Atmospheric correction based on inherent optical properties of sea water at NIR wavelengths combined with an automated aerosol spectra determination (ASD) technique

Autor: Prakash Chauhan, Ranganath R. Navalgund, Nivedita Sanwlani

Publikováno v: International Journal of Remote Sensing. 35:3631-3650

Atmospheric correction is the process whereby atmospheric effects on sensor-recorded radiance are removed and the surface radiance is estimated. Atmospheric effects due to gaseous absorption, molecular scattering – and their seasonal as well as lat

Optimization of spectral bands for ocean colour remote sensing of aquatic environments

Autor: Aneesh A. Lotliker, T. Srinivasa Kumar, K. H. Rao, Vinay Kumar Dadhwal, Ranganath R. Navalgund, T. Preethi Latha, P. V. Nagamani

Publikováno v: SPIE Proceedings.

Selection of central wavelengths, bandwidths and the number of spectral bands of any sensor to be flown on a remote sensing satellite is important to ensure discriminability of targets and adequate signal-to-noise ratio for the retrieval of parameter

Improvement in the retrieval of humidity profiles using hybrid regression technique from infrared sounder data: a simulation study

Autor: Pradip K. Pal, M. V. Shukla, Jagat Singh Heet Bisht, Ranganath R. Navalgund, P. K. Thapliyal

Publikováno v: Meteorological Applications. 21:301-308

The profiles retrieved from sounder observations using statistical methods are extensively used as a first guess for physical retrieval. The sounder radiances are nonlinearly related to humidity profiles, making it desirable to use a suitable form of

Dust storm detection and monitoring using multi-temporal INSAT-3A-CCD data

Autor: Prakash Chauhan, Ranganath R. Navalgund, Nivedita Sanwlani

Publikováno v: International Journal of Remote Sensing. 32:5527-5539

Sand and dust on being agitated by winds often trigger huge dust storms which are characterized by high aerosol optical depth (AOD), τa, lower Angstrom exponent (α) and near-zero visibility condition. Geostationary platforms are most suitable for s

Climate Change Studies Using Space Based Observation

Autor: Ranganath R. Navalgund, Raghavendra P. Singh

Publikováno v: Journal of the Indian Society of Remote Sensing. 39:281-295

Climate change is associated with earth radiation budget that depends upon incoming solar radiation, surface albedo and radiative forcing by greenhouse gases. Human activities are contributing to climate change by causing changes in Earth’s atmosph

Characterization and transport of aerosols over the Bay of Bengal during the winter monsoon: a comparative study using in-situ and satellite measurements

Autor: Nivedita Sanwlani, Ranganath R. Navalgund, Prakash Chauhan

Publikováno v: International Journal of Remote Sensing. 32:1253-1267

Natural processes, such as dust storms and sea salt spray, and anthropogenic activities, such as the burning of fossil fuels and biomass, introduce aerosols into the atmosphere. Their concentration, geographic distribution and particle size promote s

Atmospheric Correction Over Coastal Turbid Waters of Bay of Bengal Using OCEANSAT-I Ocean Colour Monitor (OCM) Data

Autor: Prakash Chauhan, Nivedita Sanwlani, Ranganath R. Navalgund

Publikováno v: Journal of the Indian Society of Remote Sensing. 38:617-626

Space-borne ocean-colour remote sensor-detected radiance is heavily contaminated by solar radiation backscattered by the atmospheric air molecules and aerosols. Hence, the first step in ocean-colour data processing is the removal of this atmospheric
