Hydrological and climate monitoring by WMO

Tommaso Abrate, Scientific officer Climate and Water Department

• Decision-making processes need to be supported

by reliable data and information

• Changing precipitation, melting snow and ice

patterns and ETP are altering hydrological systems.

Challenges for Hydrometry

Without data any conjecture is possible,

any model can be proposed, any litigation

can be fostered (R. Rosso; Bisagno, il fiume nascosto, 2014)

Challenges for Hydrometry

• Insufficient capacity of current

monitoring networks

• Long-term data collection

• Lack of good quality data

• Low visibility and recognition of

Hydrological Services

Decline of monitoring networks

Technical Report on Methodology and Lessons Learnt for ECOWAS countries (2017)

Hydrometry networks are essential BUT insufficiently developed

How can WMO help?

Global Hydrological Status and Outlook System

• Simple, easily accessible hydrological information to users

– Current global hydrological status

– Where this is significantly different from ‘normal’

– Where this is likely to get worse

• Adopted in 2016

• Pilot phase over the 2016-2020

• Supported by WHOS, WaterML2.0

WMO Data Exchange Policy

Committed to broadening and enhancing, whenever possible, the free and unrestricted international exchange of data and products necessary for the provision of services in support of the protection of life and property and the well being of all the nations…”, in consonance with the requirements for WMO’s scientific and technical programmes

Innovation domains

• Sensors

• Citizen observatories

• Information systems

• Transforming data and information into knowledge for decision makers

• Open data policy and transboundary data sharing

Standards and Quality Management

• Quality is essential

• Four benefits of QM – Better management and a more

effective organization

– Employee satisfaction and commitment to the organization

– Improving the quality of products and services.

– Improving customer satisfaction and NHS image

Lessons learned from the previous assessment: Different approaches/methodologies complicate regional assessments

Quality Management Framework

Quality Management Framework

• Embedded in all system components

• Impacts on information and knowledge quality

• Strengthen users’s confidence in data, products and services quality

• Makes users aware of inherent uncertainty

• National implementation

• No need for formal certification

• Cost of quality vs cost of lack of it

Conclusions • Data collection is national responsibility

• WMO supports global, regional and national efforts in

hydrology:

– Improved monitoring

– Innovative technologies

– Data management tools

– Quality of data

– Data exchange and sharing . Infrastructure and regulatory framework
