ENACTS: A New Technical

Innovation to Meet Climate

Information Needs

Tufa Dinku

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

Combining station data with proxies: Rainfall


Step 1: Downscale reanalysis product

2. Improving Access: Map Rooms

Data + IRIDL = Information products

Improving Access: Climate Analysis Tool

Improving Access: Climate Monitoring Maproom

From left to right: dekadal rainfall, dekadal rainfall anomaly,

cumulative(since the start of the current season) anomaly, and the

Standard Precipitation Index (SPI)

Improving Access: Climate Monitoring Maproom

Cumulative anomaly:

Jun to Oct(1st dek), 2015

Improving Access: Climate Monitoring Tool

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

OND during El Nino


ii. Translates seasonal forecast from tercile to rainfall amounts

+

3. Improving Use

i. Awareness raising

ii. Training

iii. Involving users in

product generation

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

ENACTS Countries

Next:

Kenya

Uganda

Malawi

Mozambique

ENACTS Countries:

Ethiopia

Gambia

Ghana

Madagascar

Mali

Rwanda

Tanzania

Zambia

III. Next phase

1. Generate daily climate time series

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.

Improving presentation of seasonal forecast
