2 Live Access Server (LAS) a configurable server

6 Desktop: Matlab, IDL, IDV, Ferret, GrADS, Information Products netcdf, HYCOM binary, ASCII, GIS layers

8 Compare fields

9 On-the-fly regridding from curvilinear to rectilinear coordinates

10 Similarly from hybrid-z to rectilinear

11 Simple analysis capabilities

12 HYCOM data at the desktop (for Matlab, IDL, Ferret, GrADS, ) The remote dataset is just a filename FDS is an OPeNDAP server standardizes datasets can perform analyses Vertical average of variable TEMP

13 FDS Delayed evaluation The whole domain appears to be transformed Calculations are on-demand, surgical Can greatly reduce network data volumes Can provide regridding on-the-fly

14 Ocean obs via LAS (incl. custom constraints )

16 OPeNDAP: network access to data and semantic metadata

17 Demanding (large) products may be created in batch mode

18 Scripted access to LAS Query available data sets: >lasls Query variables in data set model_1 : >lasls model_1 Query space-time domain: >lasls model_1 sst Request a subset of data as a file: ( asc for ASCII format) >lasget -x x 20:60 -y y 20:60 -t t 11-Dec Dec f asc model_1 sst

20 HYCOM is ready for integration with other data serving activities

24 for breakout: next steps Two categories of data management service: 1. Inward: for HYCOM Consortium members: provide forcing fields for "downscaling" intra-consortium collaboration & interaction tools access to validation data satellite fields, climatologies, other models, in-situ 2. Outward: for others the research community the "IOOS" (end user) community potential new HYCOM modelers

25 to think about: How to make "downscaling" simpler New products or services to add e.g. standard HYCOM viz New data to add validation friendly (regridded) fields Places we should advertise our data Potential users we should contact Systematic archive strategy e.g. High performance access to surface fields (Breakout discussions to follow )

26 Discussion? Questions?

27 Some areas to think about: How to make "downscaling" simpler New products or services to ad GIS layers HYCOM viz. New data to add validation friendly (regridded) fields Places we should advertise ourselves Potential users we should contact Systematic archive strategy -- especially easy access to HYCOM surface fields Reduced suite of variables (u,v,t,s,layer thickness) canonical vertical sections GUIs for Matlab & IDL Collaborative framework for assimilation investigations (mini-godae) Web site, including model descriptions Ability to compare results How to create a controlled environment for assimilation data Other metadata to add for on-line access (model configurations) Data retention periods for forecasts?
