as well as the phase I and phase II LADCO WNS reports as appopriate.

The data file contains hourly observed data for the LADCO Winter Nitrate Study, compiled by Charlie Stanier and colleagues. The intensive monitoring campaign ran from January 1, 2009 - March 31, 2009. It involved hourly time resolution inorganic particles and gases (and other variables) at four sites: Milwaukee, WI; Mayville, WI; Yorkville, GA; and Atlanta, GA.

Please use these data for model evaluation and other research purposes. Please cite Stanier et al. (2012) as noted below and the LADCO reports listed below as appropriate.

A list of measured variables for one of the cities is:

Date, Time

Hourly variables

PM2.5, SO4, NO3, NH4, HNO3, NH3, temperature, wind speed, wind direction
Dewpoint, NOy, O3, RH, Episode designation flag, NO, NO2

visibility, web and dry bulb temperatures, dew point, temperature, RH, rainfall, and pressure from a nearby NWS station

5th and 95th percentile confidence intervals on adjusted inorganic gases and particles after regression calibration of hourly measurements to 24-h filter packs and denuders

24-h variables (mainly 1 in 3 day): PM2.5, NO3, NH4, EC, OC, HNO3, NH3
