Data Users Info

The above WMS layers have TIME dimension enabled. New data is added to these layers every 7 days. Available time periods for each layer can be found under the Time Dimension tag in WMS GetCapabilites document provided in the links above.

ArcMap user can add the TIME parameter in the layer properties to access data for a specific time period.

QGIS users can use plugins like temporal and time manager to iterate through different time periods available in the layer.

Programmers using GetMap requests, can add TIME parameter in the request to fetch the data for specific time period. For more information on WMS operations, visit this page https://docs.geoserver.org/latest/en/user/services/wms/reference.html
