متن کاملHow do sea-ice concentrations from operational data compare with passive microwave estimates? Implications for improved model evaluations and forecasting
Passive microwave sensors have produced a 35 year record of sea-ice concentration variability and change. Operational analyses combine a variety of remote-sensing inputs and other sources via manual integration to create high-resolution, accurate charts of ice conditions in support of navigation and operational forecast models. One such product is the daily Multisensor Analyzed Sea Ice Extent (...
متن کاملAntarctic summer sea ice concentration and extent: comparison of ODEN 2006 ship observations, satellite passive microwave and NIC sea ice charts
Antarctic sea ice cover has shown a slight increase (<1%/decade) in overall observed ice extent as derived from satellite mapping from 1979 to 2008, contrary to the decline observed in the Arctic regions. Spatial and temporal variations of the Antarctic sea ice however remain a significant problem to monitor and understand, primarily due to the vastness and remoteness of the region. While satel...
متن کاملAntarctic sea-ice extents and concentrations: comparison of satellite and ship measurements from International Polar Year cruises
Antarctic Sea Ice Processes and Climate (ASPeCt) ship-based ice observations, conducted during the Sea Ice Mass Balance in the Antarctic (SIMBA) and Sea Ice Physics and Ecosystem eXperiment (SIPEX) International Polar Year (IPY) cruises (September–October 2007), are used to validate remote-sensing measurements of ice extent and concentration. Observations include varied sea-ice types at and ins...
متن کاملEnhanced Sea Ice Concentrations from Passive Microwave Data
1. Introduction Sea ice concentration is usually defined as the fraction of ice covered area within an observational field, which in our case is the footprint of the satellite sensor. This assumes that the ocean surface is binary, i.e., either ice covered or ice free. With the binary characterization of the ice covered surface in mind, ice concentration can be quantified from satellite instrume...
