This layer displays the daily average concentration of fine particulate matter and the percentage of days with concentrations of fine particulate matter above the National Ambient Air Quality Standard (NAAQS) of 35.0 micrograms per cubic meter in 2018.
Air Quality – Daily Concentration, Particulate Matter (PM 2.5) by County, 2017
This layer displays the daily average concentration of fine particulate matter and the percentage of days with concentrations of fine particulate matter above the National Ambient Air Quality Standard (NAAQS) of 35.0 micrograms per cubic meter in 2019.
Air Quality – Ozone Levels (O3) by Census Tract, 2016
This layer displays the daily average concentration of ozone and the percentage of days with concentrations of ozone above the National Ambient Air Quality Standard (NAAQS) of 0.075 parts per million in 2016.
Air Quality – Fine Particulate Matter (PM2.5) by Census Tract, 2017
This layer displays the daily average concentration of fine particulate matter and the percentage of days with concentrations of fine particulate matter above the National Ambient Air Quality Standard (NAAQS) of 35.0 micrograms per cubic meter in 2017.
Air Toxics – Cancer Risk by Census Tract
Layer displays the modeled cancer risk associated with air toxics exposure. Figures represents the likelihood of hazardous exposure per 1 million population.
Air Toxics – Non-Cancer Risk by Census Tract
Layer displays the modeled non-cancer risk associated with air toxics exposure. A hazard index (HI) of 1 or lower means air toxics are unlikely to cause adverse noncancer health effects over a lifetime of exposure.
30-Day Hospital Readmission by County, 2020
This layer displays the percentage of Medicare inpatient readmissions within 30 days of an acute hospital stay during then reference period.
30-Day Hospital Readmission by County, 2019
This layer displays the percentage of Medicare inpatient readmissions within 30 days of an acute hospital stay during then reference period.
Drought Intensity, U.S. Drought Monitor
This layer displays areas that experienced dry or drought conditions in the last seven days. Data are retrieved as shapefiles from the U.S. Drought Monitor and are updated on a weekly basis. The affected areas are represented by polygons, which are classified according to drought intensity. Using quantitative and objective indicators, as well as local condition and impact reports, the U.S. Drought Monitor defines each drought intensity level as follows:
D0 – Abnormally Dry
D1 – Moderate Drought
D2 – Severe Drought
D3 – Extreme Drought
D4 – Exceptional Drought.
For more information about the data, please see the U.S. Drought Monitor Data Classification web page.
Air Quality – Fine Particulate Matter (PM2.5) by Census Tract, 2012
This layer displays the percentage of days with concentrations of ozone matter above the National Ambient Air Quality Standard (NAAQS) of 35.0 micrograms per cubic meter.
