DATA.SAT

Year-Round Global Coverage

High-resolution Satellite Methane Monitoring & Detection

GHGSat’s satellite methane monitoring service, DATA.SAT delivers independent, high-resolution satellite methane emissions data attributed to individual facilities to support operational response, regulatory defensibility, and portfolio oversight.

Designed for frequent monitoring across distributed asset portfolios, DATA.SAT enables detection of both persistent and episodic methane emissions at the facility level, beyond what one-time surveys can provide.

What DATA.SAT Enables

Decision-Grade Methane Oversight Across Assets & Jurisdictions

Global facility-scale detection: Monitor emissions from any site in the world without sending a crew on the ground. DATA.SAT detects methane releases at 100 kg/h at 50% PoD, capturing emissions that wide-area screening missions cannot resolve

Near-daily revisit: A 15-satellite constellation observes priority sites every one to two days, catching intermittent emissions and building a high-frequency measurement record

Rapid response when it matters: Confirm suspected releases within 24 hours of acquisition, supporting incident response for ruptures, blowouts, and unplanned releases, complementing ground reports with independent measurement on the same operational timeline

Offshore platform monitoring: Glint-mode acquisition extends facility-scale methane detection to platforms, FPSOs, and marine infrastructure at sea.

Mitigation verification. Repeated measurements provide an independent, time-stamped abatement record for regulatory filings, certifications, and contractual milestones. 

Historical record on demand. The DATA.SAT Catalog preserves every observation for retrospective analysis, due diligence, and multi-year trend reconstruction. 

Within GHGSat’s tiered monitoring framework, DATA.SAT provides frequent and wide-area satellite methane monitoring. 

What DATA.SAT delivers

DATA.SAT Data Outputs

DATA.SAT delivers actionable methane data designed to support operational response, regulatory reporting, and portfolio analysis. Outputs are securely accessed through GHGSat’s emissions analytics platform, SPECTRA, or programmatically through the SPECTRA API for direct integration into customer systems.

Concentration Map: High-resolution methane plume visualization overlaid on facility infrastructure for screening, review, and operational interpretation.

Emission Rate Estimates: Quantified methane emission rates (kg/hr) derived from derived from plume morphology, concurrent wind data, and reported with associated uncertainty. 

Abundance Dataset Add-On: Per-pixel methane concentration data provided in GeoTIFF format, enabling detailed analytical workflows and advanced modelling. 

Historical Catalog Archive: Access to prior methane observations by region and time period for trend analysis and retrospective performance assessment. 

Independent Methane Monitoring

Purpose-Built Greenhouse Gas Satellite Constellation

DATA.SAT satellites form GHGSat’s dedicated greenhouse gas constellation, engineered specifically for high-resolution, facility-level methane detection at 25 m ground sample distance.

Powered by GHGSat’s patented remote sensing technology—the same sensor adapted for DATA.AIR airborne operations—the constellation delivers independent, direct methane measurements with repeatable global coverage across onshore, offshore, over-water, and snow-covered environments.

GHGSat was the first company to detect and quantify offshore methane emissions from space. The platform also includes CO₂ monitoring capability.

Applications Across Asset Types & Regulatory Contexts

Oil & Gas: Upstream and midstream assets, pipeline networks, offshore platforms, remote and hard-to-access sites 

Mining & Extractive Industries: Surface coal operations, mine vents, extractive facilities 

Waste Management & Landfills: Municipal solid waste sites, landfill gas collection systems, regional waste infrastructure 

Government & Regulators: National emissions inventories, regulatory oversight programmes, cross-jurisdictional monitoring 

Financial Institutions & ESG Teams: Asset portfolios, financed emissions reporting, ESG due diligence 

Case Study | Oil & Gas

Satellite Methane Monitoring Across Industrial Assets

DATA.SAT was deployed to screen SOCAR-operated facilities for methane emissions using high-resolution satellite monitoring. Independent observations identified facility-level plumes and quantified emission rates, providing clear spatial attribution across a distributed asset portfolio.

“GHGSat’s satellite technology is a gamechanger: the high-frequency monitoring, combined with granular data that pinpoints the source of an emission, allows our team to address methane swiftly and effectively. Drawing on this technology, alongside technical expertise from OGCI that ensures effective use of the data, has enabled SOCAR to achieve tangible emissions reductions, strengthening our environmental performance and operational efficiency.”

FAQ

Frequently Asked Questions

What is the difference between DATA.SAT and DATA.AIR?

DATA.SAT provides frequent, wide-area satellite methane monitoring across distributed asset portfolios, identifying where emissions are occurring and at what rate. DATA.AIR provides high-resolution airborne measurement at the facility level, investigating specific sources and attributing emissions to individual components. Within GHGSat’s tiered monitoring framework, DATA.SAT identifies where follow-up is needed and DATA.AIR delivers the source-level precision to act on it. 


What is the difference between DATA.SAT and public satellite data such as Sentinel-5P?

Public satellites like Sentinel-5P detect methane at a regional scale with detection thresholds above 3,000 kg/hr and a spatial resolution of 7 km. DATA.SAT detects at 100 kg/hr at 50% PoD with a 25 m ground sample distance, enabling facility-level attribution rather than regional mapping. DATA.SAT data is also processed, validated, and delivered with documented uncertainty by GHGSat’s analyst team, making it suitable for regulatory submissions and certification workflows where public data is not.


How does DATA.SAT integrate with existing emissions management systems?

DATA.SAT outputs are delivered through SPECTRA, GHGSat’s emissions analytics platform, and customers can pull data directly into their own systems via the SPECTRA API. Data is provided in standard formats including GeoTIFF. GHGSat applies AI and machine learning across the data processing workflow, including automatic plume detection, cloud detection, masking and filtering, and observation prioritization for quality assurance, ensuring data is processed efficiently and consistently before delivery.


Is DATA.SAT data accepted for regulatory frameworks such as OGMP 2.0?

DATA.SAT delivers independent, measurement-based emissions data with documented uncertainty meeting the evidentiary standard required for regulatory submissions. GHGSat data has been used to support OGMP 2.0 reporting and third-party certification programs. Confirm specific framework applicability with the GHGSat team for your jurisdiction and reporting requirements.


Can DATA.SAT monitor offshore and remote assets?

Yes. GHGSat was the first company to detect and quantify offshore methane emissions from space, using a sun-glint measurement approach that enables monitoring of platforms, pipelines, and infrastructure over water. DATA.SAT also supports monitoring across snow-covered and high-latitude environments, extending coverage to assets where conventional inspection methods are logistically constrained.


Does satellite methane monitoring require overflight permissions or access to the facility?

No. Satellite methane monitoring requires no overflight permissions, site access, or coordination with asset owners or national aviation authorities. DATA.SAT observes facilities from orbit, meaning operators receive independent emissions data regardless of site accessibility, geographic location, or airspace restrictions, including offshore platforms, remote production sites, and facilities in jurisdictions where aerial monitoring is subject to regulatory constraints.
