Introducing non‐Gaussian observation errors into incremental variational data assimilation methods

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We propose a new method, called the evolving‐Gaussian method, to incorporate non‐Gaussian observation error into data assimilation methods that use Gauss–Newton‐based outer loops. The key idea is to approximate the gradient of the non‐Gaussian cost function locally by using a chosen Gaussian cost function during the minimization.

Impacts of atmospheric river reconnaissance dropsondes on ECMWF Integrated Forecasting System precipitation forecasts

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Impacts of Atmospheric River Reconnaissance dropsonde observations on precipitation forecasts over the U.S. West Coast are examined in the European Centre for Medium‐Range Weather Forecasts (ECMWF) Integrated Forecasting System (IFS), using observing‐system experiments.
