We request a wind radar to obtain reliable databases of atmospheric low layers and, especially, of the boundary layer. This instrument will become part of a set of platforms that we have (microwave radiometer, radar, Ceilometer, etc.), which will get access to complete information._x000D_ The use of the wind radar is guaranteed both by UCIs (consolidated research units) of the University of León that currently have projects and contracts under development, as well as by other national and international groups. The group that presents the proposal maintains collaborations with companies, ICTS (INTA) and numerous relationships with other university groups with which they share projects or collaborations with thematic networks._x000D_ The election of a wind radar has been made analyzing and selecting a series of functionalities among which its scope, mobility and complementarity to the rest of platforms used by us.
