Has anyone experienced using WRF with CFSv2 downloaded from RDA? My concern is when we choose WRF-prescribed input, the fields are 6-hourly forecast when our need is the analysis. However, the soil-related fields (i.e. volumetric soil content) are not available in the 'analysis' but they are available in the 6-hourly forecast. Do we need to ungrib different fields from 'analysis' and the 6-hourly forecast for WRF? Is it a good approach to do so? Thank you.
