干旱区生态环境知识资源中心

In this work we analyze the impact of a strong Saharan dust intrusion on the DNI registered at two sites in the southeast of Spain: University of Almeria (UAL) and Almeria Solar Platform (PSA) located in Tabernas (Almeria). Direct normal irradiance (DNI) modelling with ESRA procedure presents high Linke turbidity values, being extremely high at the first site. DNI simulations using SMARTS code in the PSA emplacement, using AERONET data from PSA and maximum desert aerosol type, show a great accordance with the measured DNI values. In the UAL emplacement, SMARTS simulation of DNI values seems also to be compatible with maximum desert aerosol type aerosols. Visibility values are in good accordance with the extinction coefficients derived from the CL51 ceilometer profiles.
