1. New Climate Databases Management Systems (CDMSs) EXPERT MEETING ON METEOROLOGICAL INFORMATION FOR LOCUST CONTROL
18-20 October 2004, Geneva
Hama 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 deficiencies
Still in DOS
Cannot use different Database Management Systems,
Not a Client / Server System , Internet Connections etc.
No link to Geographical Information Systems (GIS)

3. System Name and Software Release Information

4. New CDMSs

5. Metadata
Elements in the metadata
Possibility to add more elements
Possibility of supporting graphical elements
Information on equipment and instruments

6. Metadata Station name station number/identifier date or date range
latitude/longitude
elevation
country
climate element (temperature, etc)
Maps, photos etc..
other

7. Import of Digital Data
Messages that can be imported (TEMP, METAR, SYNOP, CLIMAT…)
Importation of multiples data files for one station
Importation of multiples data files for multiple stations
Import data from CLICOM

8. Validation and Quality Controls
Quality control flags
Are QC results stored
System offers replacement estimates for fail QC
QC validation
Method of defining ranges values for comparison
Spatial coherence

9. Data Extraction
Training time for data extraction (1 hour, 1 day, more than a day..)
GUI to enter data extraction parameters
Examples for command line queries

10. Type of variables Hourly data Daily data 10-day data
Other (specify in Annex)
Daily summary
10-day, monthly, annual summaries
Extreme values

11. Output Products Tabulated data (hourly, daily, …)
Tabular summary of statistical analysis
Typical 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, ..)

12. CLIDATA (Czech Republic)
Build around the ORACLE RDBMS and associated management and data discovery tools
professionally designed
scalable for use in all sizes of climate data organizations
provides multi-language support and flexible specification of quality control procedures.

13. CLISYS (France)
CLISYS package is built using, primarily, open source software packages
Major 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.

14. CLIWARE (Russian Federation)
CliWare is the most technologically advanced of the systems reviewed
It uses a client-server model that can access data locally or over a network connection to a remote database through an http socket
Communicates 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 ...)

17. Cliware : 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

18. J C D M S (Jordan)
System specifically, to manage data collected from the network of climate data stations in Jordan
Data 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 RDBMS
It has been designed as a replacement system for CLICOM and generally follows the look and feel aspects of CLICOM.

19. SDCLIM (Tunisia)
System designed to specifically to manage data collection for the Tunisia climate data stations
Screen 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

20. CLIMSOFT (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.
