How to estimate precipitable water from surface data?

How can one estimate the water content of the atmosphere from surface data such as temperature, dew point temperature, sea level pressure and relative humidity? (The height of the station is also known.) Thanks your help. Regards MET You can't. You can not calculate exactly, but you can of course estimate it. E.g.: http://ams.allenpress.com/perlserv/?...V%3E2.0.CO%3B2 So estimate the "water content of the atmosphere" and post your answer The paper gives as best fit: W = exp(-0.981 + 0.0341*F) Where W is the water content in cm/m2 and T is the temperature in Farenheit (old paper...) So, for example with T = 50F (283 Kelvin), W is 2.06 cm/m2, and with T = 32F (273 Kelvin), W = 1.12 cm/m2. Sorry, Dew point temperature, of course. |
