How this service works
Sums enhancement_ppm×pixel_area, multiplies by wind speed, plume orientation, and a caller-supplied conversion factor, and reports the resulting proxy and optional kg/h estimate. It does not retrieve satellite data, remove background, solve atmospheric transport, determine source location, or validate the conversion factor.
Output
Returns a unitless methane flux proxy (sum of enhancement_ppm × pixel_area, scaled by wind speed and plume orientation factor) and, if a nonzero conversion factor is supplied, an estimated emission rate in kg/h. Does not include retrieved satellite imagery, background removal, atmospheric transport modeling, source localization, or validation of the conversion factor.
Example use cases
Oil field methane leak quantification
“I've extracted 1,200 satellite pixels over a natural gas facility — each has a methane enhancement in ppm and pixel area. Wind speed is 6.2 m/s, plume orientation factor is 0.75, and my conversion factor is 5.5e-7. Can you calculate the total emission flux proxy and the estimated kg/h leak rate?”
Pipeline monitoring emission estimate
“We're monitoring a pipeline corridor and have 300 satellite pixels flagged with methane enhancement values and areas. Use a wind speed of 3.1 m/s, a plume orientation factor of 0.6, and conversion factor 7.2e-7 to get me the methane emission rate in kg/h.”
Unitless proxy only for anomaly screening
“I just want the unitless emission proxy — no kg/h estimate needed — for 80 satellite pixels from our methane screening pass. Wind speed is 5.0 m/s, plume orientation factor 0.9, and set the conversion factor to zero.”
Technical details
Endpoint
POSThttps://space.halowerk.com/v1/methane-leak-satWhen to prefer
Use this endpoint when you have already preprocessed satellite pixel data (enhancement values and areas extracted, background removed) and need a fast, cheap arithmetic aggregation into a methane flux proxy or kg/h estimate. It is not suitable when you need to fetch raw satellite imagery, perform atmospheric retrieval, remove background noise, or determine source location — those steps must be completed upstream. Prefer this over building the integration manually when working in an agentic pipeline that chains satellite preprocessing with quantification.
Side effects
- Missing required pixel fields (pixel_id, enhancement_ppm, pixel_area_m2) returns validation error
- Pixel array empty or exceeding 100,000 items returns schema error
- Wind speed, conversion factor, or plume orientation factor out of allowed range returns validation error
- Plume orientation factor outside [0,1] rejected
- Conversion factor of zero returns proxy only with no kg/h value
- Invalid numeric types for any field cause request rejection
