ACTAIR's cutting-edge hybrid physical-deep learning models forecast key pollutants across Makkah and all of Saudi Arabia — empowering smarter environmental decisions.
We combine the physical accuracy of atmospheric chemical transport models with the pattern recognition power of deep learning — producing forecasts no single approach can match.
WRF-Chem atmospheric model handles emission inventories, chemical reactions, aerosol dynamics, and advection — ensuring physical plausibility of every prediction.
LSTM and Transformer networks learn residual biases and non-linear patterns that pure physics cannot capture — especially critical in complex urban environments.
The neural network loss function incorporates mass-conservation constraints from atmospheric physics, preventing physically impossible predictions.
Real-time outputs from ACTAIR's city-scale model for the Makkah region — including the Grand Mosque district and surrounding urban areas.
The regional model covers all 13 administrative regions of Saudi Arabia at 5km resolution, tracking pollutant transport, dust storms, and long-range pollution events.
Particles ≤2.5 µm — penetrate deep into lungs. Primary concern during Hajj season due to vehicle congestion and dust. Model achieves 92% accuracy at 24h lead.
Combustion byproduct from vehicles and industrial sources. Strong signal in Makkah city center during peak traffic. Forecasted from Sentinel-5P tropospheric columns.
Photochemical pollutant driven by solar radiation and precursor gases. High in summer afternoons across the Arabian Peninsula. ACTAIR models capture diurnal variation precisely.
Primarily from petrochemical industry and power plants. ACTAIR integrates Saudi Aramco emission inventories and Yanbu industrial data into the regional model.
Sentinel-5P TROPOMI, MODIS AOD, Landsat thermal — providing continuous spatial coverage across KSA at daily frequency.
NCEC network stations, MOMRA air quality sensors, and urban weather stations providing hourly validation data.
Saudi Aramco, Ministry of Energy, traffic flow data from GASTAT — enabling accurate bottom-up emission modeling.
ECMWF ERA5 reanalysis + WRF mesoscale forecasts providing wind, temperature, humidity and boundary layer drivers.
Whether you need city-scale emergency alerts or regional strategic planning — ACTAIR deploys a tailored air quality system for your municipality, region, or ministry.
