Wetlands are one of the most important ecosystems on Earth. There is an urgent need to quantify the biophysical parameters (e.g., plant height, aboveground biomass) and map total remaining areas of wetlands in order to evaluate the ecological status of wetlands. In this study, Environmental Satellite/Advanced Synthetic Aperture Radar (ENVISAT/ASAR) dual-polarization C-band data acquired in 2005...

Remote sensing methods to derive snow properties using both optical and SAR data are presented. The assimilation of the remote sensing products in the water balance and rainfall-runoff model LARSIM is demonstrated. The flood forecast centre in Karlsruhe applies LARSIM for the operational runoff forecast of the Neckar in the South West of Germany. A fully automatic algorithm to derive snow cover...

We describe work conducted to calibrate and then validate the geometry of ENVISAT ASAR products. A systematic error in range location was observed in ASAR products during the commissioning phase. A careful and complete analysis has been performed to establish the precise error. It has been compensated by updating the range gate bias (or sampling window start time bias). Validation of the absolu...

The polarimetric Synthetic Aperture Radar (SAR) data sets have been widely exploited for land use cover (LULC) classification due to their sensitivity the structural and dielectric properties of imaging target. In this study, potential fully L- S-band Airborne SAR (LS-ASAR) were explored machine-learning-based Urban, Vegetation, Waterbody, Open Ground. This work was done by utilizing dual-frequ...

This study presents a new method to analyse some parameters of snow in alpine region: density, wetness. Here are developed the methodology and first results obtained from a set of ASAR-ENVISAT images registered during 2004 spring period over an experimental river basin located in the French Alps (N 45° 05’/ E 6° 10’). For ENVISAT/ASAR data, a topographic processing is done using a Digital Eleva...

RAMSEY, E. III; WERLE, D.; SUZUOKI, Y.; RANGOONWALA, A., and LU, Z., 2012. Limitations and potential of satellite imagery to monitor environmental response to coastal flooding. Journal of Coastal Research, 28(2), 457–476. West Palm Beach (Florida), ISSN 0749-0208. Storm-surge flooding and marsh response throughout the coastal wetlands of Louisiana were mapped using several types of remote sensi...

ENVISAT ASAR is successfully operating since March 2002 and resulting ASAR products are operationally distributed to the user community since December 2002. This paper provides an update of the ASAR performance, from the instrument status to the product quality assessment. 1. ASAR INSTRUMENT STATUS Routine monitoring of the 320 antenna T/R modules is daily performed using Module Stepping Mode (...

Oil spill patterns detected from Envisat ASAR images were integrated with hydrodynamic and oil spill trajectory models for the purposes of understanding the August 11, 2006 M/T Solar 1 oil spill, and to evaluate the accuracy of the oil spill patterns simulated by an oil trajectory model. The oil spill incident event that occurred a few kilometers southwest of Guimaras Island in Panay Gulf and I...
