Summary
A brief description of the data.

A flying campaign to validate a new instrument to measure nitric acid and ammonia. Led by Dr. C. Percival, Manchester.

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.

CIMS was a flying campaign, Led by Dr. C. Percival, Manchester, to validate a new instrument to measure nitric acid and ammonia. CIMS aims at the installation, testing and demonstration of a Chemical Ionisation Mass Spectrometer on the UK FAAM BAe 146 aircraft that can measure nitric acid and ammonia with sufficient sensitivity to address many atmospherically important questions coupling the oxidation of oxides of nitrogen with the loss to aerosols. These problems dictate regional deposition and transport pathways and are of important regional air quality and climatic importance.

Data availability and file format

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

Access Restrictions

Access to and use of the data are ruled by the CIMS Data Protocol.
