Daily Measurements at the Gold Bar Park Air Quality Monitoring Station

This data comes directly off our computerized air quality monitoring system and has not been validated. Please use it as a guideline only. For verified monthly data, see the list of downloadable reports.

1. Alberta Ambient Air Quality Objectives

Alberta’s ambient air quality objectives (AAAQOs) and guidelines are developed under the Alberta Environmental Protection and Enhancement Act (EPEA). Objectives are developed to protect Albert​a’s air quality. The 24-hour average AAAQO for H2S is 3 parts per billion (ppb).

2. Wind Speed

Wind speed is caused by air moving from high to low pressure, usually due to changes in temperature or other local effects. Lower wind speeds generally mean less dispersion of air, potentially resulting in localized higher concentrations of elements. Higher wind speeds disperse air faster and over a wider area.

3. Wind Direction

Wind direction is reported according to the direction from which it originates – for example, a north wind blows from north to south. Winds are usually reported using either cardinal directions, or degrees of direction.​

4. Temperature

Air temperature affects the movement of air. Different temperatures between two locations create a difference in air pressure. The atmosphere tries to equalize the air pressure, forming wind.

5. Relative Humidity

Humidity is the concentration of water vapor present in the air. Relative humidity is the ratio of a present state of humidity relative to a maximum humidity given the same temperature.

6. Barometric Pressure

Barometric pressure is the air pressure, as measured within the atmosphere. It is quantified by the hydrostatic pressure caused by the weight of an air column above a measurement point. It is impacted by the planetary rotation and local effects such as, variations in temperature, density, air composition etc. Wind is generated by air movement from high to low pressure areas. ​​

Ambient Air Quality Mo​nitoring Station ​​reports

The Gold Bar Park station, near the Gold Bar Wastewater Treatment Plant, continuously monitors ambient air quality. This data is published on our website on the 15th of each month. Please see the monthly reports below.​
