21 There is presently renewed interest in diurnal variations of stratospheric and mesospheric ozone 22 for the purpose of supporting homogenization of records of various ozone measurements that are 23 limited by the technique employed to being made at certain times of day. We have made such 24 measurements for 19 years using a passive microwave remote sensing technique at the Mauna 25

abstract evapotranspiration (et) determination is a key factor for irrigation scheduling, water balance, irrigation system design and management and crop yields simulation. therefore many scientists have tried to estimate evapotranspiration in different spatial and temporal scales. remote sensing is a one of new technique in estimation of et in regional scales. so, in this study it’s tried to e...

Over the past decades, most of the remote sensing studies dealt with natural environment. The advance of remote sensing satellites and the innovative methods of proceeding high resolution images have contributed to integrated urban studies. This project is an attempt to use remote sensing technology so as to monitor the urban sprawl of the city of Thessaloniki and detect the changes occurred th...

An important approach to unsupervised pixel classification in remote sensing satellite imagery is to use clustering in the spectral domain. The problem of classifying an image into different homogeneous regions is viewed as the task of clustering the pixels in the intensity space. In particular, satellite images contain landcover types some of which cover significantly large areas, while some (...

desertification relates to the both the process and end state of drylands degradation. salinization and alkalinization are two indicators of soil degradation in arid and semi-arid regions. the main objectives of this research is monitoring of soil salinity using high spectral and spatial resolution of remote sensing to assess desertification in the marvast plain, yazd province. two images of te...
