One can use this application to get more information about the air quality and visualize the data. The user can choose they year and pick the state and the county accordingly to see various graphical representations. The user can also choose to to view annual, daily or hourly data that will show the AQI data and individual pollutants, various annual and daily data visualization and even location of the chosen selection.
Here are the steps on how to get the most out of the application:
Upon loading the site, you will be greeted with a blank web page.
After selecting the Year, State, County and Annually as the data representation option, charts and graphs showing the data for the selected year, state, and county will be shown:
To show charts and graphs representing the daily AQI data, select the Year, State and County, as well as Daily as the data representation option. Here you can see Daily AQI levels for the Year and county selected, the most prominent pollutant for each day, and AQI levels per month:
- If the page shows graphs and charts without data, it is because daily data files have much bigger file sizes than annual data, so you might have to wait for a few seconds to allow the system to visualize the data.
To show graphs representing the hourly AQI data, select the Year, State and County, as well as Hourly as the data representation option. Here you have to pick the specific date from the calendar to show the data for that date (dates without data will not be available for selection). After selecting the date, an empty line graph will show:
- Same for the daily data, the calendar might now be visible immediately. This is also because hourly data files have much larger file sizes than annual and daily data. Allow the system to visualize data, and after a few seconds the calendar should appear.
To show the hourly AQI data from the line graph, select the pollutant/s you would like to see on the Line graph by ticking the checkboxes of the selected pollutants. After selecting pollutants, data will now appear on the line graph:
Our system could also provide a map with the Top Counties with worst pollution, given a specific pollutant. To see this map, select a Year and a pollutant from the side bar, as well as Relative Badness as the data representation option with the worst counties having a deep RED shade and counties with better pollution levels having light yellow shades. By default, this will show the Top 100 Counties with worst pollution given your selected pollutant:
If needed, you could also select the number of counties to show on the map. Adjust the slider to increase or decrease the number of counties visible on the map:
