QuikSCAT backscatter is generally higher over urban areas than surrounding vegetated areas. Azimuthal anisotropy has been observed over some urban areas, but the strength of the azimuthal anisotropy in the urban backscatter signal has not been well quantified. This study investigates radar azimuthal anisotropy in urban areas. QuikSCAT L1B σ observations are compared for urban, non-urban, and un...

RESUME In this work we describe the validation of the land surface temperature (LST) product derived from the Advanced Along-Track Scanning Radiometer (AATSR). A test site was established in a large, flat and homogeneous area of rice crops close to Valencia, Spain. Coincidentally to the Envisat morning overpasses, radiometric temperatures were measured along transects covering the area of one A...

This paper presents analyses of L1B waveforms in SAR mode and Low-Rate Mode (LRM) over water surfaces from numerical simulations from the CryoSat Mission Performance Simulator (CRYMPS) and from CryoSat-2 satellite measurements. This work was performed as part of the ESA project "Development of SAR Altimetry Studies and Applications over Ocean, Coastal zones and Inland waters (SAMOSA)". The proj...

The effects of oxygen supply on growth and carotenoids accumulation by Xanthophyllomyces dendrorhous were studied. Initial volumetric oxygen transfer coefficients (K(L)a) within the range 21.5-148.5 h(-1) had significant effects on growth and carotenoids accumulation, and an increase of the initial K(L)a value led to higher carotenoids, astaxanthin and biomass yields by X. dendrorhous. At an in...

moderate resolution imaging spectroradiometer (modis) have been widely used for active fire detection in the world as the specific channels used for the fire detection have made the modis images applicable. the main objective was to explore the capability of modis images for active fire detection in the zagross forests using the modis contextual algorithm. the study was performed in the marivan...
