Data Licence Agreement & Disclaimer for Air Quality Data


The data and information has been collected on a near "real time" basis by automated monitors. It is preliminary in nature and has not yet been tested or verified. Therefore, it may be subject to change, without notice, pending subsequent review and verification. At this time, it is provided as a "public service" on an "as is" basis without warranty, whether express or implied, as to its quality, accuracy, suitability, reliability, usability, completeness, timeliness or applicability for particular purposes. The application of quality assurance and verification procedures to the data and information may result in differences between what is currently displayed and what will become the official record.

Missing Data and Instrument Calibration

Instruments that measure O3, NO2, SO2, TRS, H2S, and CO all perform an automated test each day to ensure the equipment is operating properly. These tests take 1 hour to complete. Data are not available (NA) while the equipment test is taking place.

By accessing these datasets, you agree to the licence associated with each file, as indicated in parentheses below.

Data found on the BC Air Quality web site is accessible in raw form before all quality assurance reviews are complete. This data is preliminary and is subject to change during the review process.
