Dear ferreters
I'm working with a regional climate model, which is defined in
curvilinear coordinates. For the moment I need to interpolate some
globale data on a 1°x1° regular grid onto my curvilinear grid
(0.2°x0.2°). For this purpose I tried the external function
rect_to_curv in ferret (the lon and lat were used from the output of
the regional model). The output I produced was not the one I attended.
I've attached the original data (on the region I am interested in) in
CLM_inerpol2.tiff and the result in CLM_inerpol2.tiff. There is
clearly a problem when the interoplation crosses the 0° meridian. Has
anyone experienced some similar problems with this function and knows
hoa to resolve it?
Any help and suggestion is welcome!
Thanks a lot
Andrew
