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 Tropical Ocean tRoposphere Exchange of Reactive halogen species and Oxygenated VOC (TORERO) project. This dataset contains low rate navigation, state parameter, and microphysics flight-level data in netCDF format.

  • 2.0 (2017-05-03):

    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. TORERO 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.

    In this process, variables with 1DC in the name have been replaced with 2DC.
