Instrument 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 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...
متن کاملAMSR-E Algorithm for Snowmelt Onset Detection in Subarctic Heterogeneous Terrain
Snowmelt onset in the upper Yukon River basin, Canada, can be derived from brightness temperatures (Tb) obtained by the Advanced Microwave Scanning Radiometer for EOS (AMSRE) on NASA’s Aqua satellite. This sensor, with a resolution of 14 x 8 km for the 36.5 GHz frequency and two to four observations per day, improves upon the twice-daily coverage and 37 x 28 km spatial resolution of the Special...
متن کاملRecent changes in Antarctic Sea Ice.
In contrast to the Arctic, total sea ice extent (SIE) across the Southern Ocean has increased since the late 1970s, with the annual mean increasing at a rate of 186×10(3) km(2) per decade (1.5% per decade; p<0.01) for 1979-2013. However, this overall increase masks larger regional variations, most notably an increase (decrease) over the Ross (Amundsen-Bellingshausen) Sea. Sea ice variability re...
متن کاملRadiative Feedback Signatures in AMSR - E Sea Surface Temperatures Versus
Radiative feedbacks in the climate system are the primary uncertainty affecting estimates of anthropogenic global warming and climate change (Knutti & Hergerl, 2008; IPCC, 2007). While the feedbacks of most interest are on the long time scales associated with anthropogenic greenhouse gas forcing – decadal or longer – our most accurate satellite measurements of global radiative fluxes are closer...
