NOAA’s GOES-16 satellite captured methane released from two pipeline valves during a planned blowdown event. The methane plumes are estimated to be confined to the lowest 300 to 600 meters in the atmosphere with a width of 2 to 8 kilometers, as estimated by ground-based Lidar observations.

Air samples from NOAA's Mauna Loa Atmospheric Baseline Observatory provided the first evidence of new production of the ozone-destroying chemical CFC-11, in violation of the Montreal Protocol. A new study in Nature pinpoints the source of these emissions to two provinces in China.
