 ||wdir ||horizontal wind direction ||degree || ||
 ||wq ||product of w and q, output of wq_av can be used to calculate the resolved turbulent water flux according to the temporal eddy covariance method by substracting the advective water flux (product of w_av and q_av) from wq_av. ||kg/kg m/s ||requires [[../initialization_parameters#humidity|humidity]] = ''.T.''. Computation of <w'q'> is possible via temporal EC-method, i.e. <w'q'> = <wq> - <w><q>, with < > being the temporal average. For accurate flux calculation the time averaging needs to be sufficiently long (usually 30min) and data from each timestep (choose [[#dt_averaging_input|dt_averaging_input]] small enough) should enter the average to sample also high-frequency flux contributions. ||
