WDB - Weather and Water Database

Welcome to the WDB project's home page.

WDB is a database system designed to store meteorological, hydrological and oceanographic (MHO) data in a PostgreSQL database management server. The purpose of the WDB system is to improve the quality and effectiveness of IT systems for MHO production by providing a flexible and effective data storage solution for real-time and archive data. WDB is the backbone of yr.no; Scandinavia's largest weather site.

The WDB system consists of a database server system including a read/write interface to the database, a set of loading programs for inserting various types of MHO data into the system, and a http product generator.

  • Decode and store meteorological and oceanographic forecast fields
    • WDB has loading programs to load forecasts, analysis, wave and circulations models stored in GRIB1 and FELT format. Metadata is provided for HIRLAM fields
  • Flexible retrieval interface
    • The WDB Call Interface (WCI) allows the extraction of entire fields or points (time-series) from the database using an SQL-based function interface.
    • WCI is compatible with C++; it should be usable in C, Java, Perl, Python, and Fortran as well (however, these interfaces are not yet tested).
  • Open Source
    • WDB is licensed under GPL2 or (at your option) any later version.

The latest release of WDB is version 1.0.1. WDB has been in limited usage as a forecast archive since version 0.6.0 released in March 2008. WDB entered full production usage on yr.no with version 0.7.8 at the end of February 2009. Currently, the yr.no website is run on a backbone of WDB servers.

You can access the WDB source code on github.
