Ensemble Riemannian Data Assimilation over the Wasserstein Space
Sagar K. Tamang, Ardeshir Ebtehaj, Peter J. Van Leeuwen +2
In this paper, we present an ensemble data assimilation paradigm over a Riemannian manifold equipped with the Wasserstein metric. Unlike the Eulerian penalization of error in the E…
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…
