Data Source

We read the atmosphere from space

ESA's Sentinel-5P satellite carries TROPOMI — the most advanced atmospheric sensor in orbit. Every day, it maps 6 pollutants across the entire planet at 3.5km resolution.

Tovqi extracts daily observations for every Indian city, fuses them with ground stations, weather data, and fire detections — creating the most complete atmospheric dataset available.

Daily Intelligence Briefing

Delhi NCR — 2024-11-18
MODERATE

NO₂ levels over Delhi NCR are projected to decrease 12% over the next 72 hours, driven by improving ventilation as wind speeds increase from 2.1 to 4.8 m/s. The boundary layer height is forecast to rise from 480m to 1,200m by Day 3...
