Independent emissions truth, built on open science.
Public satellite data from NASA, ESA, and JAXA. Peer-reviewed atmospheric transport models. A three-tier QA process. Audit-grade outputs aligned with ISO 14064-1 and the GHG Protocol.
Five stages from satellite radiance to a defendable number.
Every Floodlight emission figure traces back through the same pipeline, from a single industrial facility up to citywide neighbourhood maps.
Scope & Boundary
Define pollutants, geography, time window, and emission scopes for the assessment.
Data Acquisition
Pull live satellite retrievals, ancillary inventories, and meteorology. Every byte checksummed and provenance-logged.
Atmospheric Modelling
Trace each satellite reading backward through 3D wind fields using HYSPLIT and STILT Lagrangian dispersion to locate the source.
Inversion & Quantification
A Bayesian framework converts column concentrations into emission rates. Monte Carlo ensembles attach a 95% confidence interval to every number.
QA & Delivery
Three-tier quality assurance, two-person sign-off, structured outputs aligned with ISO 14064-1 and the GHG Protocol.
SAGE for Cities
The same machinery scales upward. Partition any city into a uniform grid, run SAGE inside every cell, and surface the neighbourhoods that drive the citywide budget.
