During the Surface Heat Budget of the Arctic Ocean Experiment (SHEBA), measurements of the surface energy budget components were made by NOAA's Environmental Technology Laboratory (ETL), the Cold Regions Research and Engineering Laboratory (CRREL), and the Naval Postgraduate School. These measurements were made at a 20-m central tower and on four 3-m masts at remote sites. The collection of these data throughout the year presented numerous logistical problems. In addition, NOAA/ETL made detailed measurements of the cloud distribution throughout the year using remote sensors. Analyses of these measurements show 1) the annual cycle of conditions at SHEBA, 2) the annual cycle of the surface energy budget, 3) the magnitude of cloud forcing throughout the year, 4) the impact of cloud forcing on the surface fluxes and boundary-layer structure, 5) and the relationship of transitions in the relative magnitudes of surface energy budget terms to synoptic and mesoscale disturbances. This poster will outline the data collection methods and the data processing techniques, and show the annual surface energy budget and cloud forcing. Examples of surface energy budget transitions due to cloud forcing and synoptic/mesoscale forcing will be provided.
