Abstract
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."
These 4 files have the hourly and 24-h chemical and meteorological data. There is one file for each site. Mayville, WI; Milwaukee, WI; Yorkville, GA; Atlanta, GA. After hosting of the reports and data at LADCO for many years, they were transferred (with LADCO approval) to the University of Iowa Research Online which is better suited for permanent archives of reports and data, being more widely discoverable, issuing a unique DOI, etc.

- Grant note
- This work was supported by LADCO (Lake Michigan Air Directors Consortium), and EPRI (Electric Power Research Institute). LADCO supported the Winter Nitrate Study through measurement contracts, and then through a data analysis contract with the University of Iowa (Stanier as PI). The Southeastern Aerosol Research and Characterization (SEARCH) network was a long term monitoring network operated, in part, by Edgerton, and funded, in part, by EPRI.

- Description methods
- A methodological overview is contained in Stanier et al. Atmos. Chem. Phys. (2012) as cited in the readme. For example, it lists the EPA parameter code for EPA reference method measurements and gives an overview of other measurements done by ARA during the field study, such as the 1-h inorganic aerosol and gas measurements, and the 24-h denuder measurements of HNO3 and NH3 done by the Illinois Soil and Water Survey. Additional methodological information on the ARA measurements can be found in Edgerton et al. (2006) JAWMA as cited above. Many plots and statistics of the data can be found in the LADCO Winter Nitrate Study phase 1 report (Stanier et al. 2010, citation and DOI in readme). Details on the statistical correction of 1-h data to match 24-h (to the extent possible) and assign confidence intervals are in Stanier et al. 2010.
