  1. Ocean/Atmosphere observations A. Proshutinsky, WHOI Arctic System Model workshop III Montreal, Canada, July 17th, 2009 10:50 – 11:10 • Model forcing validation • Data for oceanic model validation

  2. Model forcing validation: Air temperature, humidity, SLP, wind, SLP, cloudiness from NCAR/NCEP can be validated based on North Pole stations Data Coverage: 1954-1991 and 2003-2006 Temporal Spatial

  3. Sea Level data sources http://www.whoi.edu/science/PO/arcticsealevel/ Monthly mean relative sea levels were provided by the Arctic and Antarctic Research Institute for 71 stations (see station numbers) located in the Barents and Siberian Seas. The time series of sea level variability generally cover the period between 1948 and 2008 but temporal coverage differs significantly from station to station. Red denotes stations with the most complete datasets. The best data are available from 9 stations (blue circles) for the period 1954 – 2008.

  4. Ocean data: T,S, currents T&S for 1846-2006: 583138 oceanic stations (AARI data archive) Currents:2250 mooring sites with 9735 months data(thanks Greg Holloway for data collection)

  5. Reconstructed circulation/fields: a) Chukchi Sea, Panteleev et al., JRG, 2009, submitted Model-mooring error: 0.37 Model-mooring error: 0.3

  6. Circulation of the Kara Sea based on modeling with data assimilation, Panteleev et al., JGR, 2007.

  7. Fram Strait fluxes, AWI

  8. Bering Strait fluxes, T. Weingartner (UAF), R. Woodgate (UW)

  9. Fresh water and heat content
