Remote Sensing of Sea Ice: Retrieval of spectral surface reflection properties from satellite and airborne observations
In order to quantitatively better understand the increased global warming in the Arctic, it is important to assess optical surface properties of the ice covered Arctic Ocean on the global scale from satellite data. Such satellite based retrievals need to be validated against field and airborne observations, taking into account the differences in method, sensors, and observing and atmospheric conditions. The main focus of the research will be to analyze the sources of uncertainties (e.g. different spectral or angular resolution, varying cloud cover, varying surface properties) and use existing radiative transfer models (SCIATRAN, MCARATS) to evaluate the uncertainty when comparing data from satellite sensor and field or airborne campaigns. Such analyses and evaluations have to be done for various measurement methods, surface and atmospheric conditions. For the most common and important sources of uncertainty, an empirical correction can be developed using radiative transfer (RT) models. The task assumes not only running, but also improving the RT models (both models are written in Fortran), and bulk processing of satellite data (suggested to use Python).
