CSET: Low Rate (LRT - 1 sps) Navigation, State Parameter, and Microphysics Flight-Level Data

Summary

This dataset includes airborne measurements obtained from the NSF/NCAR GV HIAPER (Gulfstream-V High-performance Instrumented Airborne Platform for Environmental Research) (N677F) during the CSET (Cloud System Evolution in the Trades) project. This dataset contains low rate navigation, state parameter, and microphysics flight-level data in netCDF format.

Versions
  • 1.0 (2015-08-21):

    Initial, final QC'd data

  • 0.1 (2015-08-21):

    Preliminary (field-phase) data. Password required for access.

  • 1.1 (2016-04-18):

    Add 2DS data inadvertently left out of original release.

  • 1.2 (2017-05-09):

    Add three variables: A1DC_LWOO, AUHSAS_RWOOU, ACDP_LWOI and update RSTB.

  • 1.3 (2018-10-18):

    This update contains corrected 2DC data (variables ending in _LWOO) and 2DS data ( _3H and _3V). No other data has been changed. It was discovered that all particles in a single buffer got time-stamped with the data-system time tag of the end off the buffer. So for concentrations above 5-10/L, or when in heavy cloud, the system writes multiple buffers per second so the time-stamp will be very close to accurate. But when a buffer spans multiple seconds, all the particles were being binned to the second of the end time-stamp for the buffer. This has now been corrected so data is spread across the time-period of the buffer correctly. This version also uses exact circle fitting for measuring particle size and limits accepted particles to center-in images.

  • 1.4 (2022-03-14):

    Merge of HOLODEC binned concentration and particle count data.
