Snow on lake ice: Overview of a multiyear airborne radiometer data collection program and related modeling efforts

We have conducted a multiyear airborne multifrequency microwave radiometer data collection program over a test site comprising two lakes and adjacent land areas in southern Finland. A variety of snow and ice conditions were encountered, covering early winter, mid-winter, and late winter conditions, and the melting season. A semi-empirical radiative transfer forward model has been used for simulations and the theoretical values have been compared with experimental brightness temperature observations.
