Sentences with phrase «= specific humidity»

where L = latent heat of vaporization, ρ = density of air, qs = specific humidity at the surface, qr = specific humidity at a reference height, usually 10m, CDE = empirically measured aerodynamic humidity transfer coefficient (typically around 10 ^ -3 over the ocean), Ur = wind speed at the reference height.

Q = specific humidity (at surface or on one or more atmospheric levels).

Not exact matches

«Height - resolved measurements of specific humidity (q) and relative humidity (RH) are obtained from NASA's satellite - borne Atmospheric Infrared Sounder (AIRS)... The water - vapor feedback implied by these observations is strongly positive, with an average magnitude of λ q = 2.04 W / m2 / K, similar to that simulated by climate models.»

We know R1 + R2 = R = εσT ^ 4 We could use a «bulk equation» for L if we knew the air temperature & specific humidity + wind speed at reference heights.
