Data are provided as the standard set of Cloudnet output files. All data files are netCDF, with one file per day. The data are organized as subsets in seven directories, each containing 77 nc files:
**classification** — Basic particle type classification for each time/height grid point (liquid, ice, aerosol...), cloud boundary altitudes.
**categorize** — The various input data and some derived quantities, used by cloudnet (radar reflectivity, lidar backscatter, profiles of temperature, humidity, wind, etc).
**lwc-adiabatic-method** — Cloud liquid water content derived from an assumption of adiabatic profiles, also liquid water path.
**lwc-scaled-adiabatic** — Cloud liquid water content derived from an assumption of adiabatic profiles scaled to the total liquid water path (derived from microwave radiometer retrieval), also liquid water path.
**iwc-Z-T-method** — Ice water content and total ice water path.
**drizzle** — Drizzle precipitation rate.
**lwf-Z-rainrate** — Liquid water precipitation rate, and droplet properties.
All files include time and position (latitude, longitude), and descriptions of the variables and methods and assumptions used to derive them. Retrieval uncertainties are given for most variables.
An additional directory contains png image files with various plots of the data.
Total file size: 17.7 GB.
