A Bulk Turbulent Flux Algorithm for Sea Ice, Based on the SHEBA Data Set

The SHEBA data fell into only two aerodynamic seasons: winter, when the sea ice was compact and snow-covered and the snow was dry enough to blow and drift; and summer, when the snow was wet and sticky and eventually disappeared and the surface was finally covered by both ice and open water in melt ponds and leads. We also found that summer sea ice behaves, aerodynamically, like the marginal ice zone. This algorithm, therefore, provides estimates of the surface stress and the sensible and latent heat fluxes over winter sea ice, over summer sea ice, and over marginal ice zones in any season. Using an analysis of data from Ice Station Weddell, this new version of the code also allows you to specify a physical roughness of the sea ice (xi) if you have an estimate of that quantity. This version of the algorithm, therefore, has three options for representing the aerodynamic roughness.
