Sunlight & UV Indicators

The Tracking Network has data on the following indicators.

Sunlight Exposure

This indicator provides state and county level data on monthly and annual average exposure to sunlight.

UV Radiation Exposure

This indicator provides state and county level data on monthly and annual average doses of UV measured daily and at noon.

These indicators can be used to:

  • Understand how solar radiation levels are changing across geography and time.
  • Identify areas where intensity may be increasing.
  • Provide data to help public health officials make informed decisions about planning and implementing programs and services for people living in regions of high exposure.

Solar Radiation Data

In addition to viewing data through the Data Explorer, you can access complete datasets of county-level radiation exposure data from the Tracking Network’s Downloadable Datasets page.
