GPM Transitioning its Web-based Global Displays
Google Earth access for near-realtime IMERG and 3B42 KML files will be replaced by an updated service for viewing precipitation data in near-real time on a 3D virtual globe using Cesium (https://cesiumjs.org/).
The current plan is to make the cut-over to the new Cesium-based service on or about October 16, 2016.
The evolution of network policies and applications prevents continued GPM use of Google Earth.
If you wish to continue using KML files with a non-Google Earth client, please contact the Precipitation Measurement Missions at: https://pmm.nasa.gov/contact
