Monitoring, Understanding, and Predicting the Growth of Methane Emissions in the Arctic Open

Ray Bambha, B. W. LaFranchi, Paul E. Schrader, Erika Roesler, Mark A. Taylor , et al. · 2019

Concern over Arctic methane (CH₄) emissions has increased following recent discoveries of poorly understood sources and predictions that methane emissions from known sources will grow as Arctic temperatures increase. New efforts…

Estimating Regional Methane Emissions Through Atmospheric Measurements and Inverse Modeling Open

Cosmin Safta, Ray Bambha, Hope A. Michelsen · 2019

In this report we describe an enhanced methodology for performing stochastic Bayesian inversions of atmospheric trace gas inversions that allows the time variation of model parameters to be inferred. We use measurements of methane atmosphe…
