Toward Quantifying Area-fugitive Greenhouse Gas
(GHG) Emissions from Open-pit Mines

– By Amir Nazem, Md. Rafsan Nahian, Ryan Byerlay, Manoj K. Nambiar, and Amir A. Aliabadi-

Conventional techniques to quantify area-fugitive Greenhouse Gas (GHG) emissions from an open-pit mine have serious drawbacks. The bottom-up approach is based on inventory estimates, in which the emissions from different stationary sources across a mining facility are combined. This approach does not include the atmospheric measurements of GHGs or meteorology and relies on assumptions of the strength of each GHG source within a facility that may not be up-to-date.

MOPITT – Measuring Pollution in the Troposphere for 20 Years

– By Prof. James R. Drummond, FRSC, Department of Physics & Atmospheric Science, Dalhousie University –

Most scientific projects run for a few years and then the people involved move on to something else. The Measurements Of Pollution in The Troposphere (MOPITT) project has been running for over 30 years and on December 18th, 2019 we are celebrating the 20th anniversary of the launch of the MOPITT satellite instrument.

Media reports around the world have highlighted the extreme and unprecedented nature of wildfires in recent years (e.g. Chile 2017, Portugal 2017, Greece 2018, California 2017 and 2018). In Canada, the 2016 Fort McMurray wildfire was the third largest in Alberta’s history and became the costliest natural disaster in Canadian history,

Using Back-Trajectories to Trace the Origins of Fine Particulate Matter (PM2.5)

– By Jean-Philippe Gilbert, Richard Leduc, and Nathalie Barrette, Geography Department, University of Laval

Air pollution in the province of Québec, Canada is monitored daily to allow for a rapid response to public health issues. However, there are few studies concerning the long-distance trend of pollutants, and those studies that do exist focus on a small area of study. The objective of this paper is to determine the sources of certain pollutants coming in to Québec,

MOPITT, Atmospheric Pollution, and Me: A Personal Story

– By Jim Drummond, Principal Investigator for the Measurements Of Pollution in The Troposphere (MOPITT) instrument on the Terra satellite –

It’s 1987 and I have just bought my first personal computer – an IBM PC clone running at a stunning 8MHz! I’m also on sabbatical at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado,
