how to change the resoulation and coordinates?

Added by pooran khedri almost 7 years ago

Dear all,
I have downloaded a netcdf file with below propertie,

:latitude_min = 23.5833339691162 ;
:latitude_max = 30.5 ;
:longitude_min = 47.5 ;
:longitude_max = 57.5 ; longitude:step = 0.08332825f ; latitude:step = 0.08333588f ; latitude = 84 ;
longitude = 121 ;

I want to change the propertis to

:latitude_min = 23.61 ;
:latitude_max = 30.48 ;
:longitude_min = 47.51 ;
:longitude_max = 57.48 ; longitude:step = 0.033333333f ; latitude:step = 0.033333333f ; latitude = 207 ;longitude = 300 ;

I would be grateful if you could help me,
Best ,
Pooran

Hi Pooran,

create a grid description file

e.g. gridfile.txt

gridtype  = lonlat
gridsize  = 62100
xsize     = 300
ysize     = 207
xname     = lon
xlongname = "longitude" 
xunits    = "degrees_east" 
yname     = lat
ylongname = "latitude" 
yunits    = "degrees_north" 
xfirst    = 47.51
xinc      = 0.033333333
yfirst    = 23.61
yinc      = 0.033333333

and use one of the remap operators,

e.g. use bilinear method

cdo remapbil,gridfile.txt infile outfile
