Pumphrey, H, Schwartz, M, Santee, M L, Kablick, G, Fromm, M & Livesey, N J 2021, ' Microwave Limb Sounder (MLS) observations of biomass burning products in the stratosphere from Canadian forest fires in August 2017 ', Atmospheric Chemistry and Physics Discussions . https://doi.org/10.5194/acp-21-16645-2021
Forest fires in British Columbia in August 2017 caused a pyrocumulonimbus event that injected a polluted air mass into the lower stratosphere. The Microwave Limb Sounder (MLS) on the Aura satellite first observed the polluted air mass on 14 August 20

The Sub-Millimetre Radiometer (SMR) on board the Odin satellite performs limb sounding measurements of the middle atmosphere to detect molecular emission from different species. Carbon monoxide (CO) is an important tracer of atmospheric dynamics at t

In 1985, Scrimger [Nature 318, 647 (1985)] reported measurements of noise levels significantly above the ambient level for snow falling on a quiet freshwater lake. He examined only the time-averaged sound levels and did not report measurements of ind

Meteorological and atmospheric models are being extended up to 80 km altitude but there are very few observing techniques that can measure stratospheric–mesospheric winds at altitudes between 20 and 80 km to verify model datasets. Here we demonstra

It is known from ground-based measurements made during the 1982-83 and 1997-98 El Niño events that atmosphericHCN tends to be higher than usual during such years. The Microwave Limb Sounder (MLS) on Aura has been measuring HCNmixing ratios since lau
