    <dct:description>&lt;p&gt;The PV-Live dataset comprises data from a network of 40 solar irradiance measurement stations across the German state of Baden-W&amp;uuml;rttemberg. All stations measure global horizontal irradiance and temperature with a pyranometer, and global tilted irradiance in east, south, and west direction with tilt angles of 25&amp;deg; with three photovoltaic reference cells in minute resolution. A quality control&amp;nbsp;scheme has been developed specifically for this dataset and is applied to the measurements before publication. The minute resolution irradiance and temperature measurements are published with the derived quality flags. A short description of the dataset and the quality control scheme is given in Lorenz et al. (2020).&lt;/p&gt; &lt;p&gt;The dataset contains data from September 2020 onwards. It will be continuously&amp;nbsp;extended by adding data of the previous month on a monthly basis.&lt;/p&gt; &lt;p&gt;&amp;nbsp;&lt;/p&gt; &lt;p&gt;QUALITY FLAGS&lt;/p&gt; &lt;p&gt;Two types of flags are provided with the data. Each sensor is assigned a general quality flag, which is based on a combination of different tests. In addition, a shading flag is given, which is not sensor specific, i.e. it applies to all irradiance sensors simultaneously. The flags can have the levels &amp;#39;passed, all tests complete&amp;#39;, &amp;#39;passed, not all tests complete&amp;#39;, &amp;#39;failed tests, likely erroneous&amp;#39; or &amp;#39;failed tests, most likely erroneous&amp;#39;. If the flag level of the general quality flags is &amp;#39;failed tests, most likely erroneous&amp;#39; the corresponding measurement value is set to NaN.&lt;/p&gt; &lt;p&gt;&amp;nbsp;&lt;/p&gt; &lt;p&gt;DATA FORMAT&lt;/p&gt; &lt;p&gt;The data is published as monthly .zip archives. Each archive contains the following files:&lt;/p&gt; &lt;p&gt;1. Tab separated data files (tng000XX_YYYY-MM.tsv) for each station, containing measurements and quality flags of one month&lt;/p&gt; &lt;p&gt;2. Tab separated station location metadata (metadata_stations.tsv)&lt;/p&gt; &lt;p&gt;3. Metadata of the dataset describing variable names and quality flag levels (metadata_measurements.json)&lt;/p&gt; &lt;p&gt;4. General comments on data availability and quality for the month (comments_quality_control_YYYY-MM.txt)&lt;/p&gt; &lt;p&gt;&amp;nbsp;&lt;/p&gt; &lt;p&gt;ACKNOWLEDGEMENTS&lt;/p&gt; &lt;p&gt;The data have been collected and processed by Fraunhofer ISE in the framework of PV-Live, a project in cooperation with TransnetBW.&lt;/p&gt; &lt;p&gt;We thank our station partners for cooperation in installing and maintaining our measurement stations: EnBW Solar, Badenova, Pohlen Solar, Oekogeno Solar7, Ecovision, Hochschule Ulm, Hofgemeinschaft Heggelbach, Soltechnics-solution and the Stadtwerke Karlsruhe, Gr&amp;uuml;nstadt, Buchen, Crailsheim, Schw&amp;auml;bisch Hall, Pforzheim, Konstanz, Waldshut-Tiengen, Schw&amp;auml;bisch Gm&amp;uuml;nd, Ravensburg, Eberbach, Baden-Baden.&lt;/p&gt; &lt;p&gt;&amp;nbsp;&lt;/p&gt;</dct:description>
