In the present paper, a review of ERA5, the most recent reanalysy from the European Centre for Medium-Range Weather Forecasts, and its main characteristics is presented, including the different type of available data as well as practical examples of how to download them from the servers. Once a series of parameters having interest in radiopropagation are identified, a summary on models and procedures that could allow estimating atmospheric attenuation caused by gasses, clouds, and rain is provided.]]></p></abstract>
