Machine Learning-Augmented 3D-Variational Data Assimilation for Wintertime Diurnal Variability of Surface Ozone Over China

Accurate surface ozone (O3) estimates are critical for mitigating air pollution and developing strategies. However, efforts of using data assimilation (DA) to improve O3 simulation have been hindered by limited observations. Here, we develop the first hourly, multispecies machine learning-augmented three-dimensional va...
