Dear NCL users,
I have a series of daily forecast (in grib2 format) from GFS T574 of
varying hours
the first day forcast has 3 hour intervals (6 files)
the 2nd to 5th day forecast has 6 hour intervals (4 files each day for 4
days = total 16 files)
the 6th day forecast has 12 hour intervals (i.e 2 files)
and the 7th (last) day forecast has 24 hour interval (i.e 1 file)
so total I have 25 forecast file of one day
I am reading all this file together using addfiles and also adding the
extra time dimension using setfileoption
it is working fine with all other variable (viz. wind, temp etc), however
in case of precipitaion the variable name varies in each file so I am not
able to retrieve it
Now I am having following two queries on these data
First Query
1) How to handle same variable with different name in different files so I
can club them all together for further analysis
File Name Variable Name

gfs.t00z.pgrbf06.grb PRATE_4_SFC_ave6h

gfs.t00z.pgrbf144.grb PRATE_4_SFC_ave24h
gfs.t00z.pgrbf168.grb PRATE_4_SFC_ave24h
Second Query
2) How to put time value of irregular interval in the clubbed variable of
all 25 files together
Hope I am clear enough to make you all understand the issues.
Thanks you all in advance.
