<p>Data and script for "Fireworks and ruffled feathers: L-band radar quantifies major disturbance of urban birds" submission to Biology Letters</p> <p><br></p> <p>Data Description:</p> <p><br></p> <p>Data files contained in the "Tracks" folder of the "BL_UrbanFireworks" top folder consist of track values obtained </p> <p>from an L-band staring radar positioned near the city of Birmingham, UK. For the track files without the "Mode_sum" </p> <p>in the title, each line gives information for a single detection point. Multiple points then make up a single track</p> <p>(e.g., there are 699 detections for the track "TP-2021-09-29-08-11-17_2021_10_03_240000799_ID11408612"). The variables</p> <p>are detailed below:</p> <p>- "steps": The number of detections making up the unique track</p> <p>- "ID": The unique track identifier</p> <p>- "speed": The aerial velocity (m/s) of the track at that detection point</p> <p>- "designation": The designation given by the radars onboard classification</p> <p>- "AG.m.": The above ground height (m) of the detection</p> <p>- "Combined.Time": Not used</p> <p>- "Second": The second of the time of detection</p> <p>- "Minute": The minute of the time of detection</p> <p>- "Hour": The hour of the time of detection</p> <p>- "Day": The day of month at the time of detection</p> <p>- "Month": The month of the time of detection</p> <p>- "Year": The year of the time of detection</p> <p><br></p> <p>All track files with "Mode_sum" within the title are made up of: </p> <p>- "Mspeed": The mean aerial velocity (m/s) of the track across detections</p> <p>- "des": The designation given by the radars onboard classification across the detections (mode)</p> <p>- "steps": The number of detections making up the unique track</p> <p>- "ID": The unique track identifier</p> <p>- "AG.m.Min": The minimum above ground height (m) for the track</p> <p>- "AG.m.Max": The maximum above ground height (m) for the track</p> <p>- "AG.m.M": The mean above ground height (m) for the track</p> <p>- "Time_start": The time of the first detection in the track. In the format "HHMMSSPPP", where P donotes milliseconds.</p> <p>- "Time_end": The time of the last detection in the track. In the format "HHMMSSPPP", where P donotes milliseconds.</p> <p>- "Day": The day of month at the time of detection</p> <p>- "Month": The month of the time of detection</p> <p>- "Year": The year of the time of detection</p> <p><br></p> <p>The R script, "FireworksMS_script", can be used to repeat the analyses and produce the figures within the manuscript.</p> <p>To utilise the script, ensure all packages including at the top of the script are installed. Change the "setwd()" command</p> <p>to the location of the folder (this will change automatically should you load the script from the folder). </p> <p>The function, "rolling10plots_v02.R", is used to produce the 1 minute rolling plots.</p>
