Regularized Variational Data Assimilation for Bias Treatment using the Wasserstein Metric
Sagar K. Tamang, Ardeshir Ebtehaj, Dongmian Zou +1
This paper presents a new variational data assimilation (VDA) approach for the formal treatment of bias in both model outputs and observations. This approach relies on the Wasserst…
On Changes of Global Wet-bulb Temperature and Snowfall Regimes
Sagar K. Tamang, Ardeshir M. Ebtehaj, Andreas F. Prein +1
To properly interpret the observed shrinkage of the Earth's cryosphere it is important to understand global changes of snowfall dominant regimes. To document these changes, three d…
A Nested K-Nearest Prognostic Approach for Microwave Precipitation Phase Detection over Snow Cover
Zeinab Takbiri, Ardeshir Ebtehaj, Efi Foufoula-Georgiou +2
Monitoring changes of precipitation phase from space is important for understanding the mass balance of Earth's cryosphere in a changing climate. This paper examines a Bayesian nea…
Non-Smooth Variational Data Assimilation with Sparse Priors
Ardeshir M. Ebtehaj, Efi Foufoula-Georgiou, Sara Q. Zhang +1
This paper proposes an extension to the classical 3D variational data assimilation approach by explicitly incorporating as a prior information, the transform-domain sparsity observ…
