Atmospheric correction is the process of removing the scattering and absorption effects of the atmosphere on the reflectance values of images taken by satellite or airborne sensors. [ 1 ] [ 2 ] Atmospheric effects in optical remote sensing are significant and complex, dramatically altering the spectral nature of the radiation reaching the ...
Focusing (psychotherapy) Focusing is an internally oriented psychotherapeutic process developed by psychotherapist Eugene Gendlin. It can be used in any kind of therapeutic situation, including peer-to-peer sessions. It involves holding a specific kind of open, non-judging attention to an internal knowing which is experienced but is not yet in ...
Downscaling is any procedure to infer high-resolution information from low-resolution variables. This technique is based on dynamical or statistical approaches commonly used in several disciplines, especially meteorology, climatology and remote sensing. [1][2] The term downscaling usually refers to an increase in spatial resolution, but it is ...
Atmospheric lidars can be either ground-based, airborne or satellite-based depending on the type of measurement. Atmospheric lidar remote sensing works in two ways – by measuring backscatter from the atmosphere, and; by measuring the scattered reflection off the ground (when the lidar is airborne) or other hard surface.
Aerial perspective, or atmospheric perspective, refers to the effect the atmosphere has on the appearance of an object as viewed from a distance. As the distance between an object and a viewer increases, the contrast between the object and its background decreases, and the contrast of any markings or details within the object also decreases.
Sensory threshold. In psychophysics, sensory threshold is the weakest stimulus that an organism can sense. Unless otherwise indicated, it is usually defined as the weakest stimulus that can be detected half the time, for example, as indicated by a point on a probability curve. [1] Methods have been developed to measure thresholds in any of the ...
Remote sensing in oceanography is a widely used observational technique [1] which enables researchers to acquire data of a location without physically measuring at that location. Remote sensing in oceanography mostly refers to measuring properties of the ocean surface with sensors on satellites or planes, which compose an image of captured ...
