RT Journal Article T1 Aerosol size distribution from inversion of solar radiances and measured at ground-level during SPALI10 campaign A1 Fernández Gálvez, Jesús A1 Guerrero Rascado, Juan Luis A1 Molero, Francisco A1 Lyamani, Hassan A1 Revuelta, María Aránzazu A1 Navas Guzmán, Francisco A1 Sastre Marugán, Mariano A1 Bravo Aranda, Juan Antonio A1 Fernández, Alfonso Javier A1 Granados Muñoz, María José A1 Gómez Moreno, Francisco Javier A1 Olmo, Francisco A1 Pujadas, Manuel A1 Alados Arboledas, Lucas AB A comparison of columnar versus ground-level measurements of aerosol size distribution is presented. The purpose was to understand what atmospheric conditions are most suitable for closure between: 1) ground-based remote sensing instruments measuring vertical columnintegrated optical and microphysical properties and 2) ground-based in-situ aerosol instruments measuring microphysical properties at the surface scaled to height using aerosol backscatter profiles from lidar measurements. Measurements were taken during the SPAM 0 (SPAin Lidar Intercomparison 2010) field campaign at Madrid from 18 October to 5 November 2010 within the frame of the EARLINET-ASOS project. Monitoring included aerosol measurements of size distribution as well as chemical composition. Both combined Scanning Mobility Particle Sizer and Optical Particle Counters were used for determining aerosol size distribution ranging from 15 nm to 10 mu m. Additionally, the column-integrated characterization of the atmospheric aerosol was provided by a sun tracking photometer using a methodology based on non-spherical particles. Two different synoptic situations were analyzed: a stagnation scenario with growing pollution concentrations and a clean atmosphere with low aerosol particle load. The shape of the ground-level aerosol size distribution matches with the column-integrated in both scenarios but absolute values disagree, particularly with stagnation. Better agreement was found for clean atmospheric situations when the mixing layer reaches higher altitudes and the aerosol concentration within the atmosphere follows an exponential decay profile with height (C) 2012 Elsevier B.V.
