Picarro L2130-i Water Vapor and Ice Crystal Isotope Ratios https://data.eol.ucar.edu/dataset/594.001 Summary Water vapor and ice crystal isotope ratios were measured with two Picarro L2130-i water vapor isotopic analyzers: Desert Research Institute’s (DRI’s) HIDS2034 and NCAR’s HIDS2346. Both analyzers were operated at nominal 0.5 Hz frequency during the SPL deployment. HIDS2346 was operated in 5-Hz flight-ready mode during the instrument characterization, which took place December 20, 2018 – January 7, 2019. The download is organized as a single .tar.gz file that contains contains datafiles, datasets, and numerical processing scripts associated with the January 2019 Mixed Phase (cloud) Isotopes sampling experiment at Storm Peak Laboratory (SPL) in Steamboat Springs, Colorado. Specifically, the directory contains: • All uncorrected, sample rate data • Calibration data points • Models for correcting the data for known biases • Processing scripts for correcting, selecting, and averaging the data • Corrected data for the pre-deployment, main experiment, and post-experiment periods • “Quick look” visualization plots (Please see supporting documents ReadMe.pdf and MetaData_SPL_PreDeployment.pdf for additional dataset information.)
