Abstract | Links | BibTeX | Tags: Biomass burning urban industrial, Coarse and fine modes, Columnar and surface aerosols, desert dust, High turbidity episodes @article{MATEOS2020104835, The identification and characterization of High Atmospheric Turbidity (HAT) episodes is a key objective of global aerosol monitoring. This study presents a comparison of three different methodologies that were used to identify HAT episodes in the north-central Iberian Peninsula. The first methodology (named C&S inventory) is based on columnar aerosol optical depth (AOD from the Aerosol Robotic Network, AERONET) and surface particulate matter concentrations (PMx from the European Monitoring and Evaluation Programme, EMEP) as well as ancillary information. Another methodology (named SPR) is based on PM surface concentrations levels and ancillary information. Both methods are carefully reviewed by human observers. A third method, based only on fine and coarse mode values of AOD was also analysed. This method (the SDA or Spectral Deconvolution Algorithm) is found to be a good operational candidate for automating the identification of HAT episodes. The three methods allow for the identification of mineral desert dust (coarse type ‘D’) aerosols and aerosols of fine type, ‘A’ (i.e. biomass burning or polluted aerosols): their mixture, categorized as ‘MD’ and ‘MA’ classes (depending of the prevailing ‘D’ or ‘A’ type) is only identified in the C&S and SDA inventories. The three inventories show about 60% coincidence across a 2005–2014 reference period. When the C&S and SDA inventories are compared, the agreement is very high if columnar aerosol data is available: >90% for desert aerosol type and >70% for fine aerosol type. The comparative study of these three aerosol inventories was motivated by the need to automate existing methodologies. |

Abstract | Links | BibTeX | Tags: aerosol, desert dust, tesis @phdthesis{Velasco-Merino2020, Este trabajo aborda el estudio de eventos de alta turbiedad atmosférica debida a aerosoles, que son las partículas en suspensión en la atmósfera. De forma particular, se ha investigado la identificación de episodios de polvo mineral del Sahara, las propiedades ópticas y microfísicas de este aerosol desértico y cómo se ven afectadas por el transporte sobre el Atlántico desde la costa oeste de África hasta la cuenca del Caribe. El estudio de los métodos actualmente empleados para la detección de eventos de alta turbiedad, indicó la necesidad de desarrollar un método automatizado de detección de dichos eventos de aerosol. Además se han introducido mejoras en el análisis de medidas radiométricas, como es incluir el canal de medida del infrarrojo medio (1640nm) para el análisis espectral del espesor óptico de aerosoles y en el estudio de los productos obtenidos mediante algoritmos de inversión. |
