The Cold-Air Outbreaks in the Marine Boundary Layer Experiment model-observation intercomparison project (COMBLE-MIP) – Part 1: Model specification, observational constraints, and preliminary findings

Models struggle to represent the coupled microphysical, turbulent and radiative processes within widespread, long-lived marine cold-air outbreak (CAO) cloud fields, contributing to forecast and climate biases. Here we combine ground-based and satellite measurements to initialize...

Accelerated Alternating Minimization Algorithm for Low‐Rank Approximations in the Chebyshev Norm

ABSTRACT Nowadays, low‐rank approximations of matrices are an important component of many methods in science and engineering. Traditionally, low‐rank approximations are considered in unitarily invariant norms; however, recently element‐wise approximations have also received signi...
