The environmental data available on CDC WONDER are county-level daily measures of air temperature (degree days), heat index, land surface temperature, outdoor air quality (fine particulate matter) and sunlight (insolation or solar irradiation). Data are available by place (combined 48 conterminous United States, region, division, state, county), time (year, month, day) and specified measure value. This work was part of a collaborative study funded by the NASA Applied Sciences Program/Public Health Program (grant# NNX09AV81G).
