Hourly air pollution and meteorology variables from the LADCO Winter Nitrate Study and the SEARCH network (Jefferson St. Atlanta and Yorkville GA sites), in support of the LADCO Winter Nitrate Study

From the Background section of the LADCO Winter Nitrate Study (WNS) Phase I report, Stanier et al. (2010). "From December 2008 to March 2009, an intensive monitoring campaign was conducted by ARA Inc., the Wisconsin DNR, the Illinois State Water Survey, and LADCO. Continuous measurements of ammonia, ammonium, nitrate, nitric acid, ozone, NOx, NOy, and meteorology were conducted at an urban site (Milwaukee, Wisconsin), and an upwind rural site (Mayville, Wisconsin). Integrated samples of many species were also collected. Analysis of the study data was conducted by researchers from the University of Iowa and the University of Illinois. The analysis also included data from similar instruments at an urban-rural pair in the South Eastern Aerosol Research and Characterization (SEARCH) network around Atlanta, Georgia. Hourly inorganic species from both the SEARCH network and the Winter Nitrate Study are taken by the iCAMS (Inorganic Continuous Aerosol Measurement System), which is described in section 3 and in Appendix 2."
