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 goal of the
ICEPIC
(Ice and Precipitation Initiation in Cumulus) research project
is to understand and quantify the formation and growth of ice particles
in cumulus congestus clouds by combining airborne measurements in cumulus
congestus clouds with Doppler radar measurements.
The FAAM aircraft, equipped with
leading edge cloud microphysics instruments, will be flown through
cumulus clouds in the vicinity of the dual-polarisation
Doppler radar
at Chilbolton.
The campaign is scheduled for the Spring of 2005.
Data availability and file format
Data collected onboard the FAAM Bae-146 aircraft is stored in the
ICEPIC 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.
ICEPIC 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
ICEPIC Data Protocol.
- Access to the FAAM Bae-146 non-core data is now public, after having been restricted to the ICEPIC participants during a period of time of 12 months following the end of the data set collection, in agreement with the ICEPIC data Protocol. All users are requested to acknowledge the data providers in any publication based on ICEPIC 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 ICEPIC 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.
