## AMSR-E SEA ICE VALIDATION OBJECTIVES

**AMSR-E SEA ICE VALIDATION OBJECTIVES**

** ****To establish retrieval accuracies based on statistical   relationships between AMSR-E sea ice parameters and those same parameters derived from validation data sets covering as many geographical areas as possible for different seasons,**
** ****To understand the limitations of each algorithm including the reasons for their particular level of performance in different regions and for different seasons,**
** ****To suggest improvements to each of the algorithms based on the results of the validation studies.**

## AMSR-E Sea Ice Product Validation:  Field Observations and Modeling Components

**AMSR-E Sea Ice Product Validation:  Field Observations and Modeling Components**

- Coordinated P-3 flights and in-situ measurements (Barrow, AK area. Pilot effort - April 2002; Full campaign - Feb. - March 2003)
-  snow depth and properties on sea ice
-  sea ice and snowpack temperature
-  ice type, thickness, roughness and microphysical properties

- Modeling of the snow-ice-atmosphere column
-  algorithm sensitivities and error under a range of conditions;
-  validation via forward modeling.
