Germany · Startup
Uses thermal-infrared cameras on nanosatellites for global wildfire detection and monitoring.
A global leader in weather, environmental, and industrial measurements.
Uses a constellation of nanosatellites to collect radio occultation data, fed into ML models for forecasting.
Atmospheric sensing stacks combine hyperspectral nanosat constellations, high-altitude drones, and curbside sensor meshes to measure greenhouse gases, aerosols, and pollutants at unprecedented resolution. Satellites from GHGSat, MethaneSAT, Carbon Mapper, and PlanetiQ detect methane leaks, NOx plumes, and wildfire smoke globally, while city networks deploy low-cost electrochemical nodes and open-path sensors on light poles to monitor street-level air quality. Edge computing and standardized APIs stream data into digital twins, enabling regulators and companies to attribute emissions to specific assets.
Utilities use this infrastructure to verify pipeline integrity, oil and gas majors commit to leak detection and repair schedules, and municipalities enforce clean-air zones in near real time. Insurers and investors subscribe to feeds to assess climate risk, and carbon-credit registries rely on independent measurements to validate offset claims. Paired with AI models, the network can forecast smoke trajectories, issue health alerts, or trigger automatic shutoffs when leak thresholds are exceeded.
The tech is TRL 7 but scaling requires calibration standards, interoperability, and privacy safeguards. Governments are adopting open-data mandates (EU Copernicus expansion, US EPA Methane Rule) and funding sensor deployments in frontline communities to ensure environmental justice. As costs drop, atmospheric sensing becomes a core layer of climate accountability, making emissions as visible—and actionable—as financial transactions.
