arw2arl precision

Post by Smaug » September 2nd, 2019, 6:01 am

Hello,

I have been able to successfully use the arw2arl to convert some wrf outputs. I wanted to know if all the variables in the netCDF files are being used in the dispersion run. I want to ensure that the resolution of the WRF outputs is the same as the resolution of the ARL met. Some notes mention this DIF{W|R} variable but I am not sure how to fully utilise it or how to increase the precision of the variables.

Thanks,

Fantine

There is a technical note for the arw2arl converter: https://www.ready.noaa.gov/data/web/mod ... rw2arl.pdf
You can use the example of WRFDATA.CFG to include DIFR and DIFW for the better precision of precip and vertical velocity.
