Obligations of member states
Member states of the IOC that participate in GLOSS will agree to:
- designate GLOSS National Contacts with the duties as described in Section 7.1. Enable GLOSS Contacts to fulfil their obligations by providing adequate funding and resources to them;
- require their national authorities that operate tide gauge stations within the GCN to provide high frequency data in near-real time and metadata to the GLOSS Sea level station Monitoring Facility;
- require their national authorities that operate tide gauge stations within the GCN and the GLOSSOC to provide preliminary quality-assessed hourly data and metadata to the GLOSS Fast Delivery Data Center at monthly intervals, in accordance with the GLOSS Quality Control Manual →
- require their national authorities that operate tide gauge stations within the GCN, the GLOSSOC, and the GLOSS-LTT to provide final quality assessed high frequency and monthly data and metadata to the GLOSS Delayed Mode Data Centre/PSMSL, or JASL by September of the year following the datayear, in accordance with the GLOSS Quality Control Manual;
- require their national authorities that operate tide gauge stations at non-GLOSS stations to provide monthly data to the PSMSL by September of the year following the data-year, including metadata;
- encourage their national authorities that operate tide gauge stations at non-GCN stations with the capability of near-real time data access to provide high frequency data and metadata to the GLOSS Sea level station Monitoring Facility (this as a complementary set of information to that from GCN sites);
- require GNSS data from receivers at GLOSS sites be transmitted to the GLOSS GNSS Centre at preferably monthly intervals or on daily basis;
- maintain all GLOSS tide gauge stations (tide gauges and GNSS receivers) to GLOSS standards. Propose replacement sites for GCN stations that have a low probability of being maintained to GLOSS standards. Repair malfunctioning GCN stations as soon as possible to avoid data gaps;
- inform the IOC Secretariat of all changes with regard to the state of GLOSS stations, data submission and National GLOSS Contacts. Consult regularly the GLOSS Station Handbook → and provide new details as necessary to ensure that station information is up to date;
- identify sea level products based on GLOSS tide gauge data that would benefit national agencies, and assist with the development, production, and/or distribution of these sea level products;
- participate in and contribute to GLOSS in its widest sense through regional training workshops and programmes, shared technical support, and other activities that serve to fulfil the goals of the GLOSS Implementation Plan.
These obligations are as listed at page 29 of the 2012 GLOSS Implementation Plan.
