Update: Intensive Observing Periods 2021/2022

10 March 2021

Following discussion with stakeholders and university hosts, the SPF Clean Air programme can confirm the timings of Intensive Observing Periods (IOPs) in 2021 and 2022.

The Winter IOP has been rescheduled for 2022. Precise timings will be provided in due course.

Winter IOP: January - February 2022

In addition, acknowledging the uncertainty caused by Covid-19, the programme can confirm that it remains the intention to proceed with the Summer IOP as previously planned and on the dates previously communicated.

Summer IOP: Monday 8 June to Friday 17 July 2021

For more information about the IOPs, including requests to participate, please send enquiries to james.allan@ncas.ac.uk.

More information

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.

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).
