Air quality impacts us all.  The air we breathe is full of particles that come from factories, cars, construction sites, and many other sources. These particles can get into our lungs and even our bloodstream to cause serious health issues. Organizations such as the Environmental Protection Agency (EPA) and NASA provide information about the air we breathe in order to provide a data-driven approach for regulations and guidelines. ArcGIS Living Atlas of the World contains a wide range of layers, maps, and stories that help communicate what air quality in the US was like in the past, and how it is currently.  There are many different ways to explore air quality with content from ArcGIS Living Atlas of the World. A few of those ways are: Current Air Quality Air Quality Index (AQI) by the Environmental Protection Agency (EPA) and AirNow "The AQI is divided into six categories. Each category corresponds to a different level of health concern. Each category also has a specific color. The color makes it easy for people to quickly determine whether air quality is reaching unhealthy levels in their communities." - AirNow Find all EPA layers, maps, and applications in Living Atlas by clicking here. Current PM 2.5 concentrations The OpenAQ Community reports recent PM 2.5 concentrations  Every day activities such as driving, burning coal for electricity, wildfires, running factories, even cooking and cleaning, release particles into the air. Besides being an irritant, small particles of 2.5 micrometers or less (PM2.5) are a health hazard since they can get deep into the respiratory system and damage the delicate tissues. Smoke Forecasts National Weather Service 48 hour forecast Forecasts of smoke can help us protect vulnerable populations from potential health risks. Historical PM 2.5 concentrations NASA's Socioeconomic Data and Applications Center (SEDAC) 1998-2016 PM 2.5 values were analyzed over space and time at the state, county, congressional district, and 50 km hex bin levels in order to investigate trends and statistical hot spots.

There are many reasons you might need to access the item ID for content items within ArcGIS Online. The item ID is the basis for many automation and mapping techniques used within the ArcGIS REST API, the ArcGIS JavaScript API, and ArcGIS API for Python. The item ID is also a great way to search for items within the ArcGIS platform, because it will always bring you to the exact item you need. But where can you easily find this item ID? The easiest and fastest way to access the ID is from the ArcGIS Online content item details page. For example, here is the item details page for a web map named "Population Not in the Labor Force" The item ID may not be immediately apparent, but its actually in a very easy place to find. If you look at the URL, you can see the ID at the end after ?id= The above example shows a web map item in ArcGIS Online. However, if you wanted to find the item ID for one of the layers in the map, you can also do that from the item details page. Find the Layers section, click on the layer of interest, and view the item ID in the address bar. Easy tip: if you double click the ID within the URL, it will highlight just the ID (as seen in the gif above) ... View more
