Resumo

The following study is in the logical continuation of recent and ongoing works carried out at GOAUVA which endeavor to compare and evaluate satellite MODIS (Moderate Resolution Imaging Radiometer)-derived aerosol climatologies against those measured by sun photometers of the AERONET-RIMA network, at El Arenosillo (37.1N, 6.7W, Huelva) and Palencia (42.0N, 4.5W), representative of the southwestern and north-central Spanish areas respectively. The following study proposes a detailed analysis of a dust intrusion which was observed over the two regions aforementioned, in March 2004. The analysis is based on the time series of several parameters: the Aerosol Optical Depth (AOD), the Ångström exponent (Alpha), and the fine-mode AOD fraction (FF).
