Brad Hall


I received my Ph.D. in 1997 from Washington State University in Pullman, Washington for studies on the dry deposition of hydrogen peroxide. Upon leaving WSU, I worked at the CSIRO in Sydney, Australia for two years, developing a microphysics module for modelling heterogeneous chemistry associated with polar stratospheric ozone loss. I joined the NOAA Global Monitoring Laboratory in 1999 under James Elkins. I currently spend most of my time developing and maintaining calibration scales associated with greenhouse and ozone-depleting gases, and analysing long-term data records of atmospheric trace gases measured by GML. Interests include: the use of SF6 as a tracer of atmospheric transport; the nitrous oxide budget and trends in its atmospheric abundance, impact of the Montreal Protocol on Substances that Deplete the Ozone Layer, and improving methods for analysis and calibration of trace gases.

Outside of work I enjoy fly-fishing and playing volleyball. On many summer and fall weekends you can find me fly fishing with my son on nearby rivers and streams, or hiking to a remote mountain lake to try and entice trout to take an artificial fly.
