What are the Objectives?
  • Produce budgets for comparison and evaluation
  • Produce budgets that take advantage of multiple FWI research projects
  • Identify gaps
What is the Spatial Domain?
  • Arctic Ocean or Pan-Arctic
  • Problem areas:
      - Arctic / North Atlantic Boundary, Greenland-Europe
      - Hudson's Bay
      - North Pacific (Yukon/Anadyr watersheds)
  • Hierarchy of domains
      - Sea Basins (ArcticRIMS)
      - Major watersheds + remaining drainage basins
      - Any other sub-domains for various problems and applications
Need input from the oceanographers - where to put the boundaries?
Domains need to be posted on the Arctic-CHAMP web site - who?

Temporal
What is the longest time period?
 Answer will depend on the length of the longest common records.

A.Assemble the relevant data sets for inspection?
B.Careful with gain/loss of important individual stations over time.
C.Graphics that display the # of river, rawinsonde, surface, etc. stations over time.
  Problem: Limiting on the basis of common intervals of data for different budget terms may eliminate a large fraction of existing data
D.Climatology first, individual years later.

What is the minimum time interval for resolution?
1 month

Encourage Data Redundancy
 Welcome all of these into grand data archive
 - compare them, explore their implications

e.g. several groups producing ET fields

**All contributors need to provide appropriate documentation of the uncertainties, errors.

We have defined a framework for:
  • presenting data
  • presenting model outputs
  • making comparisons between models and data
  • ArcticRIMS demo
Goal for next year:
  • ERA-40 data
  • UNH river discharge
  • UW ice/ocean/assimilation data
all up and into this framework by next year.
