Improvements in the estimates of ice thickness and production in the Chukchi Sea polynyas derived from AMSR-E
[1] For January–March 2003, we use 12.5-km resolution Advanced Microwave Scanning Radiometer (AMSR) data for the first time in a comparison with Synthetic Aperture Radar (SAR) and Special SensorMicrowave/Imager (SSM/I) data to study two Chukchi coast polynyas, one consisting of many, the other of only a few 25-km SSM/I pixels. Within these polynyas, the ice thicknesses are derived separately fr...
متن کاملIce production and salt rejection of Laptev Sea polynyas,using model and remote sensing data
The Laptev Sea polynyas in the Siberian Arctic are well recognized as strong ice producers [1, 2] and may play a critical role with regards to sea ice volume changes in the Arctic. These flaw polynyas were studied during two seasonal cycles (2007 – 2009) by the Russian-German research project “Laptev Sea System” [3]. A focus was set on an investigation of the contribution of the West New Siberi...
متن کاملSea ice production and export from coastal polynyas in the Weddell and Ross Seas
[1] For 1992–2008, we use data from the Special Sensor Microwave/Imager (SSM/I) and the Advanced Microwave Scanning Radiometer‐EOS (AMSR‐E) to examine differences in ice production and export in the Weddell and Ross Seas. We find that the Ross production is three times that in the Weddell; the Ross export, twice that in the Weddell. In the Ross, the ice production has a statistically significan...
متن کاملAn assessment of sea ice thickness calculated from AMSR-E and MODIS for operational data assimilation
In this paper, sea ice thickness values are calculated for a region along the east coast of Canada using data from two sensors representative of those available for operational data assimilation. Data from the first sensor, the Moderate Resolution Imaging Spectroradiometer (MODIS), is used to calculate the ice thickness using a heat balance equation. Relationships between the MODIS ice thicknes...
متن کاملA global satellite environmental data record derived from AMSR-E and AMSR2 microwave Earth observations
Spaceborne microwave remote sensing is widely used to monitor global environmental changes for understanding hydrological, ecological, and climate processes. A new global land parameter data record (LPDR) was generated using similar calibrated, multifrequency brightness temperature (Tb) retrievals from the Advanced Microwave Scanning Radiometer for EOS (AMSR-E) and the Advanced Microwave Scanni...
