On August 22, 2002, a vicarious calibration (VC) experiment of MERIS, a pushbroom imaging spectrometer on ESA’s ENVISAT, was performed. The purpose of this experiment was the acquisition of in-situ measurements of surface and atmospheric conditions over a bright, uniform target. These data were then used to compute top-ofatmosphere (TOA) radiances, which were correlated with the MERIS TOA radia...

Background: Sediments are inseparable fractions of wetland ecosystems that work as a his-torical archive in the process of recording heavy metal aggregation changes. This study was carried out for assessing Co, Ni, and Zn in sediment samples of Mighan Wetland using geo-accumulation index in 2013. Methods:The sediment samples were taken from 11 stations. The samples were subjected to bulk dige...

this research was performed to evaluate the potentials of landsat mss data for map-ping land features in arid zones of southeastern esfahan, iran. databases of the area were formed using all available relevant maps and reports which were supported by fieldwork. a supervised image classification approach was used and thirty-two training areas were applied. separability of the spectral classes wa...

introduction: playa is one of the most important landscapes in arid regions which covers about 1% of the world's total land area. study of playas is important from different points of view especially pedology, sedimentology, mineralogy, environmental geology, groundwater and surface water chemistry. more than 60 playas have been identified in iran. considering the fact that playas and surroundi...
