Special studies data

Measurements of a variety of air pollutants, all at once, we call a special study. Special studies are as short as a few weeks to as long as several years. Regular monitoring, however, is typically longer term (five years or greater for a continuous data record).

Special studies measurements may be at the surface (ground-based), from an aircraft (airborne) or from space (satellite). These measurements help us to understand chemical processes in the atmosphere and better understand air quality.

Typically, many air quality data types are gathered under one topic name to assist researchers in gathering their data sets.

The NAtChem archive contains the following data:

• Borden Forest Ozone and Sulphur Dioxide Dry Deposition Study
• Nitrogen Scoping Study (2001-2005)
• Pacific 2001 
• PANAM 2015 Study
• Shale petroleum extraction emission characterization study (SPEECH)
