Data sets based on Argo:Role of Regional Centers

2009 ARC MeetingSept. 29, 2009 Toulouse, FR

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)?

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

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

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
