AB: For the period of May 2002 to present, as part of the Bay Regional Atmospheric Chemistry Experiment, an observational tower has been maintained in Middle Tampa Bay that is equipped with sensors measuring meteorological and air-water turbulent flux parameters. Data acquired from this tower include air temperature, humidity and horizontal wind velocity measured at two heights, precipitation, incoming radiation, and barometric pressure. A SeaGauge sensor monitors water temperature, salinity, and water level, and a sonic anemometer measures the three-dimensional wind speed and the turbulent flux of momentum and sensible heat. Using data gathered from the tower, sea surface albedo and upwelling and downwelling long- and shortwave radiation fluxes are determined. Heat flux due to precipitation is calculated and the directly measured sensible heat flux is compared with the sensible flux derived using bulk formula and gradient-flux methods. Latent heat flux is also computed via the latter two methods. Temporal and vertical variations, including trends connected with seasonal and shorter signal scale events, are examined. Components of the heat budget of Tampa Bay are determined through a variety of pathways in order to constrain the error associated with the calculation of these parameters.
