From Radiosonde data, we have RH (with respect to water?), temperature, pressure, etc. If we want to convert RH with respect to liquid water to RH with respect to ice, what is the simple way to do it?
Thanks Prof. Vincenzo. Suppose that we use modified Goff and Grach equation to estimate the saturation vapor pressure with respect to water and with respect to ice. Then estimate RH with respect to ICE for the levels above freezing point. Some equation can be found here: https://www.eas.ualberta.ca/jdwilson/EAS372_13/Vomel_CIRES_satvpformulae.html Is it acceptable in this way?
