Cloud radar, micro rain radar, parsivel and pluvio measurements at Ny-Ålesund for 7 Feb 2018, 16 March 2018 and 16 April 2018
Description
This data set contains netcdf files of the University of Cologne's cloud radar MiRAC-A, micro rain radar, parsivel and pluvio installed at the Arctic research site AWPIEV at Ny-Ålesund. Data are available for 3 days: 7 Feb 2018, 16 March 2018 and 16 April 2018.
The MiRAC-A hourly files (“mirac-a_nya_compact_*_P01_ZEN.nc” include (among other variables):
float Ze(time, range) ;
Ze:long_name = "Equivalent radar reflectivity factor Ze" ;
Ze:units = "mm^6/m^3" ;
float vm(time, range) ;
vm:long_name = "Mean Doppler velocity" ;
vm:units = "m/s" ;
vm:comment = "negative values indicate falling particles towards the radar" ;
float sigma(time, range) ;
sigma:long_name = "Spectral width of Doppler velocity spectrum" ;
sigma:units = "m/s" ;
The Micro Rain Radar daily files (“*_nya_mrr_improtoo_0-101.nc”) include (among other variables):
float Ze(time, range) ;
Ze:description = "reflectivity of the most significant peak" ;
Ze:units = "dBz" ;
The parsivel daily files (“sups_nya_dm00_l1_any_v00_*.nc”) include (among other variables):
float N(dclasses, time) ;
N:fill_value = NaN ;
N:units = "log10(m-3 mm-1)" ;
N:long_name = "particle concentration per diameter class" ;
float dclasses(dclasses) ;
dclasses:units = "mm" ;
dclasses:long_name = "volume equivalent diameter class center" ;
The pluvio daily files (“pluvio_nya_*.nc”) include (among other variables):
r_accum_NRT(dim) ;
r_accum_NRT:description = "accumulated precipitation NRT" ;
r_accum_NRT:units = "mm" ;
All available variables are listed and described in the header of the corresponding netcdf files.
