      "schema:description": "Estuaries and coastal zones are under influence of both climate variability and human impacts, and it is desirable to assess their water quality state and anomaly events to facilitate coastal management. The virtual buoy system (VBS) is established here to meet such needs through satellite measurements, algorithm development, data product customization, and data sharing.\r\nThe VBS is based on our Virtual Antenna System (VAS) that obtains low-level satellite data and generates higher-level data products using both NASA standard algorithms and regionally customized algorithms in near real-time.\r\nThe VB stations are predefined and carefully chosen to cover water quality gradients in estuaries and coastal waters. The VBS is operated in two ways:\r\n●   It monitors, extracts, and integrates near real-time data into multi-year time series of a variety of water quality parameters which are displayed graphically at weekly and monthly intervals.\r\n●   It checks diffences between weekly and monthly data and compares them with long term climatology allowing it to determine and display varying degrees of positive (reds) and negative (blues) anomalies. These anomalies can be seen on the summary tab of each virtual buoy station, a sample of which is shown below.",
