Transcript of ENACTS: A New Technical Innovation to Meet Climate Information Needs
Outline
I. What is ENACTS?
1. Improving Data Availability 2. Enhancing Access to Climate Information
3. Promoting the Use of Climate Information
II. Major Outputs
III. Next Phase
I. The ENACTS Approach
• ENACTS = Enhancing National Climate Services
• Strives to simultaneously improve availability, access
and use of climate information.
• Works with NMHS to quality-control all available
station data and combine them with satellite and
reanalysis products.
• The main focus of ENACTS is creation of reliable
climate information products for local decision-
making.
The Three Pillars ENACTS
Improve Availability
• Build capacity of NMHS
• Quality Control station
data
• Combine station data
with proxies
• Improve seasonal
forecast
E N A C T S
Enhance Access
• Install IRI Data
Library
•Develop online tools
for data analysis and
visualization
• Create mechanisms
for data sharing
Promote Use
Engage users:
• Raise awareness
• Build capacity of
users to understand
and use climate info
• Involve users in
product development
1. Improving Data Availability
i. Assessing Data Availability This has helped the NMS look at their data in a completely different way
Improving Data Availability
Station Satellite
Combined
Combining station data with proxies: Rainfall
Reconstructing Climate Time Series
Step 1: Downscale reanalysis product
Combining station data with proxies: Temperature

Step 2: Combine station
observation with downscales

Improving Access: Climate Monitoring Maproom

cumulative(since the start of the current season) anomaly, and the
Standard Precipitation Index (SPI)

Improving Access: Climate Forecast Tool
i. Explore potential impacts of ENSO/IOD phases
Probability of wet OND season during El Nino

i. Explore potential impacts of different ENSO/IOD
phases on rainfall: Historical ENSO Events

ii. Translates seasonal forecast from tercile to rainfall amounts

II. Major Outputs
• Over 30/50-years of climate time series for every 4km
grid across each country:
o Now data available where there are no stations
• Installation of the IRI Data Library at NMHS
o A powerful tool for generating climate information
• Unprecedented online access to information products:
o Satisfies the needs of many users
o Overcomes (partly) the challenges of data access
• Built capacity at NMHS and some user communities

Next phase
3. Add sector-specific Maprooms: Agriculture, Water,
Disaster, Health, …
2. Add more climate variables (RH, PET/ET, sunshine…)
4. Improve accuracy and presentation of seasonal
climate prediction
• Evaluate;
• Improve;
• Implement.
