Dr. Arain is a professor in the School of Geography and Earth Science and an associate member of the Department of Civil Engineering at McMaster University, Hamilton, Ontario, Canada. He is also the Director of the McMaster Centre for Climate Change and Associate Director of the School of Geography and Earth Science. He is the president of the Canadian Geophysical Union (CGU) – Biogeosciences Section. He holds a Bachelor Degree of Civil Engineering (1987) and Master of Science and Ph.D degrees in Hydrology. Dr. Arain’s research interests focus on bio- and hydro-meteorology, hydrology, climatology, air pollution, land surface-atmosphere interactions, and climate modeling. He has expertise in both micrometeorological measurements and ecosystem modeling.
His Turkey Point energy, water, and carbon flux tower sites in an age-sequence of planted/afforested pine forests near Lake Erie in southern Ontario are part of the Canadian Carbon Program (CCP) and global Fluxnet. He developed the carbon and nitrogen coupled Canadian Land Surface Scheme (CN-CLASS) and Canadian Terrestrial Ecosystem Model (CTEM-N+) models. CN-CLASS model development work was part of a multi-university collaborative modeling initiative known as the Canadian Global Coupled Carbon Climate Model, (CGC3M) to develop a global coupled carbon climate model. Coupling of CTEM- N+ in the Canada General Circulation Model (CGCM) will provide an assessment tool to generate scenarios of future climate for policy development conducted by organizations such as the United Nations Intergovernmental Panel on Climate Change.
He has focused on using meteorological and nitrogen dioxide data to improve land use regression models for health studies in urban settings. He has published more than 65 refereed journal papers.
