Low Rate (LRT - 1 sps) Navigation, State Parameter, and Microphysics
Flight-Level Data - ICARTT format
https://data.eol.ucar.edu/dataset/490.010

Summary
This data set includes airborne measurements obtained from the NSF/NCAR HIAPER
GV aircraft (Tail Number N677F) during the ORCAS (The O2/N2 Ratio and CO2
Airborne Southern Ocean Study) project. This dataset contains low rate
navigation, state parameter, and microphysics flight-level data in ICARTT
format.

Versions
  0.1
  0.2: New files for all flights (include TF) with 2DC vars instead of 1DC
  1.0: Final version includes Ht above terrain vars
  1.1: Version 1.1 has corrected 2DC data (variables CONC2DCA_LWO,
DBAR2DCA_LWO, and PLWC2DCA_LWO). No other data has been changed. It was
discovered that all particles in a single buffer were 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 previously binned
to the second of the end time-stamp for the buffer. This has now been
corrected so data is timestamped across the time-period of the buffer
correctly. In addition, V1.1 changes 2D processing from reconstruction
to center-in.
