Hi, I want to put the data of the Air´s Temperature, but I didn´t find where. I tried to put it into the data of the river, but it doesn't appears any tab where I can put the temperature.

Can I ask you for what?
If you want to use any rainfall-runoff calculation, they do not need any Air temperature for calculation. Any other reason can be evaporation that you almost have it by ready to use data.
Would you please describe it?

thanks
