Using machine learning techniques to reconstruct the signal observed by the GRACE mission based on AMSR-E microwave data

open access: yesMiscellanea Geographica: Regional Studies on Development
This study delves into the synergy between remote sensing and satellite gravimetry, focusing on the utilization of Advanced Microwave Scanning Radiometer (AMSR-E) data for modeling delta Total Water Storage (ΔTWS) values derived from the GRACE mission ...

Assimilating MODIS and AMSR-E Snow Observations in a Snow Evolution Model [PDF]

open access: yes, 2012
In this paper four simple computationally inexpensive, direct insertion data assimilation schemes are presented, and evaluated, to assimilate Moderate Resolution Imaging Spectroradiometer (MODIS) snow cover, which is a binary observation, and Advanced ...

A Multitemporal Investigation of AMSR-E C-Band Radio-Frequency Interference [PDF]

open access: yes, 2013
Radio-frequency interference (RFI) is increasingly a severe problem for present and future microwave satellite missions. RFI at C- and X-bands can contaminate remotely sensed measurements, as experienced with the Advanced Microwave Scanning Radiometer ...

Intercalibration of AMSR2 NASA Team 2 Algorithm Sea Ice Concentrations with AMSR-E Slow Rotation Data

open access: yes, 2017
Sea ice estimates from AMSR2 are intercalibrated with AMSR-E fields through a two-step process. First, slow rotation 2 r/min AMSR-E data is used to derive regression equations from colocated pairs of AMSR2 and AMSR-E brightness temperatures (Tb s).

A Nine-Year Climatology of Arctic Sea Ice Lead Orientation and Frequency from AMSR-E

open access: yesRemote Sensing, 2014
We infer the fractional coverage of sea ice leads (as concentration) in the Arctic from Advanced Microwave Scanning Radiometer for Earth Observing System (EOS) (AMSR-E) brightness temperatures.

VALIDATION OF AMSR-E ICE CONCENTRATION & THICKNESS IN THE OKHOTSK SEA

open access: yesGayana (Concepción), 2004
The data from aircraft and ship campaigns in February 2003 in conjunction with high resolution satellite images for validating sea ice concentrations and thickness derived from AMSR-E brightness temperatures are presented. Patrol Vessel "SOYA" conducted time series observations of sea ice parameters such as ice type, floe size, snow thickness, density,
