1New Climate Databases Management Systems (CDMSs) EXPERT MEETING ON METEOROLOGICAL INFORMATION FOR LOCUST CONTROL18-20 October 2004, GenevaHama Kontongomde
2(The CLICOM Project ) Main Achievements Main deficiencies Provision of hardware and commercial software,Improvement of computerized literacy of the local staff in developing countries was improved..Improvement of expertise of computerized climate data processing (data entry, data quality control, data archiving and retrieval)Main deficienciesStill in DOSCannot use different Database Management Systems,Not a Client / Server System , Internet Connections etc.No link to Geographical Information Systems (GIS)
5MetadataElements in the metadataPossibility to add more elementsPossibility of supporting graphical elementsInformation on equipment and instruments
6Metadata Station name station number/identifier date or date range latitude/longitudeelevationcountryclimate element (temperature, etc)Maps, photos etc..other
7Import of Digital DataMessages that can be imported (TEMP, METAR, SYNOP, CLIMAT…)Importation of multiples data files for one stationImportation of multiples data files for multiple stationsImport data from CLICOM
8Validation and Quality Controls Quality control flagsAre QC results storedSystem offers replacement estimates for fail QCQC validationMethod of defining ranges values for comparisonSpatial coherence
9Data ExtractionTraining time for data extraction (1 hour, 1 day, more than a day..)GUI to enter data extraction parametersExamples for command line queries
10Type of variables Hourly data Daily data 10-day data Other (specify in Annex)Daily summary10-day, monthly, annual summariesExtreme values
11Output Products Tabulated data (hourly, daily, …) Tabular summary of statistical analysisTypical types of statistical analyses (means, std, frequency analyses..)Graphical products (time series, Upper air sounding, contour analyses..)Output formats supported (ASCII, HTML, PDF, XML, CSV…)WMO messages (CLIMAT, CLIMAT TEMP, ..)
12CLIDATA (Czech Republic) Build around the ORACLE RDBMS and associated management and data discovery toolsprofessionally designedscalable for use in all sizes of climate data organizationsprovides multi-language support and flexible specification of quality control procedures.
13CLISYS (France)CLISYS package is built using, primarily, open source software packagesMajor components: Linux operating system, Oracle RDBMS, ZOPE application server, and python scripting language capability.Plans are underway to test and evaluate use of the PostgreSQL RDBMS as an alternative to ORACLE an to develop a “light version” of Clisys.Stand-alone data entry module (ELIAD) that allows for off-line data entry without requiring a direct connection to the database.
14CLIWARE (Russian Federation) CliWare is the most technologically advanced of the systems reviewedIt uses a client-server model that can access data locally or over a network connection to a remote database through an http socketCommunicates with the database uses JDBC calls that allow for different database engines to be utilized for the underlying data store (Oracle, SAP DB, PostgreSQL RDBMS ...)

17Cliware : Data dissemination To disseminate data system uses TCP/IP public network Internet and provides two type of data access: Bach Client (Application) and User. Both types use HTTP protocol to data access. The data and products can be present in formats: MeteoXml, HTML, text tabulated data, graph images, Geo images, FM codes
18J C D M S (Jordan)System specifically, to manage data collected from the network of climate data stations in JordanData tables and attribute definitions are tailored Addition of different observation types and reporting intervals would require modification to the data system which is based on an ORACLE RDBMSIt has been designed as a replacement system for CLICOM and generally follows the look and feel aspects of CLICOM.
19SDCLIM (Tunisia)System designed to specifically to manage data collection for the Tunisia climate data stationsScreen navigation is difficult to follow at times. The metadata structure was sound (Structured around station information) however the data entry and modification is complex.Data output is based on SQL scripts. It is planned to start developing standard output reports using Oracle Reports
20CLIMSOFT (Zimbabwe)Climsoft was the only system that is based, entirely, on MicroSoft software and utilizes the MicroSoft Access RDBMS as the core of the system.Design based on the utilization of readily available software that would lower the cost of ownership and personnel required to manage and maintain the system.Targeted to small meteorological services (The data capacity is currently limited to 2 Gb of data imposed by limits of MS Access.The system was extremely slow access time in comparison with other systems evaluated.
