PREDICT: 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 PRE-Depression Investigation of Cloud-systems in the Tropics (PREDICT) project. This dataset contains low rate navigation, state parameter, and microphysics flight-level data in netCDF format. NOTE: This dataset was updated Aug 4, 2011 to include production CVI data.

Additional information

Identifier	DOI: https://doi.org/10.5065/D61R6NV5
Data Quality	final
Versions	0.8 (2011-02-03) 0.9 (2011-04-15) 1.0 (2011-08-04) 2.0 (2019-01-25): This version 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. 3.0 (2021-08-06): Aerosol data (UHSAS and WCN) have been updated based on new QAQC procedures, and an error in the algorithm for processing the UHSAS sample flow has been corrected. *_OPC data have been removed. (Only the current version of the data is available to order. If you have questions about a prior version, please email us.)
