OA Fortran routines

[lanerolle]

I am interested in using a Fortran-based Objective Analysis (OA) pakage to interpolate and extrapolate scatter data on to a ROMS model grid. I see that under the ROMS webpages, there is an OA package dating back to 1994. Could someone please let me know whether this is indeed the recommended package to be used with ROMS or is there one which is more recent and up to date?

Thanks.

I don't know of anyone still using that package. It has a rather arcane input file format. Many of us are using Manu's Matlab RNT. Anything else people are using?

I have used cdo (Climate Data Operator http://www.mpimet.mpg.de/fileadmin/software/cdo/), which works nicely with netCDF data files. Part of the command suite are different interpolation schemes ( e.g. bilinear, nearest neighbor, conservative remapping .... ). You use cdo directly from your unix command line, which is appealing for me.

However, you might need to adjust your final data files or varinfo.dat to obtain input files, which are accepted by ROMS.
