NASA Maps Reveal #Toxic #Emissions Over Major #US Cities

by Adam Kovac, August 24, 2023

"NASA’s new space-based air pollution monitoring system has sent back its first maps, showing #CarTraffic brings down air quality in several #MajorCities.

"The six maps were made from data from the Tropospheric Emissions: Monitoring of Pollution (#TEMPO), which launched in April. In scans taken over a six-hour period on August 2, high concentrations of #NitrogenDioxide, a toxic #pollutant tied to car and #smokestack emissions, can be seen hovering over #NewYork, #LosAngeles, #LasVegas and #WashingtonDC.

"While the location of #AirPollution shown in the maps isn’t surprising, the data is only the tip of the iceberg for TEMPO, the first space-based instrument designed to continuously monitor air quality over #NorthAmerica. TEMPO principal investigator Kelly Chance said there are currently 50 scientific studies under way that will make use of data generated by the program. The program will truly get underway in October when the instrument will begin transmitting hourly daytime scans."

"..now, the country’s climate-friendliest mode of transportation besides walking is at risk, as national lawmakers slash the budget for bike lanes – and Filipino #cyclists are organizing to ensure that the silver lining in the #pandemic leads to lasting improvements in #BicycleInfrastructure." #Philippines

Can #MetroManila’s #CyclingBoom survive a return to #CarTraffic?

In #Detroit, the day before #Thanksgiving is a red-letter day for the #bike community. The three-mile-long #Parade Route on #Woodward Avenue is closed to #CarTraffic and is temporarily #pedestrianized. It's the one and only day of the year where it's safe to #bike on Woodward Avenue, our main street. I couldn't make it over there this year, but this photo shows Thanksgiving Eve a few years ago. #BikeTooter #BanCars
