Satellite context and reviewed comparison signals
Explore a free, live Sentinel-5P atmospheric layer alongside source-backed operating sites and the strict comparison zones EcoSpace has reviewed for matching measure, unit, boundary, period, and uncertainty.
The coloured satellite layer is atmospheric NO₂ context—not a company-emissions score.
Sentinel-5P observes a regional tropospheric NO₂ column. It cannot establish a facility’s emissions, CO₂ footprint, disclosure accuracy, or company risk. Red and orange circles are reserved for a separate, human-reviewed same-unit comparison; none are created from weather data, imagery catalogue records, or company-wide disclosures.
Reviewed comparison zones
0
Published only where a reviewer documented a material, same-unit comparison.
Mapped operating sites
13
Source-backed reference points, shown in teal and not scaled by emissions.

Use the layers independently: satellite colour shows regional NO₂ context; circle zones show reviewed comparison signals; site dots show source-backed locations.
No reviewed comparison zones yet
The live satellite layer remains useful regional context. A coloured discrepancy zone appears only after a reviewer saves a compatible, source-linked assessment.
1. Comparable inputs. The reported and satellite-derived values must be the same measure and unit, linked to a reviewed operating site, and cover overlapping periods.
2. Material difference. The server calculates the difference and exposes a zone only when it clears both the documented uncertainty and a reviewer-selected significance threshold.
3. Human publication. An administrator must record the method, source URLs, quality flags, and review note before a red or orange zone can appear.
4. Screening, not a verdict. A zone prioritises research. It is not an assertion of misconduct, a legal finding, or a rating of environmental performance.
Why NO₂ is separate
NO₂ can help identify regional combustion-related air-pollution context. It is not CO₂e, a surface concentration, or a company-level measurement. EcoSpace keeps it visibly distinct from the review-only discrepancy circles.
