Quantifying Climate Feedbacks from Abrupt Changes in High-Latitude Trace-Gas Emissions
During the three-year project period, Purdue University has specifically accomplished the following: revised the existing Methane Dynamics Model (MDM) to consider the effects of changes of atmospheric pressure; applied the methane dynamics model (MDM) to Siberian region to demonstrate that ebullitio...
