DC3: High Rate (HRT - 25 sps) Navigation, State Parameter, and Microphysics Flight-Level Data (NetCDF) [NCAR/EOL]

Summary

This dataset contains airborne measurements collected aboard the NSF/NCAR GV HIAPER by the onboard Airborne Data System (ADS) during the Deep Convective Clouds and Chemistry Project (DC3) field campaign. These files contain HRT (25 samples per second) flight-level data, including navigation and state parameters, and selected scientific instrumentation fed to the ADS system during the flight. These are netcdf files.

Data Quality	final
Versions	1.0 (2012-10-01) 2.0 (2017-05-08): In this version the variables IRB and IRT were renamed to IRBV and IRTV to reflect the fact that the units are in volts. In addition, a new algorithm for calculating UHSAS flow has been applied to that data. (Only the current version of the data is available to order. If you have questions about a prior version, please email us.)
