Level 0 is raw data in csv format, other levels require https://github.com/JGirdwood/AeroSAM-Analysis to process. Each file is data from a separate take-off. Each file is named with the following convention (delimited with _): UAVName_UCASSName_Date_TakeOffTime_Iteration. Directory: 20-09-29 Description: FMI-Talon -- UCASS data collected on the 29th of September 2020. Level 0 is raw data in csv format, other levels require https://github.com/JGirdwood/AeroSAM-Analysis to process. Each file is data from a separate take-off. Each file is named with the following convention (delimited with _): UAVName_UCASSName_Date_TakeOffTime_Iteration. Directory: FMI_FD Description: Flight data from the FMI-talon. These are pixhawk 2.1 logs which can be read with the MAVLINK protocol. Each file is data from a separate take-off. Each file is named with the following convention (delimited with _): UAVName_Date_TakeOffTime_Iteration. These files are not in columnated format and will need to be read using the mavlink open source software: https://github.com/mavlink/mavlink Directory: FMI_METD Description: Meteorological data from the FMI-Talon. These are csv files which contain temperature, pressure, and humidity. Each file is data from a separate take-off. Each file is named with the following convention (delimited with _): SensorName_UAVName_Date_TakeOffTime_Iteration. The columns in each file are: Date, Time, Temperature (c), pressure (hPa), Relative Humidity (%) Directory: SAMMAL_METD Description: Meteorological data from Sammaltunturi station. Each file is data on a different date. Each file is named with the following convention (delimited with _): Sammal_Instrument_Date. The columns in each file are: Read time (UTC+2), Temp 570m (C), Room temp (C), Dew point temp (C), Humidity 570m (%), Pressure (hPa), Wind speed (m/s), Wind dir (deg), Sun rad 1 (W/m2), Sun rad 2 (umol/s/m2), FD12P visibility (m), Precipitation type (code), Rain intensity (mm/h), Error code 1 (code), Error code 2 (code), Temp 545m (C) Directory: UCASS_LUT Description: Lookup tables for the UCASS units used, created before and after the campaign. Each file is named with the following convention (delimited with _): UCASSName_GainMode_Material_Date. The columns in each file are: 12-bit output, particle diameter (um) File: ActiveUCASS.txt Description: List of Active UCASS units and metadata. The columns are: Serial number, Gain mode, Location -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: These data were collected during the Pallas Cloud Experiment (PaCE) campaign in northern Finland in 2020. The campaign involved measurements by The FMI-Talon Fixed Wing UAV, and static measurements at a research station. The UAV was flown through stratus cloud and data from its on-board sensors were collected and logged. 2. Methods for processing the data: The data published here are the raw data from the campaign, the Airborne Particle Analysis software (https://github.com/JGirdwood/AeroSAM-Analysis) allows easy automatic data quality assurance criteria to be set. 3. Instrument- or software-specific information needed to interpret the data: The primary data used here are from the UCASS instrument (described in https://doi.org/10.5194/amt-12-6579-2019, 2019). The Airborne Particle Analysis software (https://github.com/JGirdwood/AeroSAM-Analysis) is recommended as a processing tool, but not essential. 4. Environmental/experimental conditions: Pallas Cloud Experiment 2020 in subarctic Finland 5. Describe any quality-assurance procedures performed on the data: The data published here are the raw data from the campaign with no quality assurance, QA can be performed automatically by the Airborne Particle Analysis software (https://github.com/JGirdwood/AeroSAM-Analysis). ----------------------------------------------- DATA-SPECIFIC INFORMATION FOR: 20-09-28/level_0 ----------------------------------------------- This is a directory, the following is applicable for every file in the directory 1.
