This is USDA-ARS data from the publication, "Characterization of particle size distributions and water-soluble ions in particulate matter measured at a broiler farm." This study was conducted in June of 2018. Data included here are from several measurements:

1. Gas-phase ammonia measurements measured by an electrochemical sensor (Cairpol) in part-per-billion (ppb) with 1 minute time interval.
2. Particle number concentration inside and outside the house measured by two optical particle counters (MetOne) in number per cubic centimeter (mg/cc) with 20 second interval. Particles were measured from 0.5-10 micrometers in 8 size bins.
3. Particle number concentration measured by a scanning mobility particle sizer (TSI) and given as the differential number per size bin over 80 bins from 10-500 nanometers with a 5 minute time interval.
4. Water-soluble ions in particulate matter measured by an ambient ion monitor (URG) measured in microgram per cubic meter with a 1 hour time interval.
