1 Ny-Ålesund: Site Update & Atmosphere Flagship Program Marion Maturilli, Sandro Dahlke, Roland Neuber, Andrea Merlone GRUAN ICM-9, Helsinki, Finland,12-16 June 2017
2 Transition from RS92 to RS41 now 1 x daily RS92 1 x daily RS41 Ny-Ålesund 1 year 1 year 1 x weekly dual sounding 1 April 2017 Ny-Ålesund standard radiosonde changed to RS41 (RS41 currently no GRUAN data product)
3 Ny-Ålesund Dual Soundings RS92-RS41 recommendation last year Initiative for Technical Note on Multiple Soundings RS92-RS41 dual sounding, May [von Rohden et al., GRUAN-TN-7]
4 Ny-Ålesund CFH Soundings with RS41 more compact payload smaller balloon + external parachute data receiving with MW41 easier handling of hard- and software generally easier operation Future CFH launches in Ny-Ålesund will be operated by the regular station personnel (after technical introduction at AWI Potsdam).
5 Upcoming Activities Northern Hemisphere Special Observing Periods 2018 JUL AUG SEP NH-SOP s Ny-Ålesund 4 x daily radiosoundings
6 Currently Activities Campaign as part of ArctiC Amplification: Climate Relevant Atmospheric and SurfaCe Processes, and Feedback Mechanisms (AC) 3 funded by the German Science Foundation (DFG)
7 Arctic Amplification Meridional Transport (Atm/Ocean/Sea Ice) Near-Surface Air Temperature Rise Global CO Warming 2 More Downward Terrestrial Radiation Larger Eddy Fluxes More Water Vapour & Clouds Warmer Oceanic Mixing Layer More Aerosols, Soot (Atm/Sur) Lower Surface Reflection, More Solar Absorption Sea Ice Melts Increased Biological Activity in the Ocean Adapted from Wendisch et al. (2013)
8 Current Activities Campaign as part of ArctiC Amplification: Climate Relevant Atmospheric and SurfaCe Processes, and Feedback Mechanisms (AC) 3 PASCAL ship-borne campaign Polarstern ACLOUD air-borne campaign Polar-5 and Polar-6 Ny-Ålesund observatory - cloud radar - aerosol lidar - microwave radiometer - surface radiation and others 4 x daily radiosoundings 26 May 22 June 2017
9 Recent Activities Radiosonde Campaign December x daily radiosonde launches 5 22 Dec 2016 Aim: Recent Results data assimilation experiment in winter period Increased persistence of extreme cyclone events period was chosen because of winter storm probability in early winter [Rinke et al., submitted to Env. Res. Lett.] Increase in advection from lower latitudes [Dahlke and Maturilli, manuscript in preparation]
10 Arctic Winter Temperature Trend (December-January-February) Key Region of Arctic Climate hpa, from ERA-Interim significant trend (95% confidence level) The Ny-Ålesund Atmosphere Flagship
11 Ny-Ålesund International Research Community, 11 nations hundreds of research projects different research topics similar research topics
12 Ny-Ålesund Science Managers Committee (NySMAC) was established to enhance cooperation and coordination among researchers and research activities in Ny-Ålesund.
