Selected Landsat 7 through 9 Surface Reflectance Scenes for the Thwaites Glacier
cryosphere NASA VEDA COG
In plain English

What it measures. Clear satellite images of the Thwaites Glacier in Antarctica, chosen for low cloud cover.

How it's made. From Landsat 7, 8, and 9 satellite imagery, combined across missions for natural-color views.

How & where you'd use it. Lets scientists monitor this vulnerable 'doomsday' glacier and its contribution to sea-level rise.

Official description

Selected low-cloud-cover Landsat Collection-2 Level-2 Surface Reflectance scenes covering the Thwaites Glacier. Products from multiple missions and instruments are combined in this single collection for the purpose of visualizing RGB images. Note that the full item records are not interchangeable across instruments for purposes other than visualization and that the assets available are not the same for each instrument.
