NHI-A SYSTEM TO MAP VOLCANIC THERMAL ANOMALIES FROM SPACE

The NHI (Normalized Hotspot Indices) system performs the automated monitoring of volcanic thermal anomalies under the Google Earth Engine (GEE) platform, using data from the Multispectral Instrument (MSI) and the Operational Land Imager (OLI), aboard Sentinel-2 and Landsat-8/9 satellites.

The system searches for thermal anomalies over active volcanoes as soon as Sentinel 2 / Landsat 8/9 scenes are ingested in GEE (this may affect the number of automated notifications).

False positives may occur mainly because of multispectral misregistration of Sentinel-2 MSI imagery and fires.

Please, wait while the system searches for thermal anomalies ..
