CLARIFY: in-situ airborne observations by the FAAM BAE-146 aircraft

Airborne atmospheric measurements were conducted aboard the UK FAAM (Facility for Airborne Atmospheric Measurements) BAE-146 aircraft as part of the CLARIFY project (Cloud-Aerosol-Radiation Interactions and Forcing; August–September 2017).

Centre for Environmental Data Analysis, date of citation. http://catalogue.ceda.ac.uk/uuid/38ab7089781a4560b067dd6c20af3769 This dataset consists of several measurement outputs, categorized as follows: "core_faam_CLARIFY.zip": includes outputs from the core instrument suite for each scientific flight. These instruments measure key atmospheric dynamics and thermodynamic variables, including wind speed and direction, temperature (T), and humidity. Gas measurements, such as carbon monoxide, are also included in core_faam. "core-cloud-phy_faam_CLARIFY.zip": includes outputs from a wing-mounted Passive Cavity Aerosol Spectrometer Probe (PCASP) and a Cloud Droplet Probe (CDP) for each scientific flight. "ccnrack_faam_CLARIFY.zip": includes outputs from a Droplet Measurement Technologies (DMT) dual-column cloud condensation nuclei (CCN) counter for each scientific flight, which measures the CCN concentrations at different supersaturations. "AMS_man_CLARIFY.zip": includes outputs from a compact time-of-flight aerosol mass spectrometer (C-ToF-AMS, Aerodyne Research Inc.) for each scientific flight, which measures mass concentrations of organic, sulfate, nitrate, and ammonium. "SP2_man_CLARIFY.zip": includes outputs from the Single Particle Soot Photometer (SP2) for each scientific flight, which measures black carbon (soot) content in individual airborne aerosol particles.
