Hello,
Greetings, I want to know how can we calculate the ventilation coefficient, useful in describing boundary layer when we dont have ground based data.


Thanks

hellow johna,
ventilation coefficient is a product of mixing layer height and horizointal wind speed with in the BLH. you can get mixing layer height from HYSPLIT and with the help of any AWS near by your station you can get Wind speed... thats all yours...
