The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is a Japanese remote sensing instrument onboard the Terra satellite launched by NASA in 1999. It has been collecting data since February 2000. ASTER provides high-resolution images of Earth in 14 different bands of the electromagnetic spectrum, ranging from visible to ...
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 windows are useful for astronomy, remote sensing, telecommunications and other science and technology applications. In the study of the greenhouse effect, the term atmospheric window may be limited to mean the infrared window, which is the primary escape route for a fraction of the thermal radiation emitted near the surface.
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 ...
Artist's conception of OCO-2, the second successful high precision (better than 0.3%) CO 2 observing satellite. Space-based measurements of carbon dioxide (CO 2) are used to help answer questions about Earth's carbon cycle. There are a variety of active and planned instruments for measuring carbon dioxide in Earth's atmosphere from space.
The Advanced Technology Microwave Sounder (ATMS) is a 22-channel scanning microwave radiometer for observation of the Earth's atmosphere and surface. It is the successor to the Advanced Microwave Sounding Unit (AMSU) on NOAA weather satellites. ATMS units have been flown on the Suomi NPP and on the Joint Polar Satellite System.
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 ...
GPS meteorology refers to the use of the effect of the atmosphere on the propagation of the Global Positioning System's ( GPS) radio signals to derive information on the state of the (lower, neutral) atmosphere. There are currently two main operational techniques in use in GPS meteorology: GPS limb sounding from orbit, and GPS water vapour ...
