Soil moisture retrieval from AMSR-E
IEEE Transactions on Geoscience and Remote Sensing, 2003The Advanced Microwave Scanning Radiometer (AMSR-E) on the Earth Observing System (EOS) Aqua satellite was launched on May 4, 2002. The AMSR-E instrument provides a potentially improved soil moisture sensing capability over previous spaceborne radiometers such as the Scanning Multichannel Microwave Radiometer and Special Sensor Microwave/Imager due to ...

IEEE Transactions on Geoscience and Remote Sensing, 2007
The process of determining the geographic latitude and longitude (lat/lon) of the center point of the footprint is called geolocation, which is currently suboptimal for the Advanced Microwave Scanning Radiometer for Earth Observing System (AMSR-E) Level 1 data provided by Japan Aerospace Exploration Agency (JAXA). Here, we present a study for improving

2006 IEEE International Symposium on Geoscience and Remote Sensing, 2006
The Advanced Microwave Scanning Radiometer for the Earth Observing System (AMSR-E) continues to operate nominally on NASA's Aqua satellite. This paper provides a sampling of products from AMSR-E that are of use for a variety of global hydrologic investigations.

AMSR-E and its follow-on, AMSR2
2009 IEEE International Geoscience and Remote Sensing Symposium, 2009The Advanced Microwave Scanning Radiometer for the Earth Observing System (AMSR-E) was built in Japan, and it has been flying on the Aqua satellite since May 2002. Aqua has completed its prime mission in September 2008. The observations from AMSR-E are being used by scientists all over the world in conjunction with other ATrain satellite instruments to

Flexible processing at the AMSR-E SIPS
Proceedings. 2005 IEEE International Geoscience and Remote Sensing Symposium, 2005. IGARSS '05., 2005Processing requirements at NASA's AMSR-E SIPS * have evolved considerably throughout the life span of the mission, as the SIPS has moved from mission testing and early experimental data processing to full operations supporting both forward processing and reprocessing.

Instrument characteristics and calibration of AMSR and AMSR-E
IEEE International Geoscience and Remote Sensing Symposium, 2003The National Space Development Agency of Japan (NASDA) developed two spaceborne microwave radiometers: the Advanced Microwave Scanning Radiometer (AMSR) for NASDA's Advanced Earth Observing Satellite-II (ADEOS-II) and AMSR-E for NASA's Aqua satellite.

Rainfall over land from the AMSR-E
IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004Significant improvements in the retrieval of instantaneous rain rates over land have occurred through the continued evolution of the Goddard Profiling Algorithm (GPROF), which has been used in the TRMM mission and most recently, the Aqua Advanced Microwave Scanning Radiometer (AMSR-E). At present, GPROF V6 incorporates a probability of convective rain,

A soil moisture retrieval method for AMSR-E
IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004For vegetated surfaces, the commonly used soil moisture (SM) retrieval algorithm is a zero-order model which might not be the best one for AMSR-E, since multiple scattering effects could not be ignored at higher frequencies. But due to the simplicity of the zero-order model, it still has the advantage in SM retrieval, except emission relationship ...
