Calls the CDO (Climate Data Operators) sellonlatbox operator with a bounding-box and returns the resulting NetCDF file.cdo sellonlatbox,lon1,lon2,lat1,lat2 in.nc out.nc cdo add/sub/mul/div in1.nc in2.nc out.nc cdo addc,val in.nc out.nc # c= constant, sub etc also of course cdo gec,val in.nc mask.nc # gec = greater-equal constant [gtc,gec,ltc,lec,eqc] cdo fldmean in.nc out.nc # area average cdo timmean in.nc out.nc # time average westpac executive teamRE: command sellonlatbox - Added by Jaison-Thomas Ambadan over 9 years ago. Your input file grid-size/increment is 1.875 degree (see cdo sinfo output) BUT your "sellonlatbox" is less than the increment or grid-size: longitude box is -68.4 to -69.1 is less than 1.875, and latitude as well. so the only possible solution is as suggested by Uwe ... Using cdo - Download the manual from the clima-dods page, or the cdo page. The general form of cdo is cdo command input output e.g. Extract the elds we need: cdo selvar,r ecmwf data.nc rh.nc cdo selvar,cc ecmwf data.nc cc.nc The RH eld has units of percent - we change it to a fraction rst: cdo divc,100 rh.nc rhf.ncDescription R Interface for 'cdo.sellonlatbox' Usage 1 2 3 cdo.sellonlatbox (x, y, ..., dim = c (1, 1), outdir = NULL, outfile = NULL, return.raster = TRUE, parallel = FALSE, npar = NA) Arguments Note This function calls cdo sellonlatbox.CDO is set of 150+ command-line utilities that are extremely helpful for manipulating grib/netcdf file cdo fldmean in. cdo -remapbil,grid1. nc4 uwd_jjason_subtrop.

Merge all netcdf in a folder into single netcdf.In a Bash for loop, all statements between do and done are performed once for every item in a list or number range.; With a big list, use in {list} to loop between a start and end point. Use ellipsis to iterate a full number range, e.g., for number in {1..10}. To skip certain numbers, add a third number to the range. For example, use {0..100..10} to only list every 10th number.cdo timmean -sellonlatbox,lon1,lon2,lat1,lat2 -seldate,date1,date2 in.nc out.nc . where the lon1,lon2 etc define the lon-lat area to cut out and date1,date2 are the date bounds. You can then read the resultant file into R for plotting, or take a quick look with ncview. Tags: R Raster Netcdfelddis motorhome window -fc
