Low Rate (LRT - 1 sps) Navigation, State Parameter, and Microphysics Flight-Level Data

Summary

This dataset includes airborne measurements obtained from the Gulfstream-V High-performance Instrumented Airborne Platform for Environmental Research (NSF/NCAR HIAPER) aircraft (Tail Number N677F) during the CONvective TRansport of Active Species in the Tropics (CONTRAST) project. This dataset contains low rate navigation, state parameter, and microphysics flight-level data in netCDF format.

As of March 3, 2016, this dataset contains updated Ultra High Sensitvity Aerosol Spectrometer (UHSAS) data that corrects underestimated ambient concentrations.

    This update contains corrected 2DC data (variable names ending in _LWOO). 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. However when a buffer spans multiple seconds, all 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. Finally, the variable A1DC, which was accidentally left in the last version, has been removed.

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