Interferometric Synthetic Aperture Radar (InSAR) for Monitoring Seasonal Snow

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Interferometric Synthetic Aperture Radar (InSAR) offers a potential pathway for measuring seasonal snow water equivalent (SWE) and snow depth at spatial and temporal scales needed for basin‐scale hydrology. First proposed for seasonal snow more than 25 years ago, InSAR uses repeat‐pass radar phase differences to estimate changes in SWE or ...

Assimilation of Atmospheric CO2 Concentration in the ORCHIDEE Land Surface Model: Exploring the Added Value of Explicit Forest Regrowth Representation

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract The land absorbs a large proportion of human‐induced carbon emissions, yet the spatial distribution of this carbon sink remains uncertain. Land surface models (LSMs) and atmospheric inversions often diverge on the spatial distribution of carbon sink, with models generally underestimating the northern land sink (above 30°N).
