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们的合作努力，他们的研究重点是研究美国西部野火羽流的排放。 将采用一种取样策略，在NSF/NCAR C-130飞机上使用广泛的仪器来研究野火羽流中发生的大气化学反应。这一实地活动是与其他机构支持的相关活动合作开展的：诺阿的FIREX活动和美国航天局的FIREChem使命。这些活动计划于2018年夏末举行。云化学、气溶胶吸收和氮的西部野火实验（WE-CAN）活动解决了与固定氮、吸收气溶胶以及野火羽流中的云活化和化学有关的科学问题。这项研究的重点是最初排放后的第一天羽流演变。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散射和吸收。
