The experimental Indian Nano-Satellite (INS)-2TD acquires data in a long-wave infrared (7 to 16 μm) region with fairly good spatial resolution of 175 m. Our study focuses on the retrieval land surface temperature (LST) using physics-based generalized single-channel (GSC) algorithm for INS-2TD observations. A total 597,240 at-sensor radiance simulations were carried out moderate atmospheric transmittance 5.3 radiative transfer model varying conditions pertaining surface, atmosphere, and...
MODIS Land Surface Temperature (LST) product is extensively used in agricultural studies like crop health assessment, soil moisture estimation, irrigation management, land use cover change, air-temperature retrieval and water stress detection. Numerous have Split Window (SW) algorithms to retrieve LST from TIR bands. Among them, some utilize Sensor View Angle Dependent (SVAD) or Columnar Water Vapor (CWVD) SW algorithms. Present study aims make of SVAD CWVD compare them evaluate the accuracy...
Intense, durational, and frequent heat wave becomes a concern in the modern era as they directly effect on human mortality climate. In this paper, detection is accomplished through satellite observation air temperature over Gujarat region for period of 15 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sup> - 17 March 2022. The Land Surface Temperature (LST) was derived from Indian National Satellite System (INSAT-3D) images normal year,...
Aerosol Optical Thickness (AOT) is a dynamic atmospheric parameter that holds significant importance in air quality monitoring. Gaining insights into the regional aerosol trends across various seasons unveils crucial information about their characteristics, trends, and concentrations. The sun photometer, portable instrument known for its high precision, plays pivotal role providing accurate AOT measurements. Our current study has extensively utilized photometer's data on winter summer season...
The short-wave infra-red (SWIR) region is sensitive to Carbon dioxide (CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> ) gas and this used for detection of CO source sink. Generally, three channels absorption have been purpose: 1570, 1602 2009 nm. Out all the bands, nm band has widely by various researchers, followed band. water vapor (WV) coexist in same spectral locations, which makes retrieval atmospheric concentration quite...
In this paper, the atmospheric column water vapor (WV) has been retrieved using precorrected differential absorption (APDA) technique from hyperspectral data of Next-Generation Airborne Visible/Infrared Imaging Spectrometer (AVIRIS-NG). The APDA is extended method Continuum interpolation band ratio (CIBR), and it based on Linear regression (LIRR) method. additional term reduces path radiance, which provides good accuracy over lower surface albedo. Moreover owing to use more than three bands,...
The significant amount of Carbon Dioxide (CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> ) emission causes radiative forcing in the atmosphere that increases earth's temperature. To reduce from anthropogenic activity, it is important to monitor major sources and sinks atmospheric CO such as coal-fired Thermal Power Plant (TPP). Airborne hyperspectral sensors with contiguous spectral bands have capabilities measure point source...
The study focuses on development of a method for retrieving Land Surface Temperature (LST) using MODIS (MODerate Resolution Imaging Spectroradiometer) thermal infrared (TIR) band-31 (10.78-11.28µm) and band-32 (11.7712.27µm) data through view-angle dependent split-window algorithm atmospheric correction the retrieval. For simulating at-sensor radiance, we have used Radiative Transfer Model (RTM) MODTRAN 5.3 resolution TRANsmittance). A large numbers theoretical simulations were...
