I have ECMWF ERA-INTERM wind and wave data in GRIB file. how can i extract the data from GRIB file, and how i am using the data GRIB file in MIKE 21 SW model. Please give me your suggestion
Thanks for advance
I am not sure whether MIKE model supports GRIB file, you can just give a try with the GRIB file or try to convert it into ASCII format.
Another suggestion is that you can use the global wind model available in MIKE 21 tool box to generate wind fields.
You can convert GRIB file to the text in MATLAB using NCTOOLBOX. Then you must add some header lines to the text file to be able to convert it to DFS2. The header lines include geographical coordination, number of cells in x & y direction, list of parameters i.e. U, V, MSLP, etc.
Hi, I agree with Mostafa, you can download your data with NetCdf format too.convert them to AscII File which mike 21 can read it. but you have to know about netcdf format . before you put the header lines in your text, you have to extract data correctly. there are (scale factor) and (add_offset) which you have to add them to your data.
MIKE 2016 version supports conversion of netcdf or grib files to dfs2 files directly
MIKE 2016 version supports conversion of netcdf or grib files to dfs2 files directly ===NetCDFClient tool

In case you are still interested, there are now tools from DHI to convert GRIB and NetCDF files into MIKE standard files. You can download them at: https://www.mikepoweredbydhi.com/download/mike-by-dhi-tools
look at DHI mikeio package for any kind of conversion between NetCDF and DFS formats: https://github.com/DHI/mikeio
You can use this library and python to convert the nc files to mike zero dfs2 ASCI and then import to mike zero with dfs2 module and save it as dfs2
