A pilot scale constructed wetland was setup for the studies of removal efficiency of nitrogen from treated municipal wastewater using various filter media and a macrophyte. For the current research work pulverized fly ash bricks, shale and gravel media were used and a macrophyte Phragmites was chosen to find out the removal efficiency with various filter(More)
Climate change is associated with earth radiation budget that depends upon in-comming solar radiation, surface albedo and radiative forcing by green house gases. Human activities are contributing to climate change by causing changes in Earth's atmosphere (greenhouse gases, aerosols) and biosphere (deforestation, urbanization, irrigation). Long term and(More)
The Indian Remote Sensing (IRS) satellite series has been providing data since 1988 through various Earth observation missions. Before using IRS data for the quantitative analysis and parameter retrieval, it must be corrected for the atmospheric effects because spectral bands of IRS sensors are contaminated by intervening atmosphere. Standard atmospheric(More)
This paper highlights the spatial and temporal variability of atmospheric columnar methane (CH4) concentration in the Kharif season over India and its correlation with the terrestrial vegetation dynamics. ENVISAT-SCIAMACHY product (0.5o x 0.5o) was used to analyse the atmospheric methane concentration. Weekly data covering the Kharif season (May to October)(More)
