Link Description
Powerpoint Presentation by Jim Haywood summarising the requirements for measuring the interactions of light with aerosols and clouds, both direct and semi-direct effects. Jim explained the need to characterise the interaction of biomass burning aerosol overlying both cloud or ocean (in the absence of cloud). The presentations also describes general flight profiles and instrumentation for performing these radiation measurements.
Powerpoint Presentation by Simon Osborne regarding the deployment of ground-based instrumentation for the CLARIFY campaign to St Helena.
PDF FAAM instrumentation configuration for CLARIFY 2017, including general equipment, meteorological instruments, and instruments for radiation, chemistry, cloud physics and aerosol measurements. The document describes the locations of these instruments on the aircraft.
PDF A concise list of instrumentation to be deployed for CLARIFY.
Powerpoint Steve Abel describes options for the transit of the BAe-146 aircraft to the operating base (Walvis Bay) in Namibia. Steve also lists the roles of people on board the aircraft for the duration of the transits.
Powerpoint Steve Abel describes ongoing work on general flight plans for characterising cloud and aerosol-cloud interactions.
Excel Dates and allocation of hotel rooms to people on attachment to Namibia for CLARIFY.
Powerpoint Doug Anderson (FAAM) gives an overview of the hotels and their locations with respect to the airport where the BAe-146 will be based. Doug also describes the timetable for a typical working day.
