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).  Associated datasets are also available at: Facility for Airborne Atmospheric Measurements; Natural Environment Research Council; Met Office (2017): CLARIFY: in-situ airborne observations by the FAAM BAE-146 aircraft.

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.
