Reference excerpt

Mace Head Atmospheric Research Station is located on the west coast of Ireland, and is one of the longest running mercury recording stations in the world. The station's location is important as it is far away from neighbouring cities, to ensure no pollutants interfere with recordings, and its location is suitable for studying the atmosphere under Northern Hemispheric and European conditions. The station has the dual status of being a World Meteorological Organization (WMO) Global Atmosphere Watch (GMO) station and a European Monitoring and Evaluation Program (EMEP) supersite. Mace Head research and monitor the climate and atmospheric composition, focusing on aerosol-cloud interactions and mercury readings.

About Mace Head Atmospheric Research Station was established in 1987, and is still in operation. The current station manager is Gerry Spain, who has held this position for the last 20 years. The station PI/Contact is Professor Simon O'Doherty, who runs trace gas measurement at the University of Bristol, and the station CO-PI is Professor Peter Simmonds. Mace Head funding is supported by the UK's Department for Energy Security and Net Zero and NASA. The station has the dual status of being a World Meteorological Organization (WMO) Global Atmosphere Watch (GMO) station and a European Monitoring and Evaluation Program (EMEP) supersite. It is operated by both the National University of Ireland Galway's School of Physics and the University's Ryan Institute Centre for Climate and Air Pollution studies. The University of Galway's School of Physics has operated at Mace Head for 50 years, and Mace Head Station is one of the more important Global Atmosphere Watch stations in the Northern Hemisphere. With funding from research projects, it is the University's personnel; the students and post-doctoral fellows who are responsible for the operation and maintenance of equipment at Mace Head station. The University provides funding for the costs of consumables such as filters, as well as the transport of chemical analysis samples to the Glasnevin, Dublin laboratory.

Location The Mace Head Atmospheric Research Station is located in Carna, County Galway, on the west coast of Ireland. This Northern Hemisphere station has westerly exposure to the North Atlantic Ocean, with coordinates of 53.3267ºN, 9.9046ºW. This is a clean sector from 180 degrees to 300 degrees, and approximately 60% of the air that is measured by the site arrives through this clean sector. Time in Ireland is Western European Time (WET, UTC+00) in winter and Western European Summer Time (WEST, UTC+01) in summer (although, at almost 10°W, local solar time is 40 minutes later than civil time). Annual rainfall is 1,200mm, 10 °C average air temperature, and a sea temperature of 10 °C in winter and 15 °C in summer. Peat lands and wetlands surround the station, and its location is approximately 90 metres (300 ft) from the shoreline. To reduce pollutants influencing and interfering with measurements taken at the site, Mace Head is located approximately 88 kilometres (55 mi) west of Galway city. Similarly, the clean sector surrounding the site also includes three small close surrounding islands, but they are uninhabited and thus do not influence the measurements taken at the site. Furthermore, the main Atlantic shipping routes are over 150 km (93 mi) away, and the transatlantic air corridors are over 80 km (50 mi) away, thus ensuring cleaner readings. The location of Mace Head makes it a suitable site for measuring marine biogenic gases, aerosol production and chemistry, and long-range transport of air pollution. It is also suitable for studying the atmosphere under Northern Hemispheric conditions as well as European conditions during eastern winds. There are numerous facilities on the site used for recording and analysing data. These facilities consist of a 10 m (33 ft) tall meteorological tower, an aluminium walk-up tower and a cargo container laboratory, and three laboratory buildings; one that is 300 m (980 ft) from the shore, and two that are 90 m (300 ft) from the shore.

History Research and operations began during 1978 to 1983 in Adrigole, County Cork. However, this was shut down and the operations officially moved to the Mace Head site in 1987. It was from 1987 that measurements of chloroform, methane and trichlorotrifluoroethane began, and in 1995 carbon monoxide and hydrogen began. In October 1994, the Advanced Global Atmospheric Gases Experiment (AGAGE) network installed their first automated gas chromatography-mass spectrometer. It was later replaced by the Agilent 5973 MS in 1998, and in December 2004 was retired and the Medusa gas chromatography-mass spectrometry system (Medusa-GCMS) was installed.

Mission statement and research themes The Mace Head station has numerous research aims and themes, such as monitoring climate change, atmospheric composition, aerosol-cloud interactions, air quality, atmosphere-ocean exchange and climate-ecosystem interactions. Their mission statement states that their goal is to monitor trends of atmospheric composition change, monitor climate variables and air pollution, and research atmospheric composition and its impact on climate change. Mace Head also wants to promote education within the topics of climate, air pollution, and the atmosphere.

Instruments Mace Head uses a variety of instruments to record their findings. Some of these instruments include a ceilometer and doppler lidar, both used to detect clouds and aerosols, a cloud radar, microwave radiometer and a nano-scanning mobility particle sizer. Mace Head also has a gas chromatography–mass spectrometry system (Medusa-GCMS), which was installed in December 2004 and measures trace gas species. Mace Head also has an automated atomic fluorescence analyzer (AFS) and an automated atomic absorption analyzer (AAS), both used to measure time resolved mercury measurements. There is also a cavity ring-down spectrometer (CRDS) which is used to measure carbon dioxide and methane. There is also a gas chromatorgraph-electron capture detector (GC-ECD) to measure sulphur hexafluoride and nitrous oxide, and a gas chromatophraph-multi detector (GC-MD) to measure carbon monoxide and hydrogen.

Worked examples

Example 1 — a first encounter with Mace Head Atmospheric Research Station

Start with the simplest possible case. Write down what Mace Head Atmospheric Research Station claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Mace Head Atmospheric Research Station before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Mace Head Atmospheric Research Station ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Mace Head Atmospheric Research Station

In research: Mace Head Atmospheric Research Station appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Mace Head Atmospheric Research Station in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Mace Head Atmospheric Research Station is common in secondary-school and first-year university syllabi. It links to neighbouring topics Buildings and structures in County Galway, Mercury (element), Regional Specialized Meteorological Centres, so understanding it makes those chapters shorter.
In everyday life: Look for Mace Head Atmospheric Research Station outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
