Global distribution of UV-absorbing aerosols from Nimbus 7/TOMS data
TL;DR: In this paper, a global distribution of UV-absorbing aerosols is obtained using measured differences between the 340 and the 380 nm radiances from the Nimbus 7 Total Ozone Mapping Spectrometer (TOMS) for the years 1979-1993.

Derivation of aerosol properties from satellite measurements of backscattered ultraviolet radiation: Theoretical basis
TL;DR: In this paper, the spectral variations of the backscattered radiances are used to separate aerosol absorption from scattering effects, which can be used to identify several aerosol types, ranging from nonabsorbing sulfates to highly UV-absorbing mineral dust.

The MODIS 2.1-/spl mu/m channel-correlation with visible reflectance for use in remote sensing of aerosol
TL;DR: A new technique for remote sensing of aerosol over the land and for atmospheric correction of Earth imagery is developed, based on detection of dark surface targets in the blue and red channels, but uses the 2.1-/spl mu/m channel, instead of the 3.75-/Spl mu/M channel, for their detection.

A Long-Term Record of Aerosol Optical Depth from TOMS Observations and Comparison to AERONET Measurements
TL;DR: In this paper, the authors used the Total Ozone Mapping Spectrometer (TOMS) on board the Nimbus-7 (1979-92) and the Earth Probe (mid-1996 to present) satellites to derive a long-term record of aerosol optical depth over oceans and continents.

TL;DR: In this article, the authors summarized the science behind this change in remote sensing, and the sensitivity studies and applications of the new algorithms to data from present satellite and aircraft instruments, and concluded that the anticipated remote sensing of aerosol simultaneously from several space platforms with different observation strategies, together with continuous validations around the world, is expected to be of significant importance to test remote sensing approaches to characterize the complex and highly variable aerosol field.
