Summary
A brief description of the data.

FAAM Campaign in late 2005, beginning of 2006, which aimed at testing and improving the representation of mixed phase clouds in radiative transfer models.

Content
The actual data being described by this document. NB, in the case of data granules, this content may just be a reference to an ingested CSML or CDML file.

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 MICROwave investigation of MIXed phase cloud (MICROMIX) aims to test and improve the representation of mixed phase clouds in radiative transfer models. The intention is to fly the FAAM BAE-146 aircraft in conjunction with the Chilbolton radar facility and ASMU overpasses in order to characterise the in-situ microphysics, spatial variability of the microphysics and the radiative properties respectively. It is hoped that this activity will also act as a means of validating the microphysics retrievals that have been developed using the suite of remote sensing instrumentation at Chilbolton.

Data availability and file format

Data collected onboard the FAAM Bae-146 aircraft is stored in the MICROMIX 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.

MICROMIX 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 MICROMIX Data Protocol.

Access to the FAAM Bae-146 non-core data is now public, after having being restricted to MICROMIX participants during a period of time of 24 months following the end of the data set collection, in agreement with the MICROMIX data Protocol. All users are requested to acknowledge the data providers in any publication based on MICROMIX 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 MICROMIX 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.
