1. Data sets based on Argo: Role of Regional Centers 2009 ARC Meeting Sept. 29, 2009 Toulouse, FR

2. Discussion points What to call these things? – Data products? – Synthesis data sets? Is there a need to coordinate? Roles of science team and/or ARCs? – Validate/approve? – Design? Inventory efforts – Done regionally (by originator)?

3. Issues (cont’d) Do we have a clear idea of Argo users, how they access data, and in what form? – E.g., X-megabytes of Argo data are downloaded from the GDACs each month; of this Y% is done by operational modeling centers, Z% is done by individual researchers, etc. Similarly for synthesis products based on Argo – Here we would include an inventory of who is producing what and how often

4. What to conclude Revise our existing spreadsheet on Argo- related syntheses Come up with a specific recommendation for coordination of these syntheses, including roles of ST and ARCs if any If possible, identify needs for future development

8. Example data product: APDRC Taking raw data from GDAC and producing gridding products for use in models and other analyses Create horizontal maps of binned (profiles in a certain lat/lon box) and interpolated variables (temp, salt, density) and derived variables (MLD, BLT) Further make derived estimates of velocity
