title: Vertical profiles time series of bird density and flight speed vector (01.01.2018-01.01.2019).

description: <strong>Description</strong> This dataset contains the vertical profiles and integrated time series of bird density and flight speed (NS and EW) generated and used in Nussbaumer (2020). Data are stored in a JavaScript Object Notation (JSON) file for each radar, with the following structure: <pre><code class="language-javascript">{ "name" : "bejab", // Code name of the radar (http://eumetnet.eu/wp-content/themes/aeron-child/observations-programme/current-activities/opera/database/OPERA_Database/index.html) "lat" : 51.1917, // Latitude "lon" : 3.0642, // Longitude "height" : 50, // Elevation of the radar antenna [m] a.s.l. "heightDEM" : 0, // Elevation of the ground [m] a.s.l. "dens" : [[...],...], // Bird density [birds/km3] "sd_vvp" : [[...],...], // Radial velocity standard deviation "densSIMmean" : [[...],...], // Average bird density over 30 simulation over first elevation bins. (see [reference] for more details). [birds/km3] "bird" : [[...],...], // Bird proportion (0-1)(see [reference] for more details) [-] "insect" : [[...],...], // Insect proportion (0-1) (see [reference] for more details) [-] "ub" : [[...],...], // Bird flight speed in East(+)/West(-) [m/s] "vb" : [[...],...], // Bird flight speed in North(+)/South(-) [m/s] "ui" : [[...],...], // Insect flight speed in East(+)/West(-) [m/s] "vi" : [[...],...], // Insect flight speed in North(+)/South(-) [m/s] "uw" : [[...],...], // Wind speed in East(+)/West(-) [m/s] "vw" : [[...],...], // Wind speed in North(+)/South(-) [m/s] "volDir" : [[...],...], //Normalised volume of air available for flight [m] (see [reference] for more details) "denss" : [...], // Vertically Integrated bird density [birds/km2] "ubs" : [...], // Vertically Integrated bird flight speed in East(+)/West(-) [m/s] "vbs" : [...], // Vertically Integrated bird flight speed in North(+)/South(-) [m/s] }</code></pre> Two dimensional dataset (array of arrays) are given as <code>time</code> x <code>elevation</code> (25x45592) where time is provided as another JSON file included in the archive and elevation bins are centred at <code>[100, 300, 500 , ... , 4900]</code>. Note that the data are rounded at the second decimal place. <strong>Procedure</strong> See Supplementary Material 1 of Nussbaumer (2020) and rafnuss-postdoc.github.io/BMM/2018. <strong>Visualization</strong> bmm.raphaelnussbaumer.com/2018 bmm.raphaelnussbaumer.com/explorevp
