Atmospheric correction. 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 ...
Atmospheric lidar. For broader coverage of this topic, see Lidar. Atmospheric lidar is a class of instruments that uses laser light to study atmospheric properties from the ground up to the top of the atmosphere. Such instruments have been used to study, among other, atmospheric gases, aerosols, clouds, and temperature.
Atmospheric Sciences Laboratory. The Atmospheric Sciences Laboratory (ASL) was a research institution under the U.S. Army Materiel Command that specialized in artillery meteorology, electro-optical climatology, atmospheric optics data, and atmospheric characterization from 1965 to 1992. [1] ASL was one of the seven Army laboratories that merged ...
Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object, in contrast to in situ or on-site observation. The term is applied especially to acquiring information about Earth and other planets .
Meteorological instrumentation. Galileo thermometer. Meteorological instruments (or weather instruments), including meteorological sensors (weather sensors), are the equipment used to find the state of the atmosphere at a given time. Each science has its own unique sets of laboratory equipment. Meteorology, however, is a science which does not ...
Remote sensing of mesoscale cellular convection. Mesoscale cellular convection (MCC) is a form of buoyantly driven convection that can provide the planetary boundary layer with cumulus clouds at the top of the boundary layer. MCC generally occurs over ocean regions and is primarily found off the coasts of major continents particularly in North ...
The optical window is the portion of the optical spectrum that is not blocked by the Earth 's atmosphere. The window runs from around 300 nanometers (ultraviolet-B) up into the range the human eye can detect, roughly 400–700 nm and continues up to approximately 2 μm. [ 1 ][ 2 ] Sunlight mostly reaches the ground through the optical ...
Atmospheric sounding or atmospheric profiling is a measurement of vertical distribution of physical properties of the atmospheric column such as pressure, temperature, wind speed and wind direction (thus deriving wind shear), liquid water content, ozone concentration, pollution, and other properties. Such measurements are performed in a variety ...
