Tool for Recording and Assessing the City Environment (TRACE)
Satellites have been collecting petabytes of data on atmospheric composition since 1979, yet there is limited use of this data in informing air quality policy. Here we reduce barriers to its use by policymakers by developing a tool to convert large and cumbersome satellite observations of atmospheric composition into useful information about air quality in cities throughout the world. This provides vital information about the efficacy of policies and impact of their absence on air pollution that is impossible to obtain even in cities where there is a dense monitoring network.
