Welcome to the WDB wiki.
WDB (Weather and Water Database) 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. The system is the backbone of yr.no; Scandinavia's largest weather site. WDB has been in limited usage as a forecast archive since version 0.6.0 released in March 2008, and entered production usage on yr.no with version 0.7.8 at the end of February 2009.
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 (WDB2TS).
- 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/C++ and Java; it should be usable from any platform that can access a database.
- Open Source; licensed under GPL2 or (at your option) any later version.
You can access the full source code of the WDB system on github or browse the repositories on this site.
