DEEPWAVE: Multi-Network Composite Highest Resolution Upper Air Data


This data set contains a composite of the highest vertical resolution (i.e. the “native resolution”) upper air sounding data from all sources for the Deep-Propagating Gravity Wave Experiment (DeepWave).  The composite includes 853 soundings from  five sources around New Zealand and the surrounding ocean:

  • NSF/NCAR Gulfstream-V dropsondes (282 soundings)
  • Australian Bureau of Meteorology radiosondes from Hobart (137 soundings) and Macquarie Island (140 soundings)
  • NIWA (National Institute of Water and Atmospheric Research) radiosondes from Haast, New Zealand (51 soundings)
  • DLR radiosondes from Lauder, New Zealand (98 soundings)
  • NCAR/EOL radiosondes from Hokitika, New Zealand (145 soundings)

Additional information

Data Quality final
  • 1.0 (2016-12-06)
  • 2.0 (2016-12-20):

    This version corrects a temperature dependent dry bias that was present in the Vaisala RD94 dropsonde relative humidity measurements. Both the relative humidity and dew point values have been corrected.

(Only the current version of the data is available to order. If you have questions about a prior version, please email us.)
