Major ions data consist of the following key ions in precipitation: Cl-, NO3-, SO4=, NH4+, Na+, K+, Ca++, Mg++. The data sets typically also include the pH and depth of the precipitation sample. These data are collected by several provincial, national and bi-national networks. The wet-only...

These data are associated with the following two publications: Zhiyong Wu, Staebler R., Vet R., and Zhang L. (2016), Dry deposition of O3 and SO2 estimated from gradient measurements above a temperate mixed forest. Environmental Pollution, 210, 202-210, DOI: 10.1016/j.envpol.2015.11.052 and...

Systematic air quality measurements were made in the study region of Toronto during the 2015 Pan-Am games (July 14th – July 29th). These measurements were done using the mobile lab CRUISER (Canadian Regional and Urban Investigation System for Environmental Research) to identify emission sources...

The atmospheric monitoring subcomponent of the Northern Contaminants Program (NCP) studies long-range transport of anthropogenic organic pollutants in air (AOPA), mercury, and chemicals of emerging arctic concern from around the globe. This subcomponent includes three NCP Core Monitoring...

Precipitation samples are collected at a number of sites in Alberta by Alberta Environment and Parks. Samples are analyzed for select cations and anions as well as pH. Samples are collected weekly using an event-only precipitation sampling protocol. The specific monitoring objectives are to: (1)...
