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.

  • 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.

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