Identification of the Properties of the Arcticand Antarctic Ice Cover from the MTVZA-GYaMicrowave Radiometer Data

M. V. Bukharov

Considered is the correspondence between the identification of sea ice properties using the scattering index (SI) computed from the results of measurements accomplished with MTVZA-GYa and AMSU microwave radiometers that register heat radiation at the different angles of incidence. In the framework of the model of the homogeneous ice layer located on the strongly absorbing surface, the difference is specified in the value of the thickness of thin and young ice using the measurements of these radiometers. It is revealed that the minimum values of SI computed from the MTVZA-GYa radiometer data are highly sensitive to the scattering inhomogeneities in the uppermost ice cover layer. Corroborated is the considerable daily variability of SI of the Arctic and Antarctic ice cover that can be an effect of the similar variability of internal stresses and concentration of ice.
