DATA RESCUE IN AFRICA: SYNERGY WITH NATIONAL AND REGIONAL PROJECTS Climate&Environment Department ACMAD International Workshop on the Rescue and Digitization of Climate Records for countries in West Africa 19-23 November 2012, Accra, Ghana
OUTLINE • Historical Background • ACMAD plans for African Data Rescue& Management • Proposed support to other DARE projects in Africa • Concluding Remarks
HISTORICAL BACKGROUND • With funding from Belgium, WMO sent experts in 46 African countries to locate and image hydromet data • Microfiches of over 30 millions old observations from about 1000 sites were produced with copies to countries • Microfiches were handed over to ACMAD around the • mid 90s • Discussions with IEDRO and recently with IRI at Columbia University for imaging and digitalization • Call for bid and selection of a firm to procure data rescue equipments and related training at ACMAD • ( Aug-Oct 2012)
ACMAD DATA RESCUE PLANS • Training of ACMAD/country experts on scanning of microfiches, creation of images library , data keying and entry into the national and continental databases • Inventory , scan all microfiches ( about 100 thousands) and save as digital images • Key in the data and enter them into the ACMAD/Regional Climate Centre’s African climate database
ACMAD DATA RESCUE PLANS ( support to country and sub-regional DARE projects) • Provide on the job training on data rescue at ACMAD for countries • Countries data Rescue with seconded experts and visiting scientists programmes at ACMAD Each country expert will bring back a copy of digitized Data in a Climsoft managed database interfaced with application tools ( RCLIMDEX, CPT, Excell, GIS macros…) for climate monitoring and forecasting products • Organize workshops to produce climate indices, Atlases and other added value products using rescued data
DEVELOPMENT AND USE OF THE CONTINENTAL CLIMATE DATABASE AT ACMAD • Data base design and architecture • Ingestion of Daily Data • Ingestion of Synoptic data • Curent status of the Data base
DATA BASE DESIGN AND ARCHITECTURE • Data model is the model for CLIMSOFT version 3, which was last updated in 2010 • Data model allows storage of different data formats: numeric, text, Boolean (Yes/No) and graphical images • Though originally designed in MS Access, the database design has been ported to MySQL and PostgreSQL. It can be ported to any other RDBMS. • For the ACMAD climatological database, the open source PostgreSQL was chosen for its efficiency, stability and robustness. • PostgreSQL data storage capacity is on the order of Terabytes (TB).
INGESTION OF DAILY SYNOP DATA • CLIMSOFT ingest GTS data via FTP. • The data are automatically imported into the CLIMSOFT database at a scheduled time. • This module for the ingestion of synoptic data became operational in June 2012.
Current Database Status • Historical daily data from the NOAA/NCDC FTP site date back to 1972. • GTS SYNOP data imported from GTS data reception system at ACMAD. • Total database size is approximately 24 GB • Very Basic QC is carried out. We are planning to implement more rigorous Quality checks.
PROVISION OF FORMATED DATA FOR CLIMATE OPERATIONS • Table of 10-day summaries for selected stations for all Africa input to dekadal Bulletins • Data output in RClimDex, CPT and Instat inputs formats. • We have plans to include other outputs in formats required by any climate application tool
African RCC data services Products • Long-term climatological means generated for all GTS stations in Africa. • Climatological means available for the period 1981-1990, 1991-2000, 2001-2010, 1981-2010. • Data products in XML format and can be viewed with any web browser
RCLIMDEX and INSTAT input data format from Chad climsoft Database at ACMAD
SAMPLE PRODUCTS EXPECTED FROM A DATA BASE AND APPLICATION SERVERS
CONCLUSION • Multiple key entry for countries data using on the job training, secondment and visits on data rescue to reduce possible errors • Continue development of CLIMSOFT for station data by building interfaces with the web, application tools, other environmental database management systems as well as GIS software • Expand CDMS training across Africa integrated into workshops for generating value added information for climate data
