Manvendra Dubey is the guest speaker at the Los Alamos Geological Society’s (LAGS) monthly meeting at 7:30 p.m., April 21 at Christian Church, 92 East Road in Los Alamos.
Dubey is a scientist and Climate Focus Lead at Los Alamos National Laboratory. He will present the talk, “Methane Hot Spot In Four Corners: Where Is It coming from? Why Does It Matter?”
Methane is 25 times more potent gas than carbon dioxide and its production has increased dramatically from advanced mining and extraction technique. This offers both opportunities and challenges for the US. My talk will summarize our recent discovery of the methane hot spot in the Four Corners area from ground and satellite observations.
Our analysis implicates fossil fuel activities in the region, in particular coal bed methane production. I will discuss a follow up airborne and ground based campaign that is aimed at locating and fingerprinting the methane sources in the region.
Dr. Dubey is Scientist 5 at LANL where his research integrates field observations, laboratory measurements, and models to improve predictions of climate change for ~18 years. He leads the climate observations program in the DOE Office of Science, climate project at the Institute for Geophysics and Planetary Physics and Signatures; climate science research combining multi-scale measurements and models of green house gases and aerosols to enhance projections.
Dubey was instrumental in deploying a verification test-bed for multi-scale greenhouse gas observations and satellite validation in the Four Corners region of the Southwest that is now relocated to Brazil to monitor the rainforest. He has participated in more than a dozen field campaigns spanning the globe to measure the black and brown carbon particles responsible for warming and air pollution.
Dubey has published extensively (80 papers), co-edits the journal Atmospheric Chemistry and Physics, served as an associate editor of Geophysical Research Letters. DOE selected him as a promising atmospheric chemist in 1995 as a Fulbright Scholar in India by Department of State in 2012-2013. Dubey received his doctoral degree from Harvard, where he helped establish the causal link between chlorofluorocarbons and the Antarctic ozone hole.
