Semi - annual report on activities associated with the MODIS task : Global Monitoring of Aerosol Properties , Water Vapor , Cloud Structure
نویسنده
چکیده
The overall objective of this investigation is to develop algorithms, based on the unique properties of the MODIS sensor, for remote sensing of aerosol and cloud characteristics, and remote sensing of water vapor. The derived aerosol, cloud and water vapor properties will be used to develop aerosol climatology, to perform atmospheric corrections of the MODIS imagery in the solar region, as well as to conduct studies of the environment. These remote sensing products, derived from the MODIS imagery, will contain a unique source of information that will be used to answer basic scientific questions regarding the impact of human activity on the environment: What is the contribution of tropical biomass burning on atmospheric concentrations of trace gases and the resulting climate change and changes in atmospheric chemistry. What is the effect of particulates formed in the air, from emission of SO2 in the process of fossil fuel burning, on counteracting the greenhouse effect of the emitted CO2. What is the effect of anthropogenic pollution on natural vegetation and on the quality of life in a densely populated urban environment. How do clouds interact with aerosol and water vapor, and what is the impact of this interaction on cloud microphysics, structure and climate. The team member leads 6 core products and one post launch products, as well as 7 scientific investigations using MODIS data.

Remote sensing of cloud, aerosol, and water vapor properties from the moderate resolution imaging spectrometer (MODIS)
The Moderate Resolution Imaging Spectrometer (MODIS) is an earth-viewing sensor being developed as a facility instrument for the Earth Observing System (EOS) to be launched in the late 1990’s. MODIS consists of two separate instruments that scan a swath width sufficient to provide nearly complete global coverage every 2 days from a polar-orbiting, sun-synchronous, platform at an altitude of 705...
متن کاملCloud and aerosol properties, precipitable water, and profiles of temperature and water vapor from MODIS
The Moderate Resolution Imaging Spectroradiometer (MODIS) is an earth-viewing sensor that flies on the Earth Observing System (EOS) Terra and Aqua satellites, launched in 1999 and 2002, respectively. MODIS scans a swath width of 2330 km that is sufficiently wide to provide nearly complete global coverage every two days from a polar-orbiting, sun-synchronous, platform at an altitude of 705 km.

متن کاملSolar radiation budget and radiative forcing due to aerosols and clouds
[1] This study integrates global data sets for aerosols, cloud physical properties, and shortwave radiation fluxes with a Monte Carlo Aerosol-Cloud-Radiation (MACR) model to estimate both the surface and the top-of-atmosphere (TOA) solar radiation budget as well as atmospheric column solar absorption. The study also quantifies the radiative forcing of aerosols and that of clouds. The observatio...

describing the algorithms for simultaneous remote sensing of aerosol properties over land and ocean from spectral reflectance observed by EOS-MODIS (both Terra and Aqua). The Collection 5 (C005) algorithm retrieves the aerosol optical depth (AOD-proportional to the aerosol total loading in the vertical column) and proxies for the size distribution (such as Fine-Weighting (FW)) of the ambient (u...
