Compiled Radar Data Set
 

 

ECMWF-synthesized and observed radar reflectivities for January 1998 (Bretherton et al. 2000, Fig. 9).

 

The file radarhh.nc contains hourly averages of radar data of clouds over the SHEBA ice camp. The vertical levels at which the data are stored are the same as in the lidar depolarization data set (115,205, 295,...,13075m).
