  • The European AQUA Thermodynamic Experiment (EAQUATE) was a study of the atmosphere, the land surface and the ocean surface by means of a range of airborne high resolution souders, in conjunction with observations from the Aqua and Aura satellites. The EAQUATE archive held at the British Atmospheric Data Centre (BADC) includes data collected aboard the Facility for Airborne Atmospheric Measurements (FAAM) Bae 146 aircraft based at Cranfield, UK, during four flights in September 2004.

  • The Contrail Forecast Verification Experiment (COVEX) was a Met Office experiment to validate the new contrail forecasting techniques based on engine parameters and environmental conditions. It was based on a one-flight experiment on board the Facility for Airborne Atmospheric Research (FAAM) aircraft, that took place in December 2004.

  • This project was a trial to test the operation of the NEON Infra-Red camera mounted on board the Facility for Airborne Atmospheric Measurements (FAAM) BAE-146 aircraft. The camera was used to detect the contrast between a runway and surrounding grass areas.

  • T-REX (Formerly SWRP - Sierra Wave Rotor Project) was a joint American/European project that took measurements of strong gravity wave activity and associated rotor activity beneath the waves in the lee of the Sierra Nevada mountains, California, USA. Measurements were made by three aircraft including the FAAM BAE-146 aircraft and many ground based instruments. The UK partners are the Met Office and the University of Leeds. Motivated by aviation safety issues, the main scientific objectives are to improve the understanding of the atmospheric conditions conducive to strong gravity wave activity, wave induced rotors and gravity wave breaking.

  • The LAND EMISSivity experiment (LAND EMISS) aimed to study the thermal infrared emissivity of a range of different land surface types using the Facility for Airborne Atmospheric Measurements (FAAM) BAE-146 aircraft. The UK based campaign made use of the FAAM BAE-146 aircraft during early summer 2006 with an additional period of UK-based flying in summer 2007, and opportunities for flights over snow and ice were investigated.

  • Measurements were made using the FAAM BAE-146 aircraft throughout the troposphere in the locality of the Tropospheric Organic Chemistry (TORCH) field campaign in Writtle, Essex to determine the influence of regional transport and local chemistry on ozone concentrations. The Production of Ozone of South-east England (POSE) project aimed to further the understanding of the factors governing ozone chemistry during summer periods in the UK. In particular, the relative sources of ozone: general Northern Hemisphere background, regionally produced products and local/in situ generation. The transport of pollutants from Europe within the boundary layer has been implicated in the very high levels of ozone seen in the UK during summer 2003. During the TORCH field campaign in Writtle, Essex, high levels of ozone and other reactive species were seen during the 2003 heatwave, and results suggest that this may be a result of mixing down of polluted air from aloft during the collapse of the night-time shallow inversion layer to form the day time boundary layer. In order to better understand this behaviour, the FAAM BAE-146 aircraft perfomed a series of profiles close to the Writtle site, to determine the influence of regional transport and local chemistry on ozone concentrations. Measurements included CO, ozone, hydrocarbons and oxygenated VOCs, throughout the troposphere.

  • Study of intercontinental transport of air pollutants by means of coordinated flights over the East coast of North America, the Azores and the West coast of Europe. ITOP was a component of the International Consortium for Atmospheric Research on Transport and Transformation (ICARTT), an international initiative which coordinates the efforts of various American and European groups who have developed plans for field campaigns in the summer of 2004, with the aim of improving our understanding of the factors determining air quality over the two continents and over remote regions of the North Atlantic. The British contribution to ITOP, referred to as ITOP-UK, was funded by the Natural Environment Research Council (NERC) through the Upper Troposphere Lower Stratosphere (UTLS)-Ozone Directed Research Programme. The ITOP-UK dataset includes trajectories and other forecast products calculated by John Methven (University of Reading), based on European Centre for Medium-Range Weather Forecasts (ECMWF) forecast wind fields, to support ICARTT flight planning, near-real-time chemical analyses produced by the University of Cambridge, and data collected aboard the FAAM Bae-146 aircraft in July and August 2004.

  • Atmospheric chemistry measurements were made during a series of campaign flights by the Facility for Airborne Atmospheric Measurements' (FAAM) BAE-146 research aircraft as part of the NERC funded RONOCO (ROle of Nighttime chemistry in controlling the Oxidising Capacity of the AtmOsphere) consortium project. These campaign data are available along with model output from the Met Office's Air Quality Unified Model (AQUM). The scientific objectives of RONOCO were to determine the morphology of tropospheric NO3 in different meteorological conditions and seasons, and in a range of gas phase and aerosol environments, in order to quantify the key processes and pathways of oxidized nitrogen chemistry at night in the troposphere. The ultimate aim was to assess the pervasiveness and importance of night time chemical processes, and in particular NO3, for UK regional and Western European air quality, eutrophication, and ultimately to quantify its linkages to climate change. The dataset contains images from the model output in png format.

  • The Infrared Atmospheric Sounding Interferometer (IASI) instrument was launched on the METOP satellite in October 2006 (delayed from April 2006). The European Organisation for the Exploitation of Meteorological Satellites (Eumetsat) is providing funds for the Facility for Airborne Atmospheric Measurement (FAAM) aircraft BAe146 to be involved in validation of IASI radiative transfer and some level 2 products. Flights were flown over oceans to coincide with METOP satellite overpasses. Further flights were flown low level over specific land calibration sites to characterise land surface emissivity. There were co-incident flights with other platforms including US ER-2 or Proteus aircraft and French high altitude balloon. This dataset contains FAAM flight tracks and flight summaries, it does not, however, contain data collected by IASI on the Metop satellite.

  • Ground based and airborne in-situ aerosol measurements during the APPRAISE-CLOUDS (Aerosol cloud interactions and climate) project from the Chilbolton Atmospheric Observatory, Hampshire (South West England) and on board the FAAM BAE-146 research aircraft. The data were collected for use in the CLOUDS project, which is one of multiple projects within the APPRAISE (Aerosol Properties, PRocesses And Influences on the Earth's climate) programme. Airborne measurements for the APPRAISE-CLOUDS project were also carried out using the FAAM BAe146 aircraft. In total 20 flights were carried out as part of this project with the aircraft operating from Cranfield, Exeter and Oberpffafenhofen, Germany. For the APPRAISE-CLOUDS project the aircraft was equipped with a range of cloud and aerosol instruments including FSSP (cloud droplets), CPI (ice particles), 2DS (ice particles), 2DC (ice particles), 2DP (ice particles), CAPS (droplets, ice, large aerosol), AMS (aerosol chemistry), SP2 (soot aerosol), PCASP (aerosol size), SMPS (aerosol size), Filters (aerosol chemistry), CVI (cloud particle residuals), Nephalometers (aerosol scattering), PSAP (soot aerosol), Whole Air Samplers (trace gases - post flight analysis), Trace gas analysers (NOx, O3, SO2). Missions typically involved flight legs above and below cloud to characterise aerosol in the vicinity of the clouds, and flight legs within cloud to characterise cloud properties and attempt to measure cloud particle residuals. In total 110 flight hours were allocated to this project.
