Combining information derived from satellite-based passive and active microwave sensors has the potential to offer improved estimates of surface soil moisture at global scale. We develop and evaluate ...
This paper presents a comparison and an evaluation of five soil moisture products based on satellite-based passive and active microwave measurements. Products are evaluated for 2005–2006 against groun...
Microwave signatures have been found to, be related to variations in snow conditions found on the earth's surface. Most of these observations have been obtained by passive microwave radiometry. In g...
Ground thawing and soil warming arc governed by ground heat flux, soil thermal properties and the ice content of the soil, all of which are directly or indircctly inlluenced by the soil moisture sta...
Synthetic aperture radar (SAR) has the potential for measuring near surface soil moisture contents for very largc areas. The polar orbiting European Remote Sensing satellitc (ERS-I) of the European ...
The launch of the European Remote sensing Satellite (ERS-1) in July 1991 represented an important turning point in the development of Earth observation as it was the first of a series of satellites wh...
