The AQUI Soil Moisture Network for Satellite Microwave Remote Sensing Validation in South-Western France

Remote Sensing, 2018
Global soil moisture (SM) products are currently available thanks to microwave remote sensing techniques. Validation of these satellite-based SM products over different vegetation and climate conditions is a crucial step.

Accounting for seasonality in a soil moisture change detection algorithm for ASAR Wide Swath time series [PDF]

, 2012
A change detection algorithm is applied on a three year time series of ASAR Wide Swath images in VV polarization over Calabria, Italy, in order to derive information on temporal soil moisture dynamics.

ASCAT coastal AWDP prototype

, 2008
19 pages, 5 figures, 1 table Local wind fields, such as land-sea breezes and katabatic wind flows strongly affect the weather and microclimate in coastal regions. They determine to a large extent the advection and dispersion of pollutants in the atmosphere and coastal waters (by generation of local wind driven currents).

ASCAT Quality Control near Rain

, 2014
37 pages, 12 figures, 8 tables The Advanced Scatterometer (ASCAT) onboard the Metop satellite series is designed to measure the ocean surfac wind vectors globally. Generally, ASCAT provides wind products at excellent quality. The quality of the Advanced Scatterometer (ASCAT) derived winds is known to be generally degraded with increasing values of the ...

ASAR and ASCAT in Polar Low Situations

Journal of Atmospheric and Oceanic Technology, 2015
AbstractForecasting and monitoring polar lows are, to a large degree, based on satellite observations from passive radiometers and from scatterometer winds in addition to synoptic observations and numerical models. Synthetic aperture radar (SAR) brings higher resolution compared to other remotely sensed sources of ocean wind, such as scatterometer data
