Calculate the quasi-steady supersaturation and characteristic relaxation time.
Sqs(W = 1, Nd, T = 5, p = 700)
W |
The updraft [m/s] |
Nd |
A data.frame containing the droplet size distribution with column names "n" and "r" for number concentration and radius. Units can be either SI or /cm^3 and micrometers. |
T |
The temperature in degrees Celsius. |
p |
The pressure is hPa. |
See the equations in Politovich and Cooper (1988) and Cooper (1989) [http://journals.ametsoc.org/doi/pdf/10.1175/1520-0469 [http://journals.ametsoc.org/doi/pdf/10.1175/1520-0469 Given the updraft, droplet size distribution, temperature and pressure, calculates the quasi-steady supersaturation and the associated time constant. Uses a condensation coefficient of 0.04 and an accommodation coefficient of 1.
