Total column water calculation from radiosonde data

  1. Jul 17, 2015 #1
    hello,
    i want to calculate total column water from a radiosonde station data. data are relative humidity, pressure and temperature in various altitude. my course is not physics or meteorology. please help me. is there a free software?

    As your sonde gains altitude, you're going to be sampling a variety of air masses moving in a variety of directions, i.e., generating a meaningless number. Do you have some more specific purpose you can give us?

    I estimate precipitable water vapor with a GPS receiver and i want to Compare with radiosonde PWV.
    I think that i must calculate Precipitable water vapor in the interval of two altitude and then integrate them (in radiosonde data)

    Convert relative humidity to vapor pressure as a function of altitude, and you should get what you're after once you sum/integrate over whatever altitude interval is of interest.
