Constraining Annual Coal Mine Methane Emissions with Multitemporal Hyperspectral Satellite Observations

Methane emissions from coal mining are difficult to constrain because of temporal variability and sparse observations. We used multitemporal hyperspectral observations from GF5A, GF5B, ZY1E, and ZY1F to quantify facility-scale emissions and evaluate sampling requirements for annualized estimates. Of 301 scenes acquir...
