Ku-band radar penetration into snow cover on Arctic sea ice using airborne data
Satellite radar altimetry provides data to monitor winter Arctic sea-ice thickness variability on interannual, basin-wide scales. When using this technique an assumption is made that the peak of the radar return originates from the snow/ice interface. This has been shown to be true in the laboratory for cold, dry snow as is the case on Arctic sea ice during winter. However, this assumption has ...
متن کاملValidation of AMSR Snow Depth on Sea Ice Retrievals Using an Airborne Pulse Radar: Final Report
This is the final report on the project entitled “Validation of AMSR snow depth on sea ice retrievals using an airborne pulse radar.” This is a collaborative project between the Center for Remote Sensing of Ice sheets (CReSIS) at the University of Kansas and NASA Goddard Space Flight Center (GSFC). We designed and developed ultrawideband radars for measuring thickness of snow over sea ice from ...
متن کاملAn Aerocom Assessment of Black Carbon in Arctic Snow and Sea Ice
Though many global aerosols models prognose surface deposition, only a few models have been used to directly simulate the radiative effect from black carbon (BC) deposition to snow and sea ice. Here, we apply aerosol deposition fields from 25 models contributing to two phases of the Aerosol Comparisons between Observations and Models (AeroCom) project to simulate and evaluate within-snow BC con...
متن کاملSnow thickness retrieval over thick Arctic sea ice using SMOS satellite data
The microwave interferometric radiometer of the European Space Agency’s Soil Moisture and Ocean Salinity (SMOS) mission measures at a frequency of 1.4 GHz in the L-band. In contrast to other microwave satellites, low frequency measurements in L-band have a large penetration depth in sea ice and thus contain information on the ice thickness. Previous ice thickness retrievals have neglected a sno...
متن کاملAnalysis of CryoSat’s radar altimeter waveforms over different Arctic sea ice regimes
Satellite altimetry has been used to derive information about sea ice thickness in the Arctic already for several decades. As part of the algorithms applied the shape of the radar signal is used to identify leads, the open water between ice floes. Analysis of airborne altimeter data reveals that the waveform shape can additionally be used to identify different sea ice types. In this study we an...
