OpenCDMS is a Reference Open Source Data Management System for atmospheric, hydrological, marine, phenological, composition and other environmental data with a time-series component. It stores observational data concerning water, weather, hydrology and climate in a secure and flexible manner and enables extracting useful information from the data.
OpenCDMS is intended to be used by the National Meteorological and Hydrological Services (NMHS) of WMO Members, and by any others wishing to use best-practices in managing and using these data.
At it’s most basic, a traditional CDMS allow users to enter observation data into a database.
Existing solutions may have many other capabilities, including:
Currently there is a very fragmented approach to CDMS development globally.
Many solutions have been developed using short-term intermittent funding and often the CDMS software is only developed and maintained by one or two people.
A WMO compliant CDMS meets all of the required sections of the CDMS Specifications.
The OpenCDMS Initiative is working towards being able to offer compliance testing and certification in the future.
