Low Rate (LRT - 1 sps) Clouds data subset (ICARTT format) https://data.eol.ucar.edu/dataset/353.225 Summary This data set includes airborne measurements obtained from the NSF/NCAR HIAPER GV aircraft (Tail Number N677F) during the DC3 project. This dataset contains 2DC data (CONC2DC[AR]_LWOI, DBAR2DC[AR]_LWOI, and PLWC2DC[AR]_LWOI) extracted from updated netCDF data files. Files are in ICARTT format. EOL previously released 1D data for DC3 in ICARTT format. This data is slightly different from that data, so users who are focusing on cloud particle research may wish to download this data. Identifiers * Local archive identifier: 353.225 * doi:10.5065/D67943HP https://doi.org/10.5065/D67943HP Versions 3.0: This dataset contains 2DC data (CONC2DC[AR]_LWOI, DBAR2DC[AR]_LWOI, and PLWC2DC[AR]_LWOI) extracted from updated netCDF data files. It was discovered that all particles in a single buffer were 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. Citation UCAR/NCAR - Earth Observing Laboratory. 2018.
