<h4 class="my-4 py-2 text-primary">Data Repository</h4>

Our web page offers an <a href="/WRI1030197">HTML-browsable version</a> of the data from the concentrating solar power plant in Jülich, Germany, with the global power plant id (GPPD) WRI1030197. A programmatic API is provided in our <a href="https://github.com/ARTIST-Association/PAINT">repository</a> as a PyTorch dataset and STAC client.

<h4 class="my-4 py-2 text-primary">Data Types</h4>

<dl class="row">
    <dt class="col-lg-2 col-12 text-primary">Calibration</dt>
    <dd class="col-lg-8 col-12">RGB photos of the focused sunlight spots of heliostats on dedicated calibration receivers.</dd>
    <dd class="col-lg-2 col-12">Format: <a href="https://www.w3.org/TR/2003/REC-PNG-20031110/">PNG</a></dd>

    <dt class="col-lg-2 col-12 text-primary">Deflectometry</dt>
    <dd class="col-lg-8 col-12">This measurement method allows the assessment of reflective surface properties. PAINT contains strip-pattern deflectometries of the power plant's heliostats, enabling identification of surface deformations.</dd>
    <dd class="col-lg-2 col-12">Format: <a href="https://docs.hdfgroup.org/hdf5/v1_14/_f_m_t3.html">HDF5</a></dd>

    <dt class="col-lg-2 col-12 text-primary">Kinematic</dt>
    <dd class="col-lg-8 col-12">Mechanical arrangement and angles of the heliostat motors.</dd>
    <dd class="col-lg-2 col-12">Format: <a href="https://www.json.org/json-en.html">JSON</a></dd>

    <dt class="col-lg-2 col-12 text-primary">Weather</dt>
    <dd class="col-lg-8 col-12">Medium-quality data from plant-local sensors and high-quality data from the DWD weather station in Aachen-Orsbach. Measured quantities include short- and long-wave radiation, global surface irradiance, sunshine duration, cloud cover, humidity, vapor pressure, and visibility range.</dd>
