AB: Two intensive observing periods were performed during March 23, 2003 and March 18, 2004 at El Pico de Teide, Tenerife in Canary Islands. Measurements of aerosol optical thickness (AOT) and number density (ND) were obtained. The Microtops II ozone-monitor sunphotometer was used to measure aerosol optical thickness. A laser particle counter was used to measure number density. The data presented in this paper provides a picture of the relative changes in the vertical aerosol distribution along the ascent to the summit El Teide. We discuss the relationship between optical depth, vertical distribution of aerosols, air mass source region, and vertically-resolved size distribution for the two cases in spring during March 2003 and 2004.
