Hi all,
I am learning how to prepare my own atm forcing data. After reading the existing threads on this topic, I still have several questions. First, the TBOT is the temperature at the lowest atm level, which is 30 m in CLM by default. I am wondering what the best observation height should be in my own atm forcing data? If there are air temperatures at 2m and at the lowest model level (about 10m in ERA5), which variable should I use for TBOT? Can I use 10m wind in my forcing data?
I am guessing I can use 2m air temp and 10m wind because some meteorological forcing datasets for land model (e.g. this dataset: Copernicus Climate Data Store | Copernicus Climate Data Store) provide the 2m air temp, 2m humidity, 10m wind, and surface pressure. If I use them to prepare my forcing data, should I also change ZBOT to be 10m or lower? I am not sure where to specify the ZBOT...
Any help is appreciated. Thank you very much!
