Future-proofing ice measurements from space [link]
“To ensure that ESA and NASA are getting the best out of their ice-measuring satellites and to help prepare for Europe’s new CRISTAL satellite, the two space agencies along with the British Antarctic Survey and a team of scientists teamed up recently to carry out an ambitious campaign in Antarctica.”
Giant iceberg breaks away from Antarctic ice shelf [link]
“Satellite imagery confirms an enormous iceberg, around five times the size of Malta, has finally calved from Antarctica’s Brunt Ice Shelf. The new berg, estimated to be around 1550 sq km and around 150 m thick, calved when the crack known as Chasm-1 fully extended northwards severing the west part of the ice shelf.”

Next up to Continue NASA/USGS’s Landsat Legacy [link]
“With a trio of smaller satellites that can each detect 26 wavelengths of light, the Landsat Next mission is expected to look very different from its predecessors that have been observing Earth for 50 years. This new plan for Landsat Next, a joint mission of NASA and the U.S. Geological Survey, is designed to provide more frequent, and finer resolution, data of the changing surface of Earth.”
Landsat Next is planned to launch by late 2030.

How to Co-Register Temporal Stacks of Satellite Images [link]
“Geometric errors cause misalignments between consecutive satellite image acquisitions, which in turn impair land monitoring and change detection analysis. In this blog, the EO Research group of Sentinel Hub investigates how we can robustly co-register a temporal stack of optical satellite images to reduce the impact of such misalignments.”

SDUST2020 MSS: a global 1′ × 1′ mean sea surface model determined from multi-satellite altimetry data [link]
“A new global mean sea surface (MSS) model, named the Shandong University of Science and Technology 2020 (SDUST2020), with a grid size of 1'x1' . This new model was established with a 19-year moving average method and fused multi-satellite altimetry data over a 27-year period (from January 1993 to December 2019).”
