Dynamic input file

The dynamic input file (see PIDS_DYNAMIC) comprises all data which might change depending on the day of year, such as initialization data, large-scale forcing tendencies or boundary data. Utilizing the pre-processing tool INIFOR, the respective data can be derived directly from the larger-scale ​COSMO model (except for active or passive chemical components which are not considered in the COSMO model). This way, the dynamic input file acts as a interface between a larger-scale model and PALM, being a so-called offline nesting?. In case of a nested? model run (online), only the parent domain considers the dynamic input_file for inititialization and offline-nesting, while embedded child models itself will be initialized and forced via its parent domains. In order to activate input from the dynamic input file, setting of initializing_actions? = 'inifor' is required. For more information of how to create a dynamic input file, please see the INIFOR documentation. For more detailed documentation of the input variables, please see PALM input data standard.
