NOAA atmospheric measurements are helping to support a national inventory of emissions from an important family of greenhouse gases.
New analyses of global air measurements show that five years after an unexpected spike in emissions of the banned ozone-depleting chemical chlorofluorocarbon CFC-11, they dropped sharply between 2018 and 2019.
World View Enterprises has offered to carry a miniaturized NOAA instrument on its high-altitude balloon to capture measurements of atmospheric particles on a series of flights in 2021 that will last weeks and cover thousands of miles at altitudes above 55,000 feet.
A sooty cloud generated by a 2017 firestorm provided an ideal opportunity for researchers to test a climate model that simulated the lifetime of that soot in the stratosphere.
A new NOAA and University of Michigan study using an instrumented airplane has found unexpectedly large emissions over five major cities along the East Coast - twice the total amount of methane and almost 10 times the amount estimated from natural gas.
