This is a collaborative effort between scientists from 5 western universities whose research is focused on the study of the emissions from western U.S. wildfire plumes. A sampling strategy will be employed using a wide range of instrumentation on the NSF/NCAR C-130 aircraft to study atmospheric chemical reactions occurring in wildfire plumes. This field campaign is being conducted in collaboration with related campaigns supported by other agencies: the FIREX campaign by NOAA and the FIREChem mission by NASA. These campaigns are planned to take place in the late summer of 2018. The Western wildfire Experiment for Cloud chemistry, Aerosol absorption and Nitrogen (WE-CAN) campaign addresses scientific questions related to fixed nitrogen, absorbing aerosols, and cloud activation and chemistry in wildfire plumes. This research focuses on the first day of plume evolution following initial emissions. The chemistry and microphysics occurring during this time impacts the partitioning of reactive nitrogen, alters cloud chemistry and nucleation, and largely determines aerosol scattering and absorption.

这是来自 5 所西方大学的科学家之间的合作成果，他们的研究重点是美国西部野火羽流的排放。 将采用 NSF/NCAR C-130 飞机上的各种仪器进行采样策略，以研究野火羽流中发生的大气化学反应。该实地活动是与其他机构支持的相关活动合作进行的：NOAA 的 FIREX 活动和 NASA 的 FIREChem 任务。这些活动计划于 2018 年夏末进行。西部野火云化学、气溶胶吸收和氮实验 (WE-CAN) 活动旨在解决与野火中的固定氮、吸收气溶胶以及云活化和化学相关的科学问题羽毛。这项研究重点关注初始排放后羽流演化的第一天。在此期间发生的化学和微物理影响活性氮的分配，改变云化学和成核，并在很大程度上决定气溶胶的散射和吸收。
