The files include following level 1 data: (1) Doppler spectrum moments of all targets (including insects) (2) Doppler spectrum moments of hydrometeors only based on the method by Bauer-Pfundstein and Goersdorf (2007). Radar reflectivity is corrected in the antenna near field. There was no correction applied for attenuation.
Limitations: none
Provenance: Data of JOYCE, processed by IMGK, University of Cologne
Comments: This product was created from MIRA mmclx data files adjusted to the HD(CP)2 data conventions.
Instrument 1
- Source: Metek MIRA36s cloud radar
- Descriptive Instrument location: The Metek MIRA36s cloud radar is installed next to the microwave radiometer on the roof of the ICG-2 building at the Research Center Juelich.
