[gradsusr] relative humidity

[Rowell, Mason D.]

Hello,

Use your actual specific humidity and divide by the saturation specific humidity (multiply by 100%). This should be accurate enough, though you should use mixing ratio in place of specific humidity for both. Saturation specific humidity is ~ .622*es/p, with es given by the integrated CC equation (which will depend on temperature only) and p the atmospheric pressure at the level of interest. That shouldn't be too hard to code.

Dear all,

Does someone have a script or knew a way to calculate the relative humidity from specific humidity?

Regards
