Aerosol optical depth over a remote semi-arid region of South Africa from spectral measurements of the daytime solar extinction and the nighttime stellar extinction
Paola Formenti,Hartmut Winkler,P. Fourie,Stuart Piketh,B. Makgopa,G. Helas,Meinrat O. Andreae +6 more
TL;DR: Spectral daytime aerosol optical depths have been measured at Sutherland, South Africa (32°22′S, 20°48′E), from January 1998 to November 1999, and the comparison of daytime and nighttime measurements for the years 1998-1999 makes it possible to validate the astronomical dataset of aerosol infrared depth ( τ a ) dating back to 1991 as mentioned in this paper.

Correlation between TOMS aerosol index and astronomical extinction
TL;DR: In this article, the authors combined satellite aerosol index measurements of TOMS/Nimbus-7 and Earth Probe observations with CAMC visual extinction over La Palma from 1984 to 1997, to investigate the possibility to calibrate TOMS data in terms of astronomical extinction.

Analyses of atmospheric extinction data obtained by astronomers—III. Compilation of optical depths for 31 observatory sites
TL;DR: A compilation of mean visual atmospheric extinction (550 nm) above 31 observatory sites during the period 1950-1972 is presented and their apparent dependence on altitude is discussed in this article, where the extinction values found above maritime sites are generally quite low and are compatible with reported light scattering measurements at background locations.

Analyses of atmospheric extinction data obtained by astronomers. II - Seasonal variations in astronomical extinction
TL;DR: In this paper, archive astronomical atmospheric extinction records obtained from fifteen observatory sites were analyzed by not strictly rigorous statistical averaging procedures in order to obtain sufficiently reliable pictures of the trends and variations in atmospheric transparency for the period 1956-1972.
