This past summer, researchers across the UK and India are teaming up to study the Indian monsoon as part of a £8 million observational campaign using the NERC research aircraft BAe-146. India receives 80% of its annual rainfall in three months – between June and September. There are large year-to-year differences in …
In parallel with efforts to create a detailed bottom-up inventory (National Atmospheric Emissions Inventory) for the major greenhouse gases, the UK has funded four monitoring stations to infer emissions for the purposes of verification. In our new study, available on Atmospheric Chemistry and Physics Discussions, we have used two years …
One of my main research interests is in measuring the concentrations of greenhouse gases in South Asia, an area that holds significant implications for global climate and climate policies. Despite its importance, this region of the world is poorly monitored by global atmospheric monitoring networks. In 2011, collaborators from the …
The electron capture detector was installed in Darjeeling in March 2012. Measurements of N2O and SF6 are underway and 4 months of CH4 have already been collected!
My instrument was deployed to Darjeeling in November 2011. Measurements of CH4 are currently underway! The installation of the ECD is expected in spring 2012. More information and pictures about the deployment can be found here!
Atmospheric methane (CH4) and (N2O) are major long-lived greenhouse gas and have the second and third highest radiative forcing after carbon dioxide (CO2). A positive radiative forcing means that the atmosphere is being warmed, while a negative forcing means that cooling is occur. All greenhouse gases have a positive radiative forcing …
