Surface soil moisture estimation over the AMMA Sahelian site in 3 Mali using ENVISAT / ASAR data
8 Abstract 9 This paper focuses on different methods for estimating soil moisture in a Sahelian environment by comparing ENVISAT/ASAR and ground data 10 at the same spatial scale. The analysis is restricted to Wide Swath data in order to take advantage of their high temporal repetitivity (about 3–4 days) 11 corresponding to a moderate spatial resolution (150 m). On the one hand, emphasis is put...
متن کاملStudy of Ecosystem Dynamics in Sahelian Floodplains Using Envisat Asar C-band Data
The Waza-Logone floodplain in the north of Cameroon is both ecologically and economically of exceptional importance. Envisat ASAR Alternating Polarization images are used for studying the flooded grassland vegetation. Backscatter signature of different vegetation types, varying in species composition, height, density, and flooding condition, were analyzed and interpreted. Feature selection base...
متن کاملMonitoring Agricultural Activities Using Asar Envisat Data
Space borne radar data facilitates continuous monitoring of almost any location on the earth (limitations in polar zones) with quite low costs. Almost weather-independent operation of radar systems enables a reliable and continuous record of data from earth’s surface. In the framework of an ESA pilot project (AO335), ENVISAT polarimetric SAR data of years 2004 and 2005 are examined for their us...
متن کاملSnow Cover Monitoring Using Multi-temporal Envisat/asar Data
ABSTRACT A method has been developed to apply multi-temporal Advanced Synthetic Aperture Radar (ENVISAT/ASAR, C-Band) images to snow cover monitoring and mapping in mountainous areas. A multi-temporal dataset that includes sequences of ascending and descending ASAR wide swath and beam mode IS2 scenes acquired over Switzerland was investigated. The images were geometrically corrected to remove r...
