There are many methods of measuring the moisture content of air. When data sets are combined, it is likely that several methods have been used. In most boundary layer applications, these measurements must be converted to specific humidity. This routine converts all the common humidity measurements to specific humidity.
find_q Input
| Parameter | Type | Description | Units |
| moist_prm | int | option for humidity observation units | none |
| moist_val | float | value of humidity observations | variable |
| press | float | atmospheric pressure | Pa |
| temperature | float | temperature of air | oC |
Options for Input Humidity (moist_prm)
Choose the moisture parameter that is easiest for you to deal
with:
| moist_prm | Parameter for moisture (moist_val) | Units |
| Specific humidity | g vapor / g air | |
| Relative humidity | fraction | |
| Dew point temperature | C | |
| Wet bulb temperature | C |
find_q Output
The function returns specific humidity in units of kg kg-1.
