The LANDSAT- TM Band-6 raw data is converted to black body temperature in degree Celsius by using IDRISI software model. Recent two decade data is used for detection of surface temperature change during 1990- 2010 to estimate increase rate of increase in temperature to understand the intensity of Global warming in the present and previous decades. It is evident that surface temperature of Tapi Basin in the Central part of India increased from 41.6 oC in May 1990 to 44.1 oC in May 2010.This fact proves the intensity of Global warming. The spatio-temporal change is also detected to classify the basin in micro-thermal zones. Recently, Tapi basin facing several problems attributed to this temperature change in river channel as well as in basin area. The prominent channel change is aggradations. Aggradations lead to the decreases of channel capacity causing high floods even in low to moderate rainfall. The basin is facing problem of depletion of water level in channel as well as water table and salinization of basin soil due to accelerated rate of evaporation with increase of the temperature. The Tapi basin is situated in core part of India. It extents between 20° 4' 33.2574" N to 22° 1' 3.2556" N lat and 72° 38' 11.8752" E to 78° 16' 41.865" E log and covers 65145 sq.km area with 724 km. east-west length of basin .The basin is underlined Deccan trap formations and comes under the tropical monsoon regime

Nitrogen oxides as well as ozone play a central role in atmospheric chemistry and the improvement of techniques and instruments allowing for a better understanding of the distributions and behaviour of the mentioned compounds are strongly required by the scientific community. Thanks to the new satellite technology, global scenes of the dynamical and chemical processes of the atmospheric compounds can be drawn. Ground-based equipments have to be used for comparison/validation of the satellite retrievals. The LIS (Lampedusa Island Spectrometer) instrument is a SPATRAM (SPectrometer for Atmospheric TRacers and Aerosol Measurement) type equipment allowing for the measurements of spectral sky radiance along the zenith direction, in its standard configuration. Here, the first results obtained with the LIS spectrometer installed in the centre of Palermo (Italy) for nitrogen dioxide (NO2) and ozone (O3) total columns, and the comparisons with data from the OMI – Ozone Monitoring Instrument on board of AURA satellite for O3 total column are presented and discussed.

The main environmental issues affecting the broad acceptability of NPP (Nuclear Power Plant) are the emission of radioactive materials, the generation of radioactive and heat waste, and the potential for nuclear accidents. Satellite remote sensing is an important tool for spatio-temporal analysis and surveillance of environment, thermal heat waste of waters being a major concern in many coastal ecosystems involving nuclear power plants, as sharp changes in water temperature can significantly affect the distribution and physiology of aquatic biota and contribute to global warming. The thermal plume signature in the NPP hydrological system in TIR (Thermal Infrared) spectral bands of Landsat TM and ETM TIR band 6 as well as ASTER TIR bands time series satellite have been used for WST (Water Surface Temperature) detection, mapping and monitoring. As a test case the methodology was applied for NPP Cernavoda, Romania during period of 1990-2010 years. Thermal discharge from two nuclear reactors cooling is dissipated as waste heat in Danube-Black -Sea Channel and Danube River. If during the winter thermal plume is localized to an area of a few km of NPP, the temperature difference between the plume and non-plume areas being about 1.5 ^oC, during summer and fall, is a larger thermal plume up to 5-6 km far along Danube Black Sea Channel, the temperature change being of about 1.0 ^oC.
