NASA has published the first maps from its new space-based pollution instrument, TEMPO (Tropospheric Emissions: Monitoring of Pollution). Although you won’t be shocked to learn it reveals higher pollution rates in metropolitan areas, the tool can help scientists better study North American air quality on an hourly basis. “Neighborhoods and communities across the country will benefit from TEMPO’s game-changing data for decades to come,” NASA Administrator Bill Nelson wrote in a press release today.
