Project Overview

The goal of APMAC is to create remote sensing data sets at regional scale that directly constrain the methane emissions for important source regions. The MethaneAIR and HALO instruments will be utilized on the G-III, and coincident observations by the MethaneSAT satellite, with repeated surveys of the same region two-day periods, to create uniquely data-rich, comprehensive observations of methane concentrations and their changes over time that can fully constrain regional emission rates. The goal is to deliver three "Benchmark datasets" at regional scale, rich in remote sensing observations, where the emissions can directly be constrained in time and space within narrow limits. These datasets will enable rigorous testing of the accuracy of the inverse models used to quantify regional emissions, providing validation, and enhancing credibility for methane emission assessments based on remote sensing.
