Estimate sensible and latent heat fluxes

Description

Returns the sensible and latent heat fluxed based on Zeng et al, 1998'

Usage

calc.zeng(dateTime,Ts,airT,Uz,RH,atm.press,wnd.z,airT.z,RH.z)

Arguments

Ts	numeric value of surface water temperature, degC
airT	numeric value of air temperature, degC
Uz	numeric value of wind speed, m/s
RH	numeric value of relative humidity, %
atm.press	atmospheric pressure in mb
wnd.z	height of wind measurement, m
airT.z	height of air temperature measurement, m (optional)
RH.z	height of relative humidity measurement, m (optional)

Value

A data.frame including sensible and latent heat flux estimates, and other variables used in calculating these fluxes.
