Cloud radar, micro rain radar, parsivel and pluvio measurements at Ny-Ålesund for 7 Feb 2018, 16 March 2018 and 16 April 2018

  • 1. University of Cologne

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.
