ExPLORE Complex Oceanographic Data WHAT THE OCEAN IS TELLING US ABOUT CLIMATE CHANGE | APRIL 23, 2013 ExPLORE Complex Oceanographic Data » ExPLORE = Extending Possibilities by Leveraging OPeNDAP for Remotely Exchanging » Ocean Data Interoperability Concept OPeNDAP (Open source Project for a Network Data Access Protocol) Data Format: NetCDF (Network Common Data Form) Metadata Convention: CF (Climate & Forecast) Existing tools: Matlab, python, R, custom interfaces,… Community Adoption: growing particularly in US, Europe and Australia » Web Services Inherent to OPeNDAP: Dataset descriptor structure (DDS), Query range and step size for a given parameter in time and space Extensions: Raw or quality controlled data access option, Metadata/dataset exploration OPeNDAP designed by oceanographers and computer scientists intially, web services have peeking functionaly, an interface that gives a more user friendly way to generate constraints for the URL, etc. Dataset Descriptor Structure (DDS), Data Attribute Structure (DAS), Information (INFO), HTML Data Request Form NetCDF has embedded metadata, and is a good framework for gridded data
