This is a measure of the rain accumulated at various rain gauges throughout the City during the rain season, which typically runs from May 1- Sep 30. Readings are taken at 5 minute intervals, and updated daily.
This data is QA/QC'd on an annual basis at the end of the calendar year at which time some adjustments may be made to the data. Users should keep in mind that data viewed before March 31 of the following year should be considered in a ‘raw’ state and may be subject to change

This dataset makes historical air quality data accessible for various parameters at Calgary monitoring stations. The data is collected by the Calgary Region Airshed Zone and submitted to Alberta Environment and Parks (AEP). The data is delivered to the airdata warehouse, a central repository for Alberta's ambient air quality data via a web service provided by AEP. In this way, AEP provides access to quality controlled historical air quality data at its air quality stations.
In addition to air quality monitoring data, an Air Quality Health Index (AQHI) is calculated hourly at certain monitoring stations. The AQHI is a simple way to interpret air quality conditions: it provides a number from 1 to 10+ which indicates the relative health risk associated with local air quality. The higher the number, the greater the health risk. Further information on the AQHI calculation is available at: https://www.alberta.ca/air-quality-health-index--calculation.aspx

An extent of land covered by, intermittent and permanent, water bodies and watercourses. This includes both parcel bounding and non-parcel bounding occurrences. Includes the natural watercourses as follows: Bow River Elbow River Nose Creek West Nose Creek Fish Creek. This is a generalized version of the data set and is intended for cartographic purposes and faster drawing time.

Administrative grouping of Habitat polygons into Natural areas maintained by Calgary Parks or located on lands under Calgary Parks Stewardship.

Information about Calgary's urban forest, including the locations and types of trees on public land. To learn more, visit the Urban Forest Management map.

These maps provide landfill setback information as defined under the Municipal Government Act (MGA) Subdivision and Development Regulation (SDR) Landfill Setback (Section 13) from a City of Calgary Landfill or Waste Management Facility (WMF). The file contains the landfill setbacks for the following City of Calgary Landfills: East Calgary WMF, Shepard WMF, Spyhill WMF, Blackfoot Landfill, Highfield Landfill, Manchester Landfill, Nose Creek Landfill, Ogden Landfill, and Springbank Landfill. For more detailed information on the landfill setbacks, contact Waste & Recycling Services.

Identifies the plant communities and environments within the Natural areas maintained by Calgary Parks or located on lands under Calgary Parks Stewardship.

Depicts basic components of The City of Calgary's 2007 Environmental Reserve (ER) Setback Guideline policy, including the base setback based on stream order, and the additional setback modifier based on slope. This can be used as a starting point to scope out riparian-associated ER requirements for planned future developments. It can also be used within existing built areas of the city to highlight past lost ER opportunities.

This data set contains the community-wide greenhouse gas emissions over time. The emissions are broken down by sector (e.g. transportation, waste, etc.), and by emissions source (residential buildings, commercial buildings, on-road transportation, etc).
