Air and aerosol sampling facilities
The RRS Sir David Attenborough will be equipped with air and aerosol sampling facilities, drawing air from two locations – at least 2m in front of the vessel’s bow and above the crow’s nest. These locations will further ensure undisturbed samples of clean, ambient air uncontaminated by ship emissions.
Large-diameter stainless steel tubing with minimal bends will be used for the aerosol sampling system, where conductivity and corrosion resistance are critical. The aerosol lab will be located at the very top deck to minimise the distance between the sampling location and the laboratory.
Scientific meteorological equipment will be mounted in the same locations to ensure redundancy, with connections to the relevant atmospheric science laboratory space. An HRPT receiver will facilitate communication with weather satellites providing the latest high-resolution picture transmissions.
RRS Sir David Attenborough will further be equipped with the following meteorological and atmospheric instrumentation:
- Full suite of meteorological sensors
- Freezing rain and detection of icing conditions
- Dew point chilled mirrored hygrometer
- Clean air sampling System
- Visibility sensor
- Solar/IR radiometer
- Sea surface temperature
- CO2/CH4/CO/H2O atmospheric science lab
