Geometry effect on the estimation of band reflectance in an urban area [PDF]

, 2018
Reflectance of the urban surface is an important factor for urban climate studies and can be assessed using standard remote sensing applications. However, no application considers the three-dimensional structure of the city surface and its resulting ...

Comparative assessment of atmospheric correction of Landsat imagery using Modtran and dark object subtraction. [PDF]

, 2013
Remote sensing by spectral imaging of the Earth's surface can be widely used, but only when the atmospheric influence is nullified and the data are reduced to surface reflectance units.

Simulations of detector arrays and the impact of atmospheric parameters

, 2014
In Monte-Carlo simulations of gamma-ray or cosmic-ray detector arrays on the ground (here mainly arrays of imaging atmospheric Cherenkov telescopes), the atmosphere enters in several ways: in the development of the particle showers, in the emission of ...

Terra and Aqua MODIS TEB Inter-Comparison Using Himawari-8/AHI as Reference [PDF]

Intercomparison between the two MODIS instruments is very useful for both the instrument calibration and its uncertainty assessment. Terra and Aqua MODIS have almost identical relative spectral response, spatial resolution, and dynamic range for each ...

Rethinking the atmospheric downward longwave radiation: A black-gray body model for accurate estimation

Advances in Applied Energy
Accurately estimating atmospheric downward longwave radiation is critical for applications ranging from radiative cooling to building energy efficiency. The main challenge lies in its spectral variability, which depends strongly on sky conditions such as
