Summary
HIAPER Cloud Radar (HCR) data collected aboard the NSF/NCAR GV HIAPER
(Gulfstream-V High-performance Instrumented Airborne Platform for
Environmental Research, HIAPER) (N677F) during OTREC (Organization of Tropical
East Pacific Convection). The data were collected during 22 research flights
which took place between August 7 and October 2, 2019, over the East Pacific
and extreme SW Caribbean Ocean.

Versions
  0.1: Version 0.1 is the raw field data.
  1.0: Quality controlled final data set.
  2.0: Radar variables stayed the same. Model variables were upgraded to ERA5
(instead of ECMWF forecasts).
  2.1: Freezing level data field was added.
  2.2: Freezing level was replaced with melting layer field. Icing level was
added.
  3.0: De-aliased velocity, convective/stratiform echo type, and particle
identification were added.
  3.1: In the particle identification field (PID), liquid particles are no
longer allowed at temperatures below -40 C.
  3.2: Improved echo type and melting layer fields.
