Map of elevation changes: quick-looks

28 mars 2024

The ultimate PGO products are the maps of glacier elevation changes over 5-yr periods. They will soon be available on a web server. To keep you waiting, find below a gallery of such maps for 2016-2021, 2017-2022 or 2018-2023. Maybe you can spot your favorite glacier? [click on the first image to start the slideshow]

Beyond Pléiades. 4D-Earth ?

Pléiades will be flying until 2026, maybe slightly later. Another key stereo mission, ASTER on-board TERRA, will stop acquiring images in 2026 or 2027. A large scientific community (in particular glaciologists) is worried about the lack of follow up stereo missions. See here a Letter to the Editor in Nature. This is why we propose […]

PGO data help to guide fieldwork in the Andes

We are delighted to read that Pléiades ortho-images and DSM were useful to guide a recent field campaign on the Quelccaya Ice Cap. PGO data will certain be also useful for the science to come out of these field observations. Congrtulation to the Deplete and Retreat: Andes Water Towers team.

Mandal et al.: Glacier mass balance and its climatic and nonclimatic drivers in the Ladakh region during 2000–2021 from remote sensing data

Ladakh region in the western Himalaya relies heavily on meltwater from glaciers and snow covers, particularly during spring season and dry years, due to its arid climate conditions. In our recently published paper (reference below), we estimated the geodetic mass balance of nearly all Ladakh glaciers using SRTM and ASTER DEMs for the period 2000-2021. […]
