tbl" under $GEMTBL/grid from the Gempak tables page. What are we 
supposed to be using
