selecting shape in Remapping
Added by gabriele greco almost 3 years ago
Hi,
I have a temperature map shaped like a region, but i need to convert the netcfd file from curvilinear coordinates to lon/lat. Since the grid i use for the conversion is rectangular, it gives me as output a wrong shape. is there any way to select in the grid .txt file the exact shape, in order to avoid working with Nan coordinates values? Should i give an array of coordinates in xvals and yvals?
I'll put the wrong grid that i was using.
gridtype = lonlat
gridsize = 1148
xsize = 41
ysize = 28
xname = x
xlongname = "longitude"
xunits = "degrees_east"
yname = y
ylongname = "latitude"
yunits = "degrees_north"
xfirst = 8.48826
xinc = 0.0715
yfirst = 44.63501
yinc = 0.0715

Hi Gabriele,
first, it is always better for regular lonlat grids to use
xname = "lon" yname = "lat"
It is not really possible to say why the interpolation of the region isn't correct. Can you upload the input file?

Hi karin,
we discussed in my previous request. The problem was that the file attached had NaNs in longitude and latitude. I was trying to find a way to select only the area that has real values of longitude and latitude, since the input file is a map with a peculiar shape, in order to do a good remapping with remapbil.
thanks,
Gabriele
