Targetgrid, latitude
Added by E. Santiago Gonzalez almost 11 years ago
Hi,
When I use the operator:
cdo -f grb -random,r<xsize>x<ysize> template.grb
The latitudes are:
for ysize= 180; yinc= 1; yfirst= -89.5, y=-89.5, -88.5, -87.5, ...
for ysize= 360; yinc= 0.5; yfirst= -89.75; y=-89.75, -89.25, -88.75, ..
e.g.
cdo -f grb -random,r720x360 template.grb
griddes template.grb:
# gridID 2 # gridtype = lonlat gridsize = 259200 xname = lon xlongname = longitude xunits = degrees_east yname = lat ylongname = latitude yunits = degrees_north xsize = 720 ysize = 360 xfirst = 0 xinc = 0.5 yfirst = -89.75 yinc = 0.5
But, I would like that the first latitude was -90º.
How I can achieve that, any help will be appreciable.
Thank

You have to define you own grid. Here is an example:
cat > mygrid << EOR gridtype = lonlat xsize = 720 ysize = 360 xfirst = 0 xinc = 0.5 yfirst = -90 yinc = 0.5 EOR cdo -f grb -random,mygrid template.grb
