VCSEL 25Hz Water Vapor Data https://data.eol.ucar.edu/dataset/552.052 Summary This data set contains 25 Hz water vapor mixing ratio data from the VCSEL (Vertical-Cavity Surface-Emitting Laser) hygrometer that was deployed on the NSR/NCAR GV HIAPER aircraft during the SOCRATES (Southern Ocean Clouds Radiation Aerosol Transport Experimental Study) field season. Identifiers * Local archive identifier: 552.052 * doi:10.26023/V925-2H41-SD0F https://doi.org/10.26023/V925-2H41-SD0F Versions 1.0 2.0: The main change is to apply a more strict QA/QC that filters out more problematic samples. The mixing ratio values have been rounded up to three significant digits. Citation Diao, M. 2021. VCSEL 25Hz Water Vapor Data. Version 2.0.
