On State level, this tool shows number of power outages between 2000 and Sept. 2015. You can limit power outages by season, e.g., summer only.

On county level, this tool shows CDC DAILY TEMPERATURE in the base layer, you can use either maximum temperature, minimum temperature or extreme temperature (defined as above 90% percentile) to render the counties. You can turn on/off EPA DAILY NO2 layer (highlighted in \) and/or EPA DAILY OZONE layer (highlighted in /) and/or NDSSL SOCIAL ISOLATION layer (highlighted in —) by checking on/off the checkbox to explore correlation between layers.

For any layer, you can use the range slider to view a subset of data that has value in the selected interval.
