The observed rapid climate warming in the Arctic requires improvements in the monitoring of energy and matter exchange; accomplished by setting up appropriate (adapted to polar conditions) observation sites to measure turbulent fluxes. To address these problems, it is essential to improve the databases with high-quality in-situ measurements of turbulent fluxes near the surface applying the EddyCovariance method. These direct measurement data (CSAT3 sonic anemometer, KH20 krypton hygrometer, and laser scintillometer) obtained during the first Arctic Turbulence Experiment (ARCTEX-2006) in May 2006 at the French-German Arctic Research Base in Ny-Ålesund (AWI/IPEV) on Spitsbergen (Svalbard) allowed a comparison with simulated results from simple flux gradientparameterizations used today to force atmosphere-ocean-ice models. In addition, the results of this pilot study shows the problem of direct measurements (e.g. snow drift through the sensor path ways) under rough weather conditions as well as they reveal that the misestimating of sensible heat fluxes can result from inaccurate measurements or calculation of the surface temperature and inappropriate treatment of the neutral and stable conditions (e.g. intermittency, gravity waves) in the bulk parameterization. The primary goals of the ARCTEX-campaign were: 1. continuous measurements of high-resolution (20 Hz) turbulent heat fluxes near the tundra surface using a ultra sonic anemometer (eddy-covariance method) and an ultraviolet krypton hygrometer, 2. continuous measurements of the turbulent sensible heat flux near the tundra surface using the Laser-scintillometry, 3. measurements of standard meteorological data sampled at 1s intervals using a meteorological gradient tower (6 m and 10 m), 4. preand postprocessing of high-quality data sets of turbulent fluxes using state of the art flux data quality assessment techniques, 5. understanding of exchange processes and their parameterization for neutral and stable conditions, 6. validation of commonly used sensible and latent heat flux parameterizations (aerodynamic approach, bulk and gradient method). 4 2 General Information 2.1 Location Detailed geographic locations of the “Arctic Turbulence Experiment 2006” (ARCTEX-2006) at NyÅlesund (Svalbard, Kongsfjorden), May 2006, Universities of Bayreuth and Trier, Germany: General location Svalbard, Kongsfjorden, NyÅlesund, Position (Center of settlement): 078° 55’ 24’’ N, 011° 55’ 15’’ E Eddy-Flux complex UBT (EF): Coordinates: 078° 55’ 02’’ N, 011° 55’ 52’’ E Altitude: 13 m a. s. l.

The map (Figure 3.2) of Ny-Ålesund (Svalbard) shows the measurement sites during the ARCTEX-2006 campaign. The permanent AWI/IPEV sites used for this study are the 10 m meteorological tower of the Alfred Wegener Institute for Polar and Marine Research (MT1), the international standardized radiation measurements of the Baseline Surface Radiation Network (BSRN), the WMO 1004 radiosonde launch site (RS) and the temporary AWI tethered balloon launch sites TB1 and TB2. The temporary sites - build up by the Universities of Bayreuth and Trier - are the 6 m meteorological tower (MT2), the eddy-flux measurement complex with sonic anemometer (EF), and the Laser-scintillometer pathway (SLS). 7 TB2 RS TB1 MT1 MT2 EF SLS BSRN Eddy-Flux Complex UBT Meteorological Gradient Tower UBT Scintillometer UBT Figure 3.2: Map of Ny-Ålesund (Svalbard, Kongsfjorden) showing the measurement sites during the ARCTEX-2006 campaign: MT1 (10 m meteorological tower of the Alfred Wegener Institute for Polar and Marine Research), MT2 (6 m meteorological tower of the University of Bayreuth), EF (eddy-flux measurement complex), SLS (site for scintillometer measurements), BSRN (radiation measurements of the Baseline Surface Radiation Network), RS (radiosonde launch site), TB1 and TB2 (tethered balloon launch sites).

The measurements of this site are part of the routine meteorological observation program (surface radiation and mast measurements) operating since 1994 and headed by the AWI (http://www.awi-potsdam.de/MET/NyAlesund/wettertab.html).

Figure 3.4 shows the installed instrumentation of a micrometeorological gradient tower provided by the Univ. of Bayreuth (MT2) as used during the ARCTEX 2006 campaign. The tower was used to measure the near surface vertical gradients of air temperature and wind speed and additionally all components of the radiation balance.

Due to a malfunction of the CR23X data logging system (Campbell Scientific), caused by electrostatic discharge during shipping, we were not able to run the KH20 hygrometer. 16 -Program Security0000 0000 0000 -Mode 4- -Final Storage Area 20 -CR10X ID0 -CR10X Power Up3 -CR10X Compile Setting3 -CR10X RS-232 Setting- -1 5.2 Laser Scintillometer (SLS) The SLS20 Scintillometer was operated using the Scintec DOS-based software SLSRUN.exe version 2.10 (Figure 5.2). Path length and height were set as described before; average air temperature and pressure were adjusted for every measurement period (usually one day). Before any measurement period an automatic Background Alignment test was executed to eliminate signal noise and to handle the channel crosstalk. To recalculate the turbulent fluxes the required representative temperature values were calculated as the mean of the measurement heights of 0.7 m and 2.4 m a. g. l. The representative air pressure at station height was taken from the AWI meteorological routine measurement observation.

The used Vaisala QSP-configuration files were: ArctexQ1.qsp (temperature, radiation, wind) and ArctexQ2.qsp (temperature and wind). The used sensors for ARCTEX-2006 campaign were: 5 x cup anemometers, 3 x ventilated thermometers, 1 x net radiation CNR1 and 1 x infrared thermometer KT15IR; optional: 4 x soil temperature and 2 x soil heat flux (not used 2006).

Height of CSAT above ground: 2.23 to 2.25 cm Orientation against North: 128° to 130 ° (SE) Height a.s.l.: app. 18 m Surface conditions: wet, melting snow over ice, some snow free spots (black soil, tundra). First try to communicate with CR23X. No communication with CR23X possible! Intensive error search without success! May, 4, 2006 Thursday Ny-Ålesund Further error check to solve communication problem with CR23X! Successful parallel installation Gradient tower: Heights of installed instruments: 1. Height: 073 cm above ground (snow) (Cup anemometer + Psychrometer) 2. Height: 142 cm a. g. (Cup anemometer) 3. Height: 237 cm a. g. (Cup anemometer + Psychrometer) 4. Height: 385 cm a. g. (Cup anemometer) 5. Height: 563 cm a. g. (Cup anemometer + Psychrometer) Start of measurements gradient tower at May 4, 21:10 CET (Start of Cup anemometer at height of 563 cm at May 05, 19:20 CET!) 32 Bisher erschienene Arbeiten der Reihe “Arbeitsergebnisse Universität Bayreuth, Abteilung Mikrometeorologie”: Nr Author(s) Title Year 01 Foken Der Bayreuther Turbulenzknecht 01/1999 02 Foken Methode zur Bestimmung der trockenen Deposition von Bor 02/1999 03 Liu Error analysis of the modified Bowen ratio method 02/1999 04 Foken et al.
