The Global Freshwater Quality Database GEMStat provides scientifically - sound data and information on the state and trend of global inland water quality

. Its objectives include collecting, controlling and providing water quality monitoring data and products for regional and global water quality assessments. The Data Centre

maintains the global water quality database and information

system GEMStat. Data for GEMStat is received from GEMS/Water's global network of National Focal Points (NFP's) which are government institutions and agencies with the official mandate to monitor freshwater quality data in their country. 

Data related activities of GEMS/Water include:

• Collecting water quality monitoring data: The Data

  Centre

  Center compiles environmental water quality data from the GEMS/Water Global Network of governmental and collaborating organisations covering more than 80 countries.

• Controlling and assuring data quality: A global dictionary of Analytical Methods for Environmental Water Quality (AMD) and state-of-the-art checks ensure the provision of quality-controlled

  datasets

  data-sets and derived products.

  Visualising

Visualizing and

analyzing data: A web-based information system gives access to statistical and graphical analysis of the data at single sampling sites, aggregated by countries and catchment.

Harmonizing and

standardizing monitoring data exchange: The Data

Center supports the development and implementation of open,

standardized exchange formats for monitoring data and metadata to improve the exchange of data at national and international levels.

Enhancing data

discover-ability and accessibility: The

Center works towards

enhancing the availability and accessibility of GEMStat data and products by integrating them into existing global environmental information systems (Environment Live, GEOSS).
