Partial validation of a lossy compression approach to computing radiative transfer in cloud system‐resolving models

Abstract Cloud system‐resolving models (CSRMs) routinely calculate radiative flux profiles via the Independent Column Approximation (ICA). The ICA applies 1D radiative transfer models (RTMs) to all columns in a CSRM's domain. For this study, the Partitioned Gauss–Legendre Quadrature (PGLQ) method replaced the ICA in a CSRM. The PGLQ applies RTMs to columns, identified with GLQ rules, and distributes their flux profiles to the other columns. …
