  "abstract": "<p>The PV-Live dataset comprises data from a network of 40 solar irradiance measurement stations across the German state of Baden-W&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&deg; with three photovoltaic reference cells in minute resolution. A quality control&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).</p>\n\n<p>The dataset contains data from September 2020 onwards. It will be continuously&nbsp;extended by adding data of the previous month on a monthly basis.</p>\n\n<p>&nbsp;</p>\n\n<p>QUALITY FLAGS</p>\n\n<p>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 &#39;passed, all tests complete&#39;, &#39;passed, not all tests complete&#39;, &#39;failed tests, likely erroneous&#39; or &#39;failed tests, most likely erroneous&#39;. If the flag level of the general quality flags is &#39;failed tests, most likely erroneous&#39; the corresponding measurement value is set to NaN.</p>\n\n<p>&nbsp;</p>\n\n<p>DATA FORMAT</p>\n\n<p>The data is published as monthly .zip archives. Each archive contains the following files:</p>\n\n<p>1. Tab separated data files (tng000XX_YYYY-MM.tsv) for each station, containing measurements and quality flags of one month</p>\n\n<p>2. Tab separated station location metadata (metadata_stations.tsv)</p>\n\n<p>3. Metadata of the dataset describing variable names and quality flag levels (metadata_measurements.json)</p>\n\n<p>4. General comments on data availability and quality for the month (comments_quality_control_YYYY-MM.txt)</p>\n\n<p>&nbsp;</p>\n\n<p>ACKNOWLEDGEMENTS</p>\n\n<p>The data have been collected and processed by Fraunhofer ISE in the framework of PV-Live, a project in cooperation with TransnetBW.</p>\n\n<p>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&uuml;nstadt, Buchen, Crailsheim, Schw&auml;bisch Hall, Pforzheim, Konstanz, Waldshut-Tiengen, Schw&auml;bisch Gm&uuml;nd, Ravensburg, Eberbach, Baden-Baden.</p>\n\n<p>&nbsp;</p>",
