Hi everyone,
I need to use the weather generator (Type 54) to obtain hourly values from monthly data of dry bulb temperature, wind speed, radiation and humidity. I have monthly values of percent relative humidity while Type 54 needs humidity ratio (kg water/kg air). Is there any way around this?
In psychometrics, there is a Type 33e which gives humidity ratio values provided dry bulb temperature and relative humidity. But it needs hourly values of both of these parameters. And I only have monthly values of relative humidity.
Thanks in advance.
