PALM-meteo 2.6: Processor of PALM meteorological input data

Abstract. PALM is a versatile and modular microscale atmospheric modelling system. It supports offline nesting using pre-processed initial and boundary conditions, which are provided via the dynamic driver file, along with other time-dependent input data, such as radiative forcing. PALM-meteo is a new modular tool for preparing the PALM dynamic drivers using data from various mesoscale or global meteorological models as well as other sources, such as measurements. It is derived from an older tool, the WRF_interface, which provided dynamic drivers from the WRF model data. PALM-meteo significantly expands the scope of usable meteorological inputs for PALM, and it is ready to be easily extended with more data sources in the future.

Short summary
PALM is a highly versatile open-source microscale atmospheric modelling system. One of its most useful applications is modelling detailed street-level urban climate, e.g. for evaluation of climate change adaptation and mitigation measures in cities. However, to produce real-case microscale simulations, they need to be forced by real or realistic weather conditions. The presented tool enables PALM to use meteorological inputs from a large selection of meteorological models and other sources.
