Mercator Fellowships

Dr. Matthew Shupe (University of Colorado Boulder, USA)

Matthew Shupe has closely been engaged since the beginning of (AC)³. At first he served as a member of the Scientific Advisory Board (SAB) of (AC)³, later he was elected as an Associated Member (AM) and a member of the doctoral committee of Rosa Gierens (E03). As part of the proposed Mercator Fellowship, Matthew Shupe will investigate interactions of Arctic air masses with the variable Arctic surface, and their role in Arctic amplification. As a Co-Lead of the Coordination Team of MOSAiC, Matthew Shupe will strengthen the links between (AC)³ and MOSAiC. He will also be part of the HALO-(AC)³ campaign. Specific science topics including collaborations within (AC)³ of his fellowship are:

  • Cloud vertical structure including thermodynamics, microphysics, turbulence, and radiation (A01, A03, B03, E02, E03)
  • Cloud water budgets and persistence, including links to phase partitioning and mass flux (B03, E03)
  • Spatial transformation of cloud–ABL system relative to ice edge, including advective roles of moisture and aerosol (B03, B06)
  • Impact of cloud-atmosphere state on surface energy budget and radiation (A02, A03, C01, D03)
  • Representation of cloud and cloud-surface interactions in high resolution models (A01, E03)

Dr. Irina Gorodedskaya (Universidade de Aveiro, Portugal)

The major science objective of Irina Gorodetskaya in the framework of the Mercator Fellowship is to study the role of atmospheric rivers in the Arctic surface energy budget. Furthermore, she will investigate atmospheric and hydrological components (moisture, clouds, precipitation) in the context of the present and future Arctic amplification. Irina Gorodetskaya intends to participate
in the HALO–(AC)³ aircraft campaign. Specific science themes for this fellowship with direct links to (AC)³ projects include:

  • Mechanisms of the poleward moisture transport: extratropical cyclones, warm/moist air intrusions and atmospheric rivers (D01, B05, D03, E01, E02, E04)
  • Lagrangian study of the atmospheric rivers linking subtropical moisture sources and Arctic precipitation (D01, E01, E03, E04)
  • Cloud and precipitation microphysical processes associated with the atmospheric rivers, including the role of the long-distance transport of aerosol compared to the local sources (D02, E04, E01, E03)
  • Representation of anomalous moisture transport events and associated precipitation in high–resolution models (D02, E01, E02, E04, B05)
  • Changes in the sea ice (concentration, thickness, albedo) related to the atmospheric river events and warm/moist air intrusions and associated feedbacks (e.g., enhanced local evaporation) (D03, E04)
