Impact of Ice Surface and Volume Scatterings on the Microwave Sea Ice Apparent Emissivity

Ice Growth on Sea Surface and Drift of Ice

Sea ice extent from satellite microwave sensors

provide a convenient way to monitor the vast expanses of sea ice in the Polar Regions and this is done primarily using microwave techniques, which contrary to optical instruments, can operate at night and in all-weather conditions. The determination of sea ice extents from satellite platforms can be exploited as a marker for climate change, a navigation tool and a reference for coupled ocean-ic...

MODIS Sea Ice Thickness and Open Water-Sea Ice Charts over the Barents and Kara Seas for Development and Validation of Sea Ice Products from Microwave Sensor Data

We have developed algorithms and procedures for calculating daily sea ice thickness (SIT) and open water–sea ice (OWSI) charts, based on the Moderate Resolution Imaging Spectroradiometer (MODIS), ice surface temperature (IST) (night-time only), and reflectance (R) swath data, respectively. The resolution of the SIT chart is 1 km and that of the OWSI chart is 250 m. The charts are targeted to be...

Uncertainty in modeled Arctic sea ice volume

250 words) 25 Uncertainty in the Pan-arctic Ice Ocean Modeling and Assimilation System (PIOMAS) 26 Arctic sea ice volume record is characterized. A range of observations and approaches, 27 including in-situ ice thickness measurements, ICESat retrieved ice thickness, and model 28 sensitivity studies, yields a conservative estimate for October Arctic ice volume 29 uncertainty of +/1.35x10 km and ...
