Abstract
Since October 2009 an aerosol measurement data set was started at Covilhã, a small town located in the region of Beira Interior (Portugal) in the interior of the Iberian Peninsula. Until July 2010, the ambient light-absorption coefficient, 𝜎𝑎 (470 nm), 𝜎𝑎 (522 nm) and 𝜎𝑎 (660 nm), presented a daily mean value of 14.2Mm-1 (StD=8.6Mm-1), 12.1Mm-1 (StD=7.3Mm-1) and 9.6Mm-1 (StD=5.7Mm-1), respectively. Monthly variations and daily cycle are presented in this work.
