CDO

Hi,

I'm trying to interpolate some data from a lat-lon projection to a Lambert Conformal Conic (lcc) projection. I'm using the command:

cdo -f grb remapbil,gridSAlcc3.txt -setgrid,grideraiNorthInv.txt erai_geoYlandsea_SA_inv.grib erai_geoYlandsea_SA_lcc.grib

where gridSAlcc3.txt is:

1. gridID 0 #
   gridtype = lcc
   gridsize = 7990
   xsize = 85
   ysize = 94
   originLon = -90.0
   originLat = 0.0
   lonParY = -60
   lat1 = 5
   lat2 = 42
   xinc = 91202.7
   yinc = 91202.7
   projection = north

and grideraiNorthInv.txt is:

1. gridID 0 #
   gridtype = lonlat
   gridsize = 7938
   xname = longitude
   xlongname = longitude
   xunits = degrees_east
   yname = latitude
   ylongname = latitude
   yunits = degrees_north
   xsize = 81
   ysize = 98
   xfirst = -90
   xinc = 0.75
   yfirst = -57.75
   yinc = 0.75

My input data covers latitudes on both hemispheres. My problem is that the output file only contains data for the northern hemisphere: all the data south of the equator is lost. I also tried by setting "projection = southpole" for the target grid, but the result is the same as before.
How can I get the right transformation? I'm attaching my working files. I will appreciate any comments on this issue.

Best regards,

John
