The Regional Deterministic Air Quality Analysis (RDAQA) is an objective analysis of surface pollutants which combines numerical forecasts from the Regional Air Quality Deterministic Prediction System (RAQDPS) and hourly observational data from monitoring surface networks over North America in order to produce a better description of the air quality at every hour. Chemical constituents include 03, SO2, and NO2 gases, as well as fine particulate matter PM2.5 (2.5 micrometers in diameter or less) and coarse particulate matter PM10 (10 micrometers in diameter or less). Geographical coverage is Canada and the United States. Data is available only for the surface level, at a horizontal resolution of 10 km. The products are presented as historical, annual or monthly, averages which highlight long-term trends in cumulative effects on the environment.

The Regional Air Quality Deterministic Prediction System FireWork (RAQDPS-FW) carries out physics and chemistry calculations, including emissions from active wildfires, to arrive at deterministic predictions of chemical species concentration of interest to air quality, such as fine particulate matter PM2.5 (2.5 micrometers in diameter or less). Geographical coverage is Canada and the United States. Data is available at a horizontal resolution of 10 km. While the system encompasses more than 80 vertical levels, data is available only for the surface level. The products are presented as historical, annual or monthly, averages which highlight long-term trends in cumulative effects on the environment.

The Ministry of Environment operates a network of continuous ambient air monitoring stations to measure the concentration of air pollutants across Saskatchewan. This is considered validated data that has undergone quality control and quality assurance. For best results download the entire dataset without filtering as a CSV. ‘Date and time’ as displayed is your local time. However, downloaded data is in UTC for ‘Date and time’. Any values of -9999, -999, or 9980 are invalid data.Download zip file. The Ministry of Environment operates a network of continuous ambient air monitoring stations. These stations are part of the National Air Pollution Surveillance (NAPS) network. Continuous ambient air monitoring stations measure the concentration of air pollutants across Saskatchewan. The data is used to:  • track and report on progress for achieving air quality objectives • measure representative pollutant concentrations and determine long-term trends and • provide air quality information to the public Air pollutants typically come from various industrial activity and natural sources, such as mining, oil and gas, agriculture, forest fires, electrical generation, and the transportation sector. Disclaimer: Hourly data from the Saskatchewan Ministry of Environment monitoring stations is validated and updated every quarter. This is the most up-to-date and accurate information available. A final annual review occurs in spring where data are subject to change.

This dataset contains the validated hourly results of the [Air Quality Index (AQI)] (https://www.iqa.environnement.gouv.qc.ca/contenu/index.asp) and its sub-indices for each station in the [Quebec Air Quality Monitoring Network (RSQAQ)] (https://www.environnement.gouv.qc.ca/air/reseau-surveillance/Carte.asp).The results of the stations in the city of Montreal are not included. To obtain them, consult the dataset [RSQA - air quality index (historical)] ([measured on the island of Montreal] (https://www.donneesquebec.ca/recherche/dataset/vmtl-rsqa-polluants-gazeux)).The IQA is an information and awareness tool designed to inform the population about the quality of ambient air in Quebec.If you have any questions about this data, contact the Info-Air department:.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
