The Gli 380-nm Channel – Application for Satellite Remote Sensing of Tropospheric Aerosol
نویسندگان
چکیده
The Global Imager (GLI) onboard ADEOS-2 is the first medium-resolution Earth observation satellite sensor that is able to combine measurements from the near-UV to the IR wavelength region. This work investigates a newly available channel in the near-UV to retrieve the optical thickness and single-scattering albedo of aerosols. Due to the low reflectivity of most surfaces in the near-UV, this wavelength range is particularly useful to detect aerosols both over the oceans and lands. The 1-km resolution and wide spectral range of GLI data makes it possible to retrieve atmospheric aerosols parameters with higher accuracy due to accurate cloud screening. This paper describes the retrieval method, gives a sensitivity analysis, and presents examples of retrievals of aerosols.

Satellite remote sensing reveals regional tropospheric aerosol trends.
The Global Aerosol Climatology Project data product based on analyses of channel 1 and 2 AVHRR radiances shows significant regional changes in the retrieved optical thickness of tropospheric aerosols which had occurred between the volcano-free periods 1988-91 and 2002-05. These trends appear to be generally plausible, are consistent with extensive sets of long-term ground-based observations thr...

Human groups have considered the Behshahr plain of Mazandaran in the past Due to its particular geographical shape, location between the Caspian Sea and mountains, and the existence of some rivers in the region. However, our knowledge of this area is limited to several published surveys and archaeological investigation of its ancient sites. No detailed research has conducted on the formation of...
متن کاملSatellite remote sensing of surface air quality
Satellite remote sensing of air quality has evolved dramatically over the last decade. Global observations are now available for a wide range of species including aerosols, tropospheric O3, tropospheric NO2, CO, HCHO, and SO2. Capabilities for satellite remote sensing of these species in the boundary layer are reviewed for current instruments, along with physical processes affecting their accur...
متن کاملThe MODIS 2.1-μm channel-correlation with visible reflectance for use in remote sensing of aerosol
A new technique for remote sensing of aerosol over the land and for atmospheric correction of Earth imagery is developed. It is based on detection of dark surface targets in the blue and red channels, as in previous methods, but uses the 2.1m channel, instead of the 3.75 m for their detection. A 2.1m channel is present on ADEOS OCTS and GLI, and planned on EOS-MODIS and EOSP, and a similar 2.2m...
