Urban Air Quality Trends from Sentinel-5P Aerosol and NO2 Data
Track pollution plume dynamics and long-term air quality trends over cities and industrial corridors. Klarety processes Sentinel-5P aerosol optical depth and NO2 column density to estimate surface AQI proxies and identify emission source contributions. Public health agencies use weekly trend reports to issue alerts and plan intervention.

Weekly pollution trend reports from one city prompt
Klarety agents process Sentinel-5P NO2 and aerosol data and return surface AQI proxy maps with emission source contributions.
NO2 column and aerosol depth AQI estimation
Agents apply regression models to convert tropospheric NO2 and aerosol optical depth to surface-level AQI proxy values.
Pollution rasters for environmental health GIS
Export NO2 concentration rasters and AQI proxy grids for public health exposure model and environmental GIS integration.
Sentinel-5P NO2 tropospheric column AQI proxy mapping
Klarety agents compute weekly Sentinel-5P TROPOMI NO2 tropospheric column composites, apply an empirical surface concentration conversion factor, and map AQI proxy at 3.5km resolution. Emission source hotspots are identified by spatial clustering of NO2 column anomalies above urban background. Output is a weekly NO2 map, AQI proxy raster, and emission source cluster table.
