Short summary
Solar tides in the atmosphere are driven by solar heating on the dayside of the Earth. They result in large-scale periodic motion of the upper atmosphere. This motion can be measured by ground-based radars. This paper shows that making measurements at a higher time resolution than the standard operation provides a better description of higher-frequency tidal variations. This will improve the inputs to empirical atmospheric models and the benefits of data assimilation.
