FORECASTING

The air quality forecasting is one of the valuable additions to the Dubai Air Environment platform. The forecasting system relies on inputs from emission data for all sectors and sources in the Emirate (industry sector, transportation sector, energy production sector), meteorological or weather data forecasts, and terrain data such as soil, vegetation, roughness/slope. The forecasting system allows air quality forecasting three days in advance. Historical and current observations of air pollutant's concentrations, recorded at Dubai's air quality monitoring stations, provide improvements towards the simulation accuracy and overall model performance.

EMISSION INVENTORY

Dubai Municipality has developed an integrated online system to manage air emissions generated from various sectors in the emirate, such as the industry, energy and transport sectors. The emission inventory is comprehensive database that supports decision-making processes and draws future environmental plans and strategies, which support the air quality targets in the Emirate. Additionally, the system allows preparation of detailed modelling air emission maps highlighting the main sources of air pollution and their contribution to the overall air quality. The emission's data for stationary and non-stationary sources are evaluated in accordance with the EMEP/EEA Air Pollutant Emission Inventory Guidebook 2016. The most common approach is to include the activity data information and coefficients that quantify the emissions per unit activity, called emission factors. The emission factors differ depending on the pollutant, sector and technology used. The system outputs support identification of impacted areas and consequently identification of priority emission reduction plans and locations of future air quality monitoring stations.
