WHOS implementation in the Arctic basin

The real-time and historical hydrological data for the Arctic basin are now available through the WMO Hydrological Observing System (WHOS), and can be visualized and downloaded through the WHOS-Arctic web portal.

The WHOS-Arctic web portal is implemented using ArcGIS Online for the map interface and USGS GWIS (Graphing Water Information System) for the time-series plots.
