Assessing community response to wildfire smoke: A multimethod study using social media.

Objective: The purpose of this study was to assess health-related responses to wildfire smoke on social media. We examined whether seasonal wildfire smoke is an active topic on Twitter, the correlation between fine particulate matter (PM ) and Twitter search terms, and dimensions of community-level expression to wildfire smoke through tweets.

Design: Search terms were identified using a conceptual model developed and refined by healthcare providers and public health experts.
