In order to complement present water quality monitoring of large lakes, we have attempted to make use of satellite imagery. In addition to ocean color sensors SeaWiFS and MODIS, lately MERIS images also became available. Here we analyze 18 almost cloud free full resolution atmospherically corrected MERIS images over the large European lakes Vättern, Vänern and Peipsi, where water type ranges fr...

It is a fact that Mediterranean Europe suffers severe wildfire events, as it occurred in summer 2003. The Valencia de Alcántara fire that took place near the border between Portugal and Spain, was one of the mentioned events. The present paper tries to evaluate how reliable are burnt area estimations made from medium resolution satellite images, processed and delivered in near real time. In ord...

Monitoring river water quality with satellite data has been limited by the lack of sensors offering high revisit frequency and suitable spatial and radiometric resolutions. In this communcation, it is shown that the last generation of moderate resolution sensors makes possible to monitor efficiently large tropical basins characterized by reduced field monitoring and strong cloud coverage. Empha...

The 3 km Dark Target (DT) aerosol optical depth (AOD) products, 10 km DT and Deep Blue (DB) AOD products from the Collection 6 (C6) product data of Moderate Resolution Imaging Spectroradiometer (MODIS) are compared with Sun-sky Radiometer Network (SONET) measurements at Song Mountain in central China, where ground-based remote sensing measurements of aerosol properties are still very limited. T...

Relation between chlorophyll-a concentration and red tide in the intensive study area of the back of Ariake Sea, Japan in the recent winter seasons is investigated by using MODIS data. Mechanism of red tide appearance is not so clarified. On the other hand, chlorophyll-a concentration can be estimated with satellite remote sensing data. An attempt is made for estimation of the location and size...

[1] The February 2001 eruption of Cleveland Volcano, Alaska allowed for comparisons of volcanic ash detection using two-band thermal infrared (10–12 mm) remote sensing from MODIS, AVHRR, and GOES 10. Results show that high latitude GOES volcanic cloud sensing the range of about 50 to 65 N is significantly enhanced. For the Cleveland volcanic clouds the MODIS and AVHRR data have zenith angles 6–...

The Moderate Resolution Imaging Spectroradiometer (MODIS) provides widespread Aerosol Optical Depth (AOD) datasets for climatological and environmental health research. Since MODIS AOD clearly lacks coverage in orbit-scanning gaps and cloud obscuration, some applications will benefit from data recovery using multi-temporal AOD. Aimed at qualitatively describing the relationship between multi-te...
