E02: Ny-Ålesund column thermodynamic structure, clouds, aerosols, trace gases and radiative effects

PIs: Sandro Dahlke, Kerstin Ebell, Justus Notholt (former PI: Marion Maturilli)

The overarching goal of this project is to investigate the thermodynamic structure, clouds, aerosols, trace gases, and radiative effects in the atmospheric column over Ny-Ålesund (NYA), Svalbard, on a long–term basis. As found in phases I and II, NYA is located in the gateway to the Arctic, which is affected by the large-scale synoptic  setting, such as northwards intrusions of warm and moist air as well as southward excursions of cold, central Arctic air, each driving distinct cloud-, radiative-, and thermodynamic structure regimes. Through the progressing project, comprehensive observations of air mass characteristics, cloud parameters, aerosols, trace gases, and  their corresponding radiative effects have been gathered at the Arctic research station AWIPEV in NYA for a period of more than 8 years. The focus of phase III will be the  detailed process-based analysis of this data set by synthesizing the wealth of the different observations at NYA, which allow now to conduct robust interannual, inter-,  and intraseasonal analyses. The long-term observations at NYA and the enhanced observations from new instrumentation installed during phases I and II (e.g.,  cloud radar, infrared emission Fourier transform spectrometer (FTS)) will be jointly analyzed and also related to local, high-resolution modeling. A particular emphasis  will be given to the role of circulation weather types (CWTs) in driving the variability and changes in the observed parameters.

Hypothesis:

Signatures of Arctic amplification along with their dynamic and radiative effects can be revealed in the extensive observations of the Ny-Ålesund column.

In order to test the hypothesis, we will address the following central questions:

  • How do water vapor, clouds, aerosols, trace gases, precipitation, and associated radiative effects at NYA vary on intra- and inter-annual time scales?
  • How do circulation weather types, along with advection of airmasses from lower latitudes, modify these properties of the NYA column?
  • What is the impact of long-term changes and trends in circulation weather type characteristics on the past, recent and potential future development of the NYA  atmospheric state?

The vertically resolved measurements of the NYA column and its properties are a key tool for investigating processes that cause and contribute to Arctic amplification,  e.g., the impact of trace gases, aerosols, and clouds on radiation (SQ1). NYA is one of the very few Arctic stations with corresponding long-term meteorological upper-air  observations where signals of Arctic amplification can be observed (SQ3). At the same time, NYA is located in the Atlantic gateway to the Arctic and is influenced by  profound atmospheric exchange occurring between the Arctic and mid-latitude air masses (SQ2).

Achievements phase II

  • Continuous operation of remote sensing instruments (incl. cloud radar and new emission FTS) and retrieval products including new methods to characterize the  NYA column
  • Improved understanding of clouds, water vapor and associated radiative effects at NYA
  • Characterization of MCAOs and their footprint in the NYA column and sea ice concentration
  • Joint analysis of NYA data with high-resolution modeling, large-scale models and reanalyses
  • Evaluation of satellite products and creation of global maps for trace gases (satellite & NYA data)

Achievements phase I

E02 achieved an update of retrieval software for high resolution Fourier Transfrom Infrared (FTIR) spectrometer measurements (new and extended spectroscopy, trace gases and clouds in emission), in particular improving the retrieval of H2O and isotopes of water vapour. Improved retrievals of temperature, humidity, and Liquid Water Path (LWP) were also performed. Cloud macrophysical and microphysical retrievals for Ny–Ålesund data, based on new cloud radar observations at the AWIPEV atmospheric observatory, were analysed (Nomokonova et al., 2019b; Maturilli and Ebell, 2018). Furthermore, a detailed analysis of a one-year data set of vertically resolved cloud properties was performed, and the retrievals of aerosol microphysical properties were used to estimate the radiative impact of a biomass burning event (Ritter et al., 2018). Also, a first assessment of the cloud radiative efect at Ny-Ålesund in combination with a broadband radiative transfer model, and a quantification of atmospheric advective contribution to warming in the North Atlantic region of the Arctic were achieved (Dahlke and Maturilli, 2017).
