The contents of the site www.jsirwin.com has been relocated to this url, www.harmo.org/jsirwin/
The author of the site, John Irwin, passed away in 2016. The data archives he compiled are retained here, largely as he created them.
Additional information about the transferred site...
There are existing data from past tracer and meteorological field experiments that, as yet have not been fully converted to digital format.
This web site is my attempt to provide such data sets I have for use by others.
Many of these data sets, which were initially used to develop or test parameterizations for Atmospheric Transport and Diffusion (ATD) models, can yield additional, valuable results, for example, on concentration uncertainty and short-term fluctuations in concentration values.
I believe available data sets should posted on the web for access and use by the research community. It seems to me to be more cost-effective to archive and re-analyze these data sets than to repeat the underlying field studies at great expense.
If you publish analyses using data from this site, I would appreciate a citation to inform others about the content of this web site, for instance: "Data were downloaded from www.harmo.org/jsirwin".
