Images are sorted by acquisition time, with the most recent acquisition on top.
Sentinel-1 images:
- amplitude: back-scattered radar amplitude (VV polarization); date refers to acquisition time (UTC).
- interferogram: phase difference between 2 consecutive acquisitions; "dt" = time difference between master/slave images.
- coherence: interferometric coherence
Sentinel-2 images:
- infrared: combination of shortwave infrared bands B12-B11-B8A; the date refers to the acquisition time (UTC), the time difference displayed is calculated with respect to the nearest Sentinel-1 acquisition (+/- n days). A Sentinel-2 image is "paired" with a Sentinel-1 image (i.e., displayed on the same row) if the acquisition time difference is < 5 days. Click button "toggle" to hide/show unpaired Sentinel-2 images.
Sentinel-5P images:
Because the acquisition rate of Sentinel-5P is significantly different to that of Sentinel-1 and -2 (i.e., 1 day versus 6-12 days respectively), the SO2 images are not displayed in this image grid. See "Image Player" page instead.
Warning: "Kilauea rift-zone " is monitored only during lateral eruption, and up to 1 year after the end of the eruption. Checkout
Kilauea webpage for continuous monitoring of the summit craters.
