Clean Air: Analysis & Solutions - Advance notice of 2021 intensive observing periods

23 July 2019

The partners in the Clean Air programme would like to encourage community participation in a co-ordinated UK observing intensive period in 2021.

The aim of this early announcement is to facilitate a mobilisation of interested communities of researchers around two pre-defined periods. It is hoped that an early signposting of these dates will allow interested parties to seek funding, coordinate field and equipment deployments and align PhD projects.

Winter observation period: January to February 2022 (rescheduled, precise dates TBC)
Summer observation period: Monday 7 June to Friday 17 July 2021

The Clean Air programme is supporting detailed long-term urban air quality measurements at three NERC supersites located in central London, Manchester and Birmingham. Each supersite has agreed to provide practical and logistical support to additional multi-disciplinary researchers and experiments during the intensive observing periods, enabling for example:

  • deployment of specialised atmospheric chemistry equipment
  • short-term observations of boundary layer meteorology and structure
  • enhanced collection of particulate and gas samples for laboratory analysis
  • testing of new or proof-of-concept instrumentation
  • instrument calibration inter-comparisons and performance evaluation.

Other ground-based observing facilities in the UK are also likely to be available for research users during the mobilisation period, details to be updated on the forthcoming Clean Air website.

Wider scientific benefits are envisaged through a coordination of intensive observation periods with other research activities such as:

  • mobile surveys of the distribution of pollution by vehicle, drone or aircraft
  • personal exposure, activity surveys and health studies
  • high resolution modelling of pollution distributions
  • targeted emissions observations
  • health effects and biomarkers of exposure studies aligned to detailed atmospheric composition measurements
  • computational / technological approaches for better integration of environmental with health data
  • relevant indoor studies that would gain value from being coordinated with intensive outdoor observations and modelling.

Some limited financial resources may be available from the National Centre for Atmospheric Science (NCAS) to support third-party participation in the intensive observing periods at the NERC supersites (covering costs such as shipping, transport, travel and consumables, but not staff time). Further details will be provided by NCAS later this year.
