Basic Equations for Flux-Profile Relationships Wind Profile:
• Surface-layer parameters crucial for calculating fluxes of momentum, heat and water vapor in the atmospheric boundary layer (ABL) are derived from vertical profiles of wind velocity, temperature and humidity for the ARM North Slope of Alaska (NSA) site in Barrow. • Parameters include the friction...
