IGAD Climate Prediction and Applications Centre (ICPAC) has been designated as the World Meteorological Organization (WMO) Regional Climate Centre (RCC) of excellence in provision of climate services to national and regional users.

IGAD Regional Climate Centre (IGAD-RCC), continues to provide regional climate forecasts and other products that support regional and national climate activities, and thereby strengthen the capacity of WMO Members in the Greater Horn of Africa region to deliver better climate services to users.

Mandatory RCC Functions
WMO RCCs perform the following set of mandatory functions covering the domains of long-range forecasting (LRF), climate monitoring, data services and training.

Operational Activities for Long-range Forecasting
Interpret and assess relevant LRF products from GPCs, distribute relevant information to RCC Users, and provide feedback to GPCs. Generate regional and sub-regional tailored products, relevant to RCC user needs, including seasonal outlooks etc. Perform verification of RCC quantitative LRF products, including the exchange of basic forecast and hindcast data. Generate consensus statement on regional or sub-regional forecasts.

Operational Activities for Climate Monitoring
Perform climate diagnostics including analysis of climate variability and extremes, at regional and sub-regional scales. Establish a historical reference climatology for the region and/or sub-regions. Implement a regional climate watch.

Operational Data Services, to support operational LRF and climate monitoring
Develop quality controlled regional climate datasets, gridded where applicable. Provide climate database and archiving services.

Training in the use of operational RCC products and services
Provide information on methodologies and product specifications for mandatory RCC products, and provide guidance on their use. Coordinate training for RCC Users in interpretation and use of mandatory RCC products.
Additional Highly Recommended Functions
Climate Prediction and Climate Projection (beyond 2 years’ timeframe)
  • Assist RCC Users in the access and use of WCRP-CMIP climate model simulations
  • Perform downscaling of climate change scenarios
  • Provide information to RCC Users for use in development of climate adaptation strategies
  • Generate, along with warnings of caution on accuracy, seasonal forecasts for specific parameters where relevant, such as:
  • onset, intensity and cessation of rainy season;
  • tropical cyclone frequency and intensity
  • Perform verification on consensus statements for forecasts;
  • Perform assessment of other GPC products such as SSTs, winds, etc.

Non-operational data services
  • Keep abreast of activities and documentation related to WMO WIS, and work towards WIS compliance and DCPC designation;
  • Assist NMHSs in the rescue of climate data from outmoded storage media;
  • Assist NMHSs to develop and maintain historical climate datasets;
  • Assist RCC Users in the development and maintenance of software modules for standard applications;
  • Advise RCC Users on data quality management;
  • Conduct data homogenization, and advise RCC Users on homogeneity assessment and development and use of homogeneous data sets;
  • Develop and manage databases, and generate indices, of climate extremes;
  • Perform Quality Assurance/Quality Control on national datasets, on request of an NMHS;
  • Provide expertise on interpolation techniques;
  • Facilitate data/metadata exchange amongst NMHSs, including on-line access, through an agreed regional mechanism;
  • Perform Quality Assurance/Quality Control on regional datasets.

Coordination Functions
  • Strengthen collaboration between NMHSs on related observing, communication and computing networks including data collection and exchange;
  • Develop systems to facilitate harmonisation and assistance in the use of LRF products and other climate services;
  • Assist NMHSs in user liaison, including the organisation of climate and of multidisciplinary workshops and other forums on user needs;
  • Assist NMHSs in the development of a media and public awareness strategy on climate services.

Training and Capacity building
  • Assist NMHSs in the training of users on the application and on implications of LRF products on users;
  • Assist in the introduction of appropriate decision models for end-users, especially as related to probability forecasts;
  • Promote technical capacity building on NMHS level (e.g. acquisition of hardware, software, etc.), as required for implementation of climate services.
  • Assist in professional capacity building (training) of climate experts for generating user-targeted products.

Research and Development
  • Develop a climate Research and Development agenda and coordinate it with other relevant RCCs;
  • Promote studies of regional climate variability and change, predictability and impact in the Region;
  • Develop consensus practices to handle divergent climate information for the Region;
  • Develop and validate regional models, methods of downscaling and interpretation of global output products;
  • Promote the use of proxy climate data in long-term analyses of climate variability and change;
  • Promote application research, and assist in the specification and development of sector specific products;
  • Promote studies of the economic value of climate information.
