Haze/Visibility Planning

Supporting the Use of Satellite Data in Regional Haze Planning


This HAQAST Tiger Team proposes to work with stakeholders to address three applications of satellite data of direct relevance to regional haze State Implementation Plans (SIPs). The team will develop technical guidance documents that describe their approaches to using satellite data for regional haze applications. We anticipate that the guidance developed under this project will also be relevant to health agencies seeking to assess health burdens due to natural events (e.g., dust, wildfires) associated with severe health effects. In addition, they’ll aid air quality managers in the use of satellite data in the Regional Haze SIP process, provide tangible examples of the value of satellite data for addressing air quality and related health applications, to aid stakeholders who wish to conduct their own analyses, and lower the barrier for new health and air quality stakeholder agencies to apply satellite data.
