Abstract
The urban AQF Tool displays forecasted air pollutant concentrations for the region of Hamburg in Northern Germany based on a complex model developed at Helmholtz-Zentrum Hereon in Geesthacht, Germany. The tool considers various gaseous pollutants and different pollution sources for largely populated urban areas with intense harbour activities. A 100m resolution estimation and different charts are calculated to allow for easy access of current day conditions. To make the data easily understandable, the pollutant concentrations are summarized in the hourly indicator, the air quality index (AQI). The index uses a rank ranging from 1 (good) to 6 (poor) for total air quality. The dataset is updated every day and displayed in an ESRI GIS environment. The dataset can be accessed in a web browser with the URL: https://hcdc.hereon.de/urbanaqf.
