Health and Environment Linked for Information Exchange, Atlanta (HELIX-Atlanta).

Linkage of Environmental and Health Data

Two sources of environmental data for HELIX-ATLANTA:
  1. U.S. EPA Air Quality System (AQS): Daily PM2.5 measurements
  2. NASA EOS Data Gateway: MODIS Aerosol Optical Depth (AOD), used to estimate ground-level PM2.5 concentrations.

Processing, Linkage and Data Exchange

  • The environmental data (PM2.5) are linked to the health data (acute asthma office visit data) provided by Kaiser Permanente of Georgia (KP-GA).
  • The linked data that includes individual health information are sent from NASA to KP-GA for further analysis.
  • The linked data are aggregated into surfaces of 10 km by 10 km resolution that will protect the privacy and confidentiality of KP-GA health members.
  • The aggregated data set are sent back to the CDC and published for the public.
