Available FAAM instruments have been sub-divided into groups in common with the FAAM instrument working group areas. These groups are listed in the Main Menu on the left.

FAAM CORE INSTRUMENTS

Core instruments are provided and operated by FAAM, for which data will be made available routinely at BADC. Some core instruments may not be operated on all flights. The standard core instrument data may, in some cases, be enhanced (e.g. provided at higher frequency or with greater accuracy) by collaboration with another group. Where use of core instruments incurs significant extra charges for consumables (e.g. dropsondes, SATCOM data transfer), these additional costs have to be recovered directly from the user. The list of "core" instruments will be periodically reviewed by the FAAM Operations Committee, instruments may be removed or added to the list depending on changes in user requirements or serviceability.

NON-CORE INSTRUMENTS

Use, calibration and data processing for non-core instruments must be arranged with the instrument provider. This might be as a purchased service or as a scientific collaboration.

Cloud Physics Instruments

 

Multiple cloud probes are owned by FAAM to cover a range of cloud-particle sizes from 3µm to 6500µm. The measurable particle/droplet sizes of the cloud probes are illustrated in the diagram below. This extensive range allows for the measurement within all cloud types at different stages of evolution. Also illustrated are the sizing capabilities of some aerosol instruments.

The probes are wing-mounted in canisters, shown to the left,and include both optical particle counters (OPC) and optical array probes (OAP). The core wing-mounted OPCs are PCASPand CDP; OAPs are the CIPs. The 2DC is also an OAP but was retired in December 2014
