The North Atlantic Climate System Integrated Study (ACSIS) - 1 year extension
Lead Research Organisation:
Plymouth Marine Laboratory
Department Name: Plymouth Marine Lab
Abstract
Major changes are occurring across the North Atlantic climate system: in oceanic and atmospheric temperatures and circulation, in sea ice thickness and extent, and in key atmospheric constituents such as ozone, methane and particles known as aerosols. Many observed changes are unprecedented in instrumental records. Changes in the North Atlantic directly affect the UK's climate, weather and air quality, with major economic impacts on agriculture, fisheries, water, energy, transport and health. The North Atlantic also has global importance, since changes here drive changes in climate, hazardous weather and air quality further afield, such as in North America, Africa, and Asia.
The ACSIS extension is a 1 year continuation of an ongoing 5-year strategic research programme called ACSIS: the North Atlantic Climate System Integrated Study.
ACSIS brings together and exploits a wide range of capabilities and expertise in the UK environmental science community. Its goal is to enhance the UK's capability to detect, attribute (i.e. explain the causes of) and predict changes in the North Atlantic Climate System. ACSIS is delivering new understanding of the North Atlantic climate system by integrating new and old observations of atmospheric physics and chemistry, of the ocean state and of Arctic ice, complemented by detailed data analysis and state-of-the-art computer simulations. Observations are obtained from diverse sources including NERC's observational sites in the North Atlantic, satellite remote sensing and the NCAS FAAM aeroplane. The computer modelling component is providing simulations of the atmosphere, ocean, and sea ice with unprecedented spatial detail.
The ACSIS extension will exploit advances made during the past 5 years to address specific new research questions which have arisen recently. It will investigate exciting evidence that changes in the climate of the North Atlantic/European region are much more predictable than was previously thought and will start to assess the impact of North Atlantic changes on the UK environment.

Title | Ozone eddy covariance measurements at Penlee Point Atmospheric Observatory, April-May 2018 |
Description | This dataset contains wind, temperature, pressure, humidity and ozone mixing ratio, given as the 20-minute mean of 10 Hz (ozone and wind) or 0.25 Hz (pressure, humidity and temperature) raw data. Ozone flux values calculated from the raw 10 Hz wind and ozone data are presented as mass fluxes and as molar fluxes. Deposition velocity is calculated from the molar flux. Data relevant to the data selection are also included, such as ozone variability, instrument sensitivity, wind stationarity and wind speed and direction. The Penlee Point Atmospheric Observatory (PPAO) site is best suited to observing fluxes over water. The north-west sector contains the sloping headland on which the observatory is built, making flux observations in this sector of limited value. The footprint area (where the measured flux is occurring) varies with wind conditions, but generally 90% of flux contribution occurs within 2-3 km of the observatory. The building itself sits 30-60m from the coast, depending on tide. Measurements were taken from 2018/04/10 - 2018/05/21 using a Gill WindMaster Pro sonic anemometer, a Gill MetPak Pro, and a high frequency chemiluminescence ozone detector from Eco Physics. A 2B 205 ozone monitor was used as a reference for the high frequency ozone instrument. Data collection was managed by David Loades (University of York), Thomas Bell (Plymouth Marine Laboratory) and Mingxi Yang (Plymouth Marine Laboratory). Data are missing where fluxes couldn't be calculated, most commonly due to heavy rain disrupting the anemometer or power outages. These data were collected for the Natural Environment Research Council (NERC) project Iodide in the ocean:distribution and impact on iodine flux and ozone loss. |
