HIPPO5: Low Rate (LRT - 1 sps) Navigation, State Parameter, and Microphysics Flight-Level Data [NCAR/EOL]

Summary

This data set includes airborne measurements obtained from the NCAR Research Aviation Facility (RAF) Gulfstream V (HIAPER) aircraft (Tail Number N677F) during the HIAPER Pole-to-Pole Observations (HIPPO) of Carbon Cycle and Greenhouse Gases Study Phase 5 (HIPPO-5) project. This dataset contains low rate navigation, state parameter, and microphysics flight-level data in netCDF format.

  • 1.0 (2012-05-16)
  • 2.0 (2016-07-28):

    The NCAR/EOL Research Aviation Facility has recently completed a review and upgrade of its existing algorithms for data processing to incorporate recent improvements that have become available for specific instruments. HIPPO-5 LRT data have been reprocessed and rereleased with these new upgrades.


  • 3.0 (2019-01-25):

    This update contains corrected 2DC data (variable names ending in _LWIO) from processing introduced in Version 2.0. 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. 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. 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.
