Theoretical and Applied Climatology is dedicated to form an open and interdisciplinary forum that allows for the scientific exchange between climate related disciplines and climatology as part of atmospheric sciences, as well as between climate related spatial and temporal characteristics, like regional climates or boundary layer climates, from all over the globe. Research papers and reviews on issues relevant to the climate system are published, covering the following topics: climate modelling with all trace constituents of the atmosphere and associated feedbacks, climatic change and climate projections, methods of climate related modelling including artificial intelligence (deep learning, machine learning) micro-, meso- and global climate, climate services, communication, adaptation and mitigation of climate change, applied meteorology, biometeorology, building meteorology and technical meteorology eco-climatology with its complex interactions with ecosystems, including aspects of self-organization, stability and ecosystem services, like carbon sequestration or agricultural and forestry products meteorological measurements, including techniques of remote sensing, network analysis and geo-statistics of climate data.
