Thin Ice Area Extraction in the Sea of Okhotsk from Gcom-w1/amsr2 Data
Passive microwave radiometers on-board satellites can penetrate clouds and can monitor the global sea ice distribution on daily basis. The authors have developed an algorithm to extract thin ice area in the Sea of Okhotsk from the passive microwave sensor AMSR2 on-board GCOM-W1 satellite. The algorithm uses the brightness temperature scatter plots of AMSR2 19GHz polarization difference(V–H) vs ...
متن کاملInstrument Performance and Calibration of Amsr-e and Amsr2
The Global Change Observation Mission (GCOM) consists of two satellite observing systems and three generations to achieve global, comprehensive, and long-term Earth monitoring. The first satellite of the GCOM-W (Water) series will be GCOM-W1 with the Advanced Microwave Scanning Radiometer-2 (AMSR2) onboard. AMSR2 is a successor of AMSR on the Advanced Earth Observing Satellite-II (ADEOS-II) and...
متن کاملRetrieving sea surface salinity with multiangular L-band brightness temperatures: Improvement by spatiotemporal averaging
[1] The Soil Moisture and Ocean Salinity (SMOS) mission was selected in May 1999 by the European Space Agency to provide global and frequent soil moisture and sea surface salinity maps. SMOS’ single payload is Microwave Imaging Radiometer by Aperture Synthesis (MIRAS), an L band two-dimensional aperture synthesis interferometric radiometer with multiangular observation capabilities. Most geophy...
متن کاملBuilding a Learning Database for the Neural Network Retrieval of Sea Surface Salinity from SMOS Brightness Temperatures
This article deals with an important aspect of the neural network retrieval of sea surface salinity (SSS) from SMOS brightness temperatures (TBs). The neural network retrieval method is an empirical approach that offers the possibility of being independent from any theoretical emissivity model, during the in-flight phase. A Previous study [1] has proven that this approach is applicable to all p...
متن کاملSea ice thickness retrieval from SMOS brightness temperatures during the Arctic freeze-up period
[1] The Microwave Imaging Radiometer using Aperture Synthesis (MIRAS) on board the European Space Agency’s (ESA) Soil Moisture and Ocean Salinity (SMOS) mission for the first time measures globally Earth’s radiation at a frequency of 1.4 GHz (L-band). It had been hypothesized that L-band radiometry can be used to measure the sea ice thickness due to the large penetration depth in the sea ice me...
