ACCLIP: NOAA Single-Particle Soot Photometer (SP2) Data


Black carbon concentration data from the NOAA Single-Particle Soot Photometer (SP2) that flew aboard the NSF/NCAR HIAPER GV aircraft for 14 research flights during the ACCLIP campaign. Most flights were over the western Pacific Ocean. The final two flights were the transit flights from Osan, South Korea to Anchorage, Alaska and Anchorage to Broomfield, Colorado.

Archive note

Data is not available for RF01 (transit from Guam to Osan AFB) because of near total loss of data due to cloud interference.
