Accomplishments

Advanced parameterization of broadband sea ice albedo was developed using in situ (SHEBA) data (read more).

Two methods were investigated to estimate melt pond concentrations (read more).

Broadband albedo was systematically estimated from the assimilaton of the AVHRR observations, IABP/POLES SAT, SSM/I brightness temperatures and SSM/I-derived sea ice characteristics (concentration, age, thickness) (read more).

Visible and near-infrared albedos were calculated from the AVHRR observations. Results were validated on SHEBA measurements (read more).

We compared the observed (AVHRR) and modeled (CCSM3) broadband albedo (read more).

Sensitivity analysis of the CCSM3 to uncertainties in albedo parameterization (read more).
