abstract = {As part of the columnar aerosol characterization and establishment of a climatology representative of the nort-center region of Spain, a study on the discrimination and classification of aerosol types has been carried out. This work focuses on the estimation of the desert type aerosol which is transported to this region, using a detailed inventory of the events, associated days and frequency, atmospheric scenarios and other characteristics of this type of intrusion over a period of 10 years, between 2003 and 2012. The method employed here is similar to that documented in Toledano, et. al., (2007a, b), which is based on a few threshold criteria on the values of aerosol parameters AOD-alfa, adapted to the particularity of this region of study, characterized as clean continental. The detection of an episode or intrusion of desert type is not that complicated, however it can be difficult to determine the exact number of days, as most cases correspond to mixed aerosols, which leads to high values of the alpha, above 1, low values being observed only in the case of strong events. For this reason it was chosen to distinguish between the days with alpha values below 1 for pure desert dust, in comparison with those of mixed aerosol D-C (Desert-Continental), with alpha between 1 and 1.5. With the aim to improve the classification of the days, additional information on PM10 data from the background station of Peñausende (Zamora), Campisábalos (Guadalajara) and Barcarrota (Badajoz) belonging to the EMEP network, have been used. The two latter help to determine the possible occurrence of a dust episode reaching the region. Moreover, airmass backtrajectories from the HYSPLIT model and satellite images from the MODIS sensor, synoptic maps as well as forecast maps from the NAAPS model were examined, with the aim to perform a better discrimination, characterization and estimation. The combination of all this information has facilitated the manual inventory which will constitute a basis for the validation of an automatic method for future precise detection and estimation of this type of aerosol in the studied region.},

abstract = {The work carried out within the AEROPA project, funded by the Spanish Ministry for Research and Innovation, is presented. The project is entitled “Characterization of AERONET aerosol observations over Europe for use into objectives of EMEP network (AEROPA)” and it was designed to assess and analyze of the aerosol optical depth (AOD) and Ångström exponent (AE) delivered by AERONET, for the comparison over the European region with the EMEP/MSC-W model. For this project various objectives were defined: a) the diagnosis of AERONET data quality over Europe and North Africa for aerosol characterization, b) the characterization of the AOD-AE data over Europe and its significance for climatology. c) comparison of AOD-AE AERONET data with EMEPMSC-W model belonging to the Norwegian Meteorological Institute (MET.NO), in the European area taking into account the different AERONET data quality levels; and e) the discrimination and classification of aerosol types in Europe based on their optical properties and air mass origin. The aim of this proposal is establishing a set of recommendations about the correct use of the column-integrated aerosol data provided by AERONET (Aerosol Robotic Network,), within the objectives and scope of the European network EMEP (European Monitoring and Evaluation Program o Co-operative Program for Monitoring and Evaluation of the Long-Range Transmission of Air Pollutant in Europe). To achieve these objectives it was necessary to develop a relational database that contains the aerosol properties over the Europe area. This relational database is powered by the CÆLIS system (www.caelis.uva.es), developed by the GOA-UVA, and can be accessed through a web interface. One of the main objectives is the development, application and operation of a simplified version of the Unified EMEP model, to estimate the aerosol optical depth. The U-EMEP is a chemical transport model (CTM) developed by the MSC-W (Meteorological Synthesizing Centre-West) center, Norwegian Meteorological Institute. This model estimates the concentration of various atmospheric components, by tracking the long-range transboundary atmospheric transport, at a global, regional or local scale. The simplified version provides aerosol optical depth (AOD), by means of an aerosol model that estimates this radiative property. The AOD is not a common product in CTM, but nowadays it is seen as a necessary quantity for the global aerosol characterization. We have carried out a wide evaluation of other aerosol parameters such as: the microphysical parameters, the asymmetry parameter, the single scattering albedo, etc., a work that was not included in the initial objectives of the Project. This extensive evaluation has the advantage to give a more complete characterization of the aerosol properties that are provided by AERONET. Most of these results can be seen in this website through the selection of a given site. Plotting and mapping tools are also available upon registration. This system, which is continuously improving, was designed for aerosol data analysis related to aerosol studies and we believe that it will be useful for most AERONET users in Europe and other research groups working in this field.},

During the last years a new optical calibration facility have been developed and deployed at the Izaña Observatory for the calibration and characterization of radiation instrumentation within research activities. The new systems are the result of a joint effort of the Izaña Atmospheric Research Center (AEMET) and the Atmospheric Optics Group of Valladolid University (GOA-UVA). The high altitude Izaña Atmospheric Observatory is involved in several national and international atmospheric and environmental research networks and programs (i.e. GAW, BSRN, AERONET, NDACC, RBCC-E) in which is crucial a robust and traceable Quality Assurance & Quality Control system for the different broad band radiometers, photometers and spectrometers, which measure, among other ones, spectral solar radiation, aerosol optical depth and total ozone amount. This new facility allows the absolut, spectral and cosine response calibration of the above mentioned instrumentation in an isolated dark room where several set-ups are available for each kind of response characterization. At this time there are six set-ups running at the laboratory: one for the radiance calibration, one for the calculation of the angular response, one for the spectral response characterizarion, one for the slit function determination and two (vertical and horizontal oriented ones) for the irradiance calibration. The different set ups account for the different specific requirements of each sensor to be calibrated depending on its physical features as shape, size and weight. The systems have been built in a modular way, and the control and acquisition software have been developed such way the calibration facility could be easily adapted and meet the specific requirements of each program. The systems, as well as some examples of calibrations, are shown in this presentation.
