Sea ice concentration . Sea ice concentration is the fraction of an observational area covered completely by sea ice. Sea ice extent . Sea ice extent represents the total area covered partially or totally by sea ice. For remote sensing applications, a lower threshold of 15 % in the fra...
Simultaneously, the mean annual sea-ice concentration in the southern Lincoln Sea65decreased with −1.4 % per decade (P < 0.001) from 1979–2021 and with −2.7 % per decade (P < 0.001) from 2000 onwards (Fig.3). This is consistent with the observed signs of a changing sea...
Reflection power derived from the global navigation satellite system (GNSS) observations and its sensitivity to sea-ice concentration are investigated in this article. A corresponding experiment has been conducted during the Fram Strait cruise of the Norwegian research vessel Lance in summer 2016. The ...
The proposed new sea-ice concentration retrieval algorithm (SEA LION algorithm) uses the polarization at 85 GHz (). Emission from atmospheric water and scattering at the wind-roughened sea surface (weather effect) decrease and cause an overestimation of the sea-ice concentration. We quantify the ...
A summary of the theoretical basis and initial performance of the algorithms that are used to derive sea ice concentration, ice temperature, and snow depth on sea ice from newly acquired Earth Observing System-Aqua/Advanced Microwave Scanning Radiometer-EOS (AMSR-E) radiances is presented. The al...
Application of a similar filter for use with sea-ice concentration maps derived with the special-sensor microwave imager (SSM/I) sensor is less successful. This results from the position of the 19.35 GHz SSM/I channels, which are closer to the center of the 22.2 GHz atmospheric water-vapor ...
53Altmetric Metrics Abstract Decline in winter sea-ice concentration (SIC) in the Barents-Kara Sea significantly impacts climate through increased heat release to the atmosphere. However, the past Barents-Kara SIC decrease rate is underestimated in the majority of Coupled Model Intercomparison Project ...
A sea ice concentration data set derived from the Nimbus-7 Scanning Multichannel Microwave Radiometer (SMMR) and the Defense Meteorological Satellite Program's (DMSP) DMSP-F8, -F11 and -F13, Special Sensor Microwave/Imager (SSM/I) has been generated using the Bootstrap Algorithm with revised set...
(Supplementary Figure10b). This is expected because the use of the fixed sea-ice concentration (SIC) in the FixedIce run reduces the upward longwave (LW) radiation and sensible and latent heat fluxes (Figs.7,8and Supplementary Figures18,19) and therefore should lead to a larger downward net...
