Title Climate Science Modelling Language: Standards-based markup for metocean data
Contributors
Abstract Data interoperability requires agreements on metadata, data models, and service interfaces. Recent developments in standards for geographic information offer considerable potential for discovery and exchange of earth-related information. The ISO Technical Committee 211 is developing a raft of specifications for digital geographic information, metadata and services. In addition, the OpenGIS Consortium is developing a number of implementation specifications for web-enabled rendering and delivery of earth-related data. We present here a new data model and XML markup language for the climate sciences, based on emerging ISO standards. A number of climate-science 'feature types' are defined: for point, profile, and gridded data, as well as series of these in time and space. The model is applied, as part of the UK NERC DataGrid project, to a wide range of atmospheric and oceanographic data - both observed and simulated. The model is implemented using the current draft of ISO standard 19136 (Geography Markup Language), and drawing on a number of standard conceptual schemas. A mechanism is included for wrapping and aggregating file-based data storage (e.g. netCDF, GRIB, NASA Ames formats) to provide a uniform semantic interface to climate science data.
