  • Assessment of the correlations between aerosol optical depth and air temperature
    Frashëri, Neki ...
    ABSTRACT Aerosols play a pivotal role in Earth's climate system, and their influence on temperature and other meteorological parameters remains a subject of active research. Aerosol Optical Depth ... (AOD) is closely associated with meteorological factors such as temperature and humidity because these variables can impact the concentration of aerosols in the atmosphere. The relationship between AOD and temperature is intricate, contingent on the specific attributes of the aerosols present in the atmosphere and the prevailing meteorological conditions. Some studies have reported a positive correlation between AOD and temperature, while others have found negative correlations or no discernible pattern. Aerosols can scatter and absorb sunlight, leading to either cooling or heating effects on the Earth's surface. This effect can be particularly pronounced in regions with high aerosol concentrations, such as urban areas or areas with elevated pollution levels. This study utilizes data from the MERRA-2 dataset, a comprehensive compilation of atmospheric and weather data acquired through satellite and other observing platforms. The analysis focuses on the territory of Albania, situated in Southeast Europe. The average correlation coefficient across the entire region is a statistically significant 0.56, with higher values observed in interior regions. A correlation coefficient ranging from 0.6 to 0.7 between AOD of black carbon and air temperature suggests a strong positive relationship between these two variables. Conversely, the relatively low correlation coefficients observed for other aerosol components such as organic carbon, sulfates, sea salt, and mineral dust with air temperature (Tair) imply weaker associations. Notably, the correlation coefficient for sea salt exhibits both positive and negative values. Keywords: aerosols, atmospheric parameters, correlation
