Introduction
The FAAM
(Facility for Airborne Atmospheric Measurements)
puts at the scientists' disposal a large atmospheric research aircraft (the
BAE-146-301
aircraft) through a scheme of project selection and combined funding.
It is run jointly by NERC and by the UK
Met Office,
and is one of the NERC Centres for Atmospheric Science
(NCAS).
The BADC is the FAAM designated data centre.
The FLUXEX (Flux Experiment) project was an experiment to establish the fluxes of many ozone depleting gases (CFCs, HCFCs, halons) and greenhouse gases (HFCs, PFCs, SF6) from the UK. Its aim was to assess regional emission inventories of these gases to feed the UNEP/WMO Ozone Assessment and the UNFCCC. Attempts were also made to measure for the first time "new" ozone depleting gases, such as n-propyl bromide and hexachlorobutadiene, and to estimate UK emissions.
To achieve this purpose, the FAAM aircraft, fitted with air sampling bottles, was flown in the boundary layer upwind and downwind of the UK. A total of 9 flights took place between 30. March and 29. September 2005.
Data availability and file format
Data collected onboard the FAAM Bae-146 aircraft is stored in the
FLUXEX archive at the BADC.
These data include both core and non-core data (for a definition of core data, see the document on
FAAM Instruments).
FAAM processed core data are stored in
NetCDF.
Processed non-core data are stored in
NetCDF or NASA Ames. Raw core data are stored in zipped VMS files.
Some software to read, manipulate and convert these formats into each other are
provided by the BADC (software directory in the FAAM archive) or other agencies.
FLUXEX data are stored in either NetCDF or NASA Ames format.
File names follow the
BADC file name convention
and (for FAAM data) the
FAAM file name convention.
Access Restrictions
Access to and use of the data are ruled by the
FLUXEX Data Protocol.
- Access to the FAAM Bae-146 non-core data is now public, in agreement with the FLUXEX data Protocol. All users are requested to acknowledge the data providers in any publication based on FLUXEX data.
- Authorised users of the Processed Bae-146 core data now include everyone. If you would like to access these data , please follow the access to FAAM Processed core data instructions online. Access is granted automatically once you have agreed online with the FAAM Conditions of Use.
- Access to raw Bae-146 core data is restricted to the FAAM staff. If you are a FAAM instrument operator and would like to access these data, please follow the access to raw FAAM core data instructions online.
Note that FLUXEX data users are still requested to contact the principal investigators prior to any use of the data. FAAM scientists may request acknowledgement (or joint authorship) in any publications based, using or quoting their data.
For more details on FAAM data restrictions, please see the FAAM Data Access Rules.
