he AirData website gives you access to air quality data collected at outdoor monitors across the United States, Puerto Rico, and the U. S. Virgin Islands. The data comes primarily from the AQS (Air Quality System) database. You can choose from several ways of looking at the data:download data into a file (or view it on the screen)output the data into one of AirData’s standard reportscreate graphic...

The Air Quality Annual Statistics Viewer shows yearly data for all 12 air pollutants that have legal limits under EU air quality laws. Results are presented by year on maps and box plots. Specific screens also show the evolution throughout the years, as well as the distribution of the values...

Status of reporting under the Air ConventionParties to the Air Convention are invited to report annual emission data by 15th of February and informative inventory reports (IIRs) by 15th of March. The overview tables (see 20YY submission)  for individual years present most recent data as submitted to the Air Convention in that year.Initial and extended checks (S1 and S2)The inventories (NFR ta...

Low-cost sensors collect large amounts of data. Some sensors distributed through the US EPA STAR Grant program have beenrunning continuously for over a year, recording data every minute (that’s over 500,000 rows of data!). For this reason dataanalysis tools and software can be very helpful. In this guide we provide some brief instructions to help community scientistsinteract with the data they are...

Air pollution has reduced steadily across Europe over recent decades, yet it remains the region’s largest environmental health risk, causing diseases, lowering quality of life and leading to preventable deaths. The EU has set air quality standards to reduce risks posed by air pollution. This report presents analysis of the latest official 2023 and 2024 reported concentrations in Europe against cur...

This annual report on air quality in the Paris region covers trends, spatial distribution, and compliance with air quality standards for criteria pollutants. It also analyses population exposure, health implications, and projections under revised European directives....

The intent of this document is to provide guidance to assist auditors in implementing the Technical Systems Audit (TSA) requirements and to provide guidance and tools to aid in conducting TSAs of ambient air monitoring programs. While this document is geared primarily for federal auditors conducting TSAs of air monitoring programs required by CFR, the principles and tools provided in the document ...

This worksheet (Monitor data processing guide for PM10, PM2.5, NO2, SO2, CO) is an annex to the "Ambient air quality data processing and reporting guide" developed by C40. It can be used to analyse your own data to develop averaging metrics:Daily (24-hour) means (for PM10, PM2.5, NO2, SO2, CO).Monthly means (for seasonal variations of pollutants).Annual means (for PM2.5, PM10, NO2)....
