GEO 2017-2019 Work Program

 

In-Situ Observations and Practices for the Water Cycle

Activity ID: 99

Overview

Participants of the 12th session of the Integrated Global Water Cycle Observations (IGWCO) Community of Practice (CoP) had proposed a plan for the reduction of GEO Community activities and proposed a new Community Activity (CA) combining several existing activities contained in the transitional GEO 2016 Work Programme. The new CA should include the following CAs from the 2016 Work Programme: CA-11 (Soil Moisture), CA-12 (Streamflow), CA-13 (Groundwater) and a new activity: Surface Water Storage (to be developed). The new CA is proposed to address a variety of issues related to variable-specific activities, hence the more inclusive title.

Terrestrial in-situ observations including soil moisture, streamflow and groundwater in addition to other Essential Water Variables that are identical to Essential Climate Variables of the Global Climate Observation System (GCOS) are coordinated by the Global Terrestrial Network – Hydrology (GTN-H). GTN-H as a federated network of global data centres has continuously served as the in-situ observations component of IGWCO since its inception.

As a new CA affiliated with the GEOGLOWS Initiative, this CA is in a development phase that will contribute to the GEOGLOWS program framework and especially to activities 3 (Essential Water Variable Understanding), 4 (Earth Observations, Integrated Data Products and Applications, and Tool Development) and 5 (Data Sharing, Dissemination of Data, Information, Products, and Knowledge).

Activities for the period

The focus of plans and activities is geared to consult with shareholders of the new CA and to agree on a viable work plan in support of GEOGLOWS. This will be achieved through direct consultations with the International Soil Moisture Network (ISMN), Global Runoff Data Centre (GRDC) and International Groundwater Resources Assessment Centre (IGRAC) as well as through existing entities notably through GTN-H. The development of a sub-CA on Water Storage has a special priority to ensure timely close-up with already existing traditional CAs including the aforementioned ISMN, GRDC and IGRAC and in cooperation with potential custodians including the Global Database on Lakes and Reservoirs (HYDROLARE) and others, to be identified.

In particular:

  • Data will be registered in the GEO Common Infrastructure (GCI) as well as in WMO´s Integrated Global Observing System/Information System (WIGOS/WIS) Platform (both are now designed to be interoperable to avoid duplication of efforts);
  • Dissemination of data will take place in accordance with established data policies;
  • Best practices will be used for the long-term storage of data and meta-data in state-of-the-art database systems and the application of rigorous data quality checks;
  • Standards will continue to be developed/refined to ensure interoperability of data structures and archives;
  • Analysis of data and the development of products need to be undertaken in a two-tiered approach: Provision of first order data analysis products that may be largely automated and tailored on-demand products that may require extra-budgetary resources;
  • Close linkage will be kept between the new CA, focusing on in-situ observations and its satellite component through cooperation/coordination with the Committee on Earth Observation Systems (CEOS).

User Engagement

Whereas former CAs 11-13 already have active user communities, the new Water Storage CA will include user communities of CAs 11-13 and additional users such as those using HYDROLARE services. Broad-scale communication of the In-Situ Observations and Practices for the Water Cycle CA is expected to draw new users. Enhanced engagement of users will be achieved through a participatory approach for the development of products and services, sharing of user requirements and participation in community activities such as through teleconferences, dedicated workshops and other means of interactive sharing of requirements, requests and practices.

Future plans

To provide general and specific, as well as selected tailor-made services to the GEOGLOWS program framework activities 3,4 and 5 through the provision of data provided in standard formats to users including dissemination in accordance to agreed data policies, upkeep of data archives, and the further development of standards in cooperation with the Open Geospatial Consortium (OGC) and WMO.

Resources

At present there are no extra-budgetary funds available to develop and operationalize the CA. All resources are provided on the basis of in-kind contributions and derivatives from activities already under planning and/or implementation by CA partners. The new activity on surface water storage needs to be developed on voluntary inputs from leads and contributors still to be identified.
