| contents | The Atmospheric Extinction of San Pedro Mártir W. J. Schuster & L. Parrao L. Parrao W. J. Schuster Física, Astronomía y Matemáticas ATMOSPHERIC EXTINCTION TECHNIQUES: PHOTOMETRIC ATMOSPHERES: TERRESTRIAL The atmospheric extinction of San Pedro Mártir (SPM) is analyzed using 13 color determinations from 294 nights of observations over the years 1973{1983, plusthe extinction measures from 272 nights of uvby observations over the years 1984{1999. The general behavior of the normal extinction at SPM is given and analyzedas a function of wavelength and as a function of time. The average atmosphericextinction at SPM, excluding volcanic outbursts, has not changed significantly overthe period 1973{1999. A simple 3-component model for the extinction above SPMis derived and presented; the normal, average, non-volcanic aerosols above SPMare well fit by kp = 0:0254_0:87. The extinction determinations for the periodsfollowing the volcanoes El Chichón and Pinatubo are given: 13C data show theeffects of El Chichón and uvby for Pinatubo. The extinction curves and theirvariations are analyzed to study the volcanic aerosols and their evolution withtime. The Apr/May 98 observing run, when large non-volcanic extinction variationsoccurred, is also studied and deductions drawn concerning these unusual aerosols. 2001 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57137208 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.2 Vol.37 |
