Climate Information Service

APCC produces high-cost climate data and information by operating a real-time and highly-validated climate prediction system based on a multi-climate model ensemble (MME) technique. APCC also carries out research in order to enhance capacity in the monitoring and prediction of weather and climate in the Asia-Pacific region and beyond. Through APCC, high value climate data and information is shared to our partner countries.  

APCC's climate prediction and monitoring services are expected to assist institutions and societies in managing extreme climate events that currently occur on seasonal and sub-seasonal time scales. This same technology can be seamlessly extended to address the issues associated with long-term climate change induced by greenhouse gas emissions.

Institutional Framework
APCC climate forecasts are based on model simulations from 17 leading climate forecasting centers and institutes in the APEC region and beyond. These forecasts are collected and combined using state-of-the-art schemes to produce a statistically 'consensual' forecast.

The 17 participating institutions in the APCC MME system are the following;

Seasonal Climate Forecast
Multi-Model Ensemble Climate Prediction

The APCC provides real time climate information to APEC economies on a monthly basis through various media, such as internet and direct emailing. The monthly 3-month MME forecast covers three variables: precipitation (PREC), temperature at the 850 hPa level (T850), and geopotential height of the 500 hPa (Z500). The APCC routinely issues this product 10 days prior to the forecast period. For providing a longer lead forecast, APCC also services a six-month coupled MME climate prediction.

In order to ensure the reliability of its climate services, APCC is continuously doing forecast verification against observation. Climate forecasts and verification results can be accessed on website.

Climate Monitoring
The APCC has been producing climate monitoring products and providing them to the APEC member economies through the website and bulletin enclosed in APCC forecast outlook. These products include the latest observed weekly, monthly and seasonal mean values of sea surface temperature (SST), rainfall, outgoing long wave radiation (OLR), surface air temperature, geopotential height at 500 hPa (Z500), surface wind. It also includes tropical Indo-Pacific monitoring, global extreme drought and flood monitoring outputs.

The climate highlight based on the latest approximately 3 months has been accompanied with APCC forecast outlook. In 2009, the real-time automated climate monitoring system has been developed and operationalized. The current status of the latest observed weekly, monthly and seasonal mean values of several variables and tropical Indo-Pacific region and monitoring product of global extreme drought/flood have been published on APCC website.
APCC Data Service System (ADSS)
Established in 2007, the APEC Climate Center Data Service System (ADSS) aims to acquire and disseminate accurate, up-to-date climate data and information. This service is provided by APCC to APEC member economies and interested institutes. ADSS provides a variety of climate information from near real-time climate monitoring data to climate forecasts. The data may be used to monitor evolving climate events, initialize subseasonal to seasonal and longer lead forecasts, create customized forecasts, and facilitate research on sub-seasonal to seasonal climate variability and predictability.

Data colleting platforms
A major motivation in the design of ADSS is to make data access easy for a wide range of forecast user communities. Climate information comes from a variety of sources including forecast models, in situ observation platforms, satellites and climate re-analyses, which are a blend of observational and model data. These different sources usually provide data according to their own conventions and formats. The ADSS strives to reduce complexities associated with such heterogeneous data by conducting suitable post-processing and reformatting. After this, data are available in a single uniform format. In the ADSS system, data is internally stored in the popular NetCDF format.

CLIK:Climate Information Tool Kit
The Climate Information Tool Kit (CLIK), a web-based climate information tool, is motivated by the desire to empower users to take advantage of climate information and forecasts. CLIK aids users in retrieving and utilizing climate prediction data and information available from APCC data servers in a user-friendly manner.

The web interface of CLIK allows users to authenticate, produce the customized MME (Multi-Model Ensemble) seasonal prediction, and make a downscaling forecast for a specific region. The user interface is connected with the computational systems which are Automated Forecast Systems (AFS) and Downscaling Forecast Tool.

Climate forecasters, disaster planners and researchers can login to this online service to create a customized climate prediction for their region of interest.

CLIK won the Grand Prix Award at the 2009 Fukuoka Ruby Award Competition, in which from 78 entries from 8 countries, for its technical merit and potential contribution to society.

TRACE: Tracking Center and Environmental Changes
Virtual Center on Climate Change

TRACE (web portal) aims at creating a virtual platform for scientists and policy makers to convene and discuss various climate change adaptation issues such as policy and governance, technology and innovation, cost and benefits, adaptation in the cities, adaptation in the community level and disaster risk reduction. The long term climate prediction information for the APEC regions and economies can be used various sectors such as health, energy, water supply, farming and to improvise monitoring and prediction of climate variations. TRACE provides an opportunity to discuss current climate events and keep you abreast with the latest climate news and events around the globe.
