Rødby - nearshore PM vertical profiles

<p>Vertical profiles up to 120 m of PM1, PM2.5 and PM10 using a multi-rotor uncrewed aerial system (UAS) and an optical particle counter (OPC). </p> <p><br></p> <p>Files named "baro" are exports of the UAS autopilot. baro_1 and baro_2 correspond to the first two flights, and baro_3-4 combines flights 3-4. From there, columns of importance are:</p> <p>timestamp: Datetime in epochtime [ns]</p> <p>Alt: Altitude [m]</p> <p>Press: Air pressure [Pa].</p> <p><br></p> <p>Four OPC output files are included stating the sensor used and the time of the measurements, with the following name convention: sensor_name_datetime</p> <p><br></p> <p>From the data file, the following columns are of importance:</p> <p>Date: Date and time of each measurement</p> <p>Bin0 - Bin23: OPC size channels</p> <p>SFR: Sampling flow rate [100 ml s-1]</p> <p>Sampling Period: The sampling time for each measurement [100 s]</p> <p>PM1, PM2.5, PM10: PM concentrations [μg m-3]</p>
