Relationship between Pollen Concentration and Meteorological Condition in an Urban Area

Relationship between Pollen Diseases and Meteorological Factors in Japan

Pollen counts have been increasing and patients suffering from pollen allergy now exceed 14% of the population of Japan. The amount of pollen has a positive relationship with the air temperatures and solar radiation of the preceding summer. Using this relationship, pollen counts of the next season are estimated roughly. According to the results of cedar flower observations in late autumn, the f...

The relationships between meteorological parameters and air pollutants in an urban environment

Meteorological parameters play a significant role in affecting ambient air quality of an urban environment. As Dhaka, the capital city of Bangladesh, is one of the air pollution hotspot among the megacities in the world, however the potential meteorological influences on criteria air pollutants for this megacity are remained less studied. The objectives of this research were to examine the rela...

Artificial neural network model of the relationship between Betula pollen and meteorological factors in Szczecin (Poland)

Birch pollen is one of the main causes of allergy during spring and early summer in northern and central Europe. The aim of this study was to create a forecast model that can accurately predict daily average concentrations of Betula sp. pollen grains in the atmosphere of Szczecin, Poland. In order to achieve this, a novel data analysis technique--artificial neural networks (ANN)--was used. Samp...
