Aaron J. Glenn, Ph.D.

Research Scientist

Dr. Glenn’s micrometeorological research directly addresses the Science and Technology Branch science sector strategy on Agroecosystem Resilience which aims to develop knowledge and tools that support sector adaptation to environmental impacts of agricultural production and reducing agriculture’s environmental footprint. His research also responds to the strategic objective of enhancing environmental performance across many agricultural commodity portfolios (e.g. cereals & grains, oilseeds, beef & forage) as it takes place in the context of multi-year temporal and farm-level spatial scales which include a range of crop rotations and integrated crop-livestock production systems.
