High resolution terrestrial water storage changes from combination of GRACE and models

High resolution terrestrial water storage changes from combination of GRACE and models

The Gravity Recovery and Climate Experiment (GRACE) satellite mission (2002-2017) consisted of two satellites at ~500 km altitude separated by 200 km, following each other in the same orbit. The distance between the two GRACE satellites changes because of the gravitational pull of the masses beneath the satellites. As such, mass changes at or near the Earth’s surface caused variations in the dista ...[Read More]

Calculating postglacial sea-level change within few seconds: a statistical emulator for GIA

Calculating postglacial sea-level change within few seconds: a statistical emulator for GIA

Sea-level change serves as a direct indicator of climate change with profound implications for coastal areas. Since 1900, the global mean sea level (GMSL) has risen over 20 cm, leading to beach erosion, delta inundation, and increased flooding worldwide. Over glacial cycles spanning tens of thousands of years, interactions between ocean and continental-scale ice sheets can cause GMSL to fluctuate ...[Read More]
