Thanks Syed
That is a problem with cdo. The first time step should be considered, the second is just the first timestep of the next month. You should use the average.sh script which is present in the regcm postproc directory, It makes the file with one timestep.average.sh month India_ATM.2002010100_pressure.nc India_ATM.200207.ncOn Thu, May 24, 2012 at 8:11 PM, Kanha Pattnayak <kcpattnayak@gmail.com> wrote:
_______________________________________________Dear AllI am using CDO for calculating daily and monthly files for RegCM4.2 outputs i.e. ATM, RAD and SRF files.After the postprocessing, the monthly files suppose to be of 1 time step but the .ctl files shows 2 time step and both the time steps shows different values.I am totally confuse which time step to use whether 1st or 2nd. Please suggest me what to do.I am using the following command for monthly averageThe following is the corresponding .ctl filedset ^India_ATM.200207.ncdtype netcdfundef -1e+34_FillValuetitle ICTP Regional Climatic model V4 ATM outputpdef 118 99 bilin sequential binary-big ^India.coordxdef 258 linear 49.47 0.24ydef 197 linear -5.11 0.24zdef 11 levels 1000.0 925.0 850.0 700.0 500.0 400.0 300.0 250.0 200.0 150.0 100.0tdef 2 linear 18Z31jul2002 6hrvectorpairs u,v s01u10m,s01v10mvars 14xlon=>xlon 0 y,x Longitude at cross points (degrees_east)xlat=>xlat 0 y,x Latitude at cross points (degrees_north)topo=>topo 0 y,x Domain surface elevation (m)mask=>mask 0 y,x Domain land/ocean mask (1)ps=>ps 0 t,y,x Surface pressure (hPa)u=>u 11 t,z,y,x U component (westerly) of wind (m s-1)v=>v 11 t,z,y,x V component (southerly) of wind (m s-1)omega=>omega 11 t,z,y,x Pressure velocity (hPa s-1)t=>t 11 t,z,y,x Temperature (K)qv=>qv 11 t,z,y,x Water vapor mixing ratio (kg kg-1)qc=>qc 11 t,z,y,x Cloud water mixing ratio (kg kg-1)tpr=>tpr 0 t,y,x Total daily precipitation rate (kg m-2 day-1)tgb=>tgb 0 t,y,x Lower groud temperature (K)swt=>swt 0 t,y,x Total soil water (kg m-2)endvarsThanks in advance--
