Assessing the use of satellite products from multispectral unmixing and differential interferometry for Altay snow water equivalent estimation

Yiwen Fang, Jinmei Pan, S. A. Margulis, Jingtian Zhou et autres

Abstract. This work evaluates the application of fractional snow covered area (fSCA) derived from Harmonized Landsat Sentinel (HLS) multi-spectral images and snow products derived from Sentinel-1 and LuTan-1 interferometric Synthetic Aperture Radar (InSAR) pairs, in generating snow water equivalent (SWE) at the …

Abstract. Active microwave measurements, including those using interferometric synthetic aperture radar (InSAR) techniques, have shown promise for characterizing seasonal snowpacks at high spatial resolution. This study demonstrates a Bayesian InSAR phase data assimilation framework for estimating snow water equivalent (SWE) changes (dSWE) …

Interferometric Synthetic Aperture Radar (InSAR) for Monitoring Seasonal Snow

Jack Tarricone, Ross T. Palomaki, Randall Bonnell, Zachary Hoppinen et autres

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 …

Assessing the impact of meteorological forcing and its uncertainty on snow modeling and reanalysis

Haorui Sun, S. A. Margulis

Abstract. Large uncertainties in global model-based snow datasets, particularly in snow water equivalent (SWE), limit our understanding of snow storage and its response to climate change. These uncertainties are sensitive to meteorological inputs used to force offline snow models. In this study, …

A data assimilation framework for improving greenland ice sheet surface mass balance using simulated gridded ICESat-2 elevation change data

Mahdi Navari, C. Max Stevens, Brooke C. Medley, Denis Felikson et autres

Abstract The ongoing melting of the Greenland ice sheet (GrIS) is a major contributor to global sea-level rise. Accurately quantifying this contribution requires reliable estimates of surface mass balance (SMB), yet substantial discrepancies persist among existing estimates due to observational limitations and …
