The problems I encountered when adding SST ocean temperature data to WRF

[zkk2157]

I want to add SST ocean temperature data in WRF. I downloaded the ocean temperature data of October 5th, 6th and 7th, 2013. The data format is nc. In WPS processing, only grib format data can be processed. Therefore, I want to use the cdo tool to convert the nc format to grib2 format data, but I have been encountering problems. This leads to the failure of conversion. I present the bash script I used for conversion. Thank you for helping me identify the problem.

I would like to ask again. I want to use SST ocean temperature data when simulating typhoons with WRF4.3, but the SST data I downloaded from the official website is in nc format and cannot be used with WPS. Should I convert the SST data from nc format to grib2 format?

I don't think it is necessary to convert netCDF data to GRIB data. You can read SST from your netCDF datafile, then write it to intermediate format datafile.

The format of intermediate file is described in

Chapter 3: WRF Standard Initialization

A sample piece of Fortran code is also provided in the above website.

Please follow the instruction and try. Let me know if you have any issues.
