Eye2Sky dataset - All-sky images and meteorological measurements

Kurzfassung

The Eye2Sky public dataset comprises all-sky images from 29 All-Sky Imager (ASI) stations and meteorological measurements including solar irradiance from 11 stations in north-west Germany. A list of all stations with meta information is provided. Meteorological measurements cover a full year from April 2022 to March 2023 with minutely averaged parameters. Parameters measured are three solar radiation components global horizontal, diffuse horizontal and direct normal irradiance. Global tilted irradiance is measured with tilt angles of 30° in southern direction. Measurement data has been quality controlled. Raw data is provided along with quality flags. For users who want to use measurements directly, a "ready-to-use" data set with cleaned data is provided. ASI images of the whole ASI network at all stations cover a 4-month period from April to July 2022 with 30 seconds sampling rate, for station OLUOL the dataset covers a full year from April 2022 to March 2023 to allow season-dependent analyses at a central location inside the ASI network. The sampling rate for OLUOL is 15 seconds (since 2022-06-10). Images are provided as raw data (jpg-format), but calibration information and horizon masks are provided as meta data. Note: Due to maximum upload size allowed by Zenodo, only an example data set is provided here. The full set of ASI images can be downloaded from here: https://eye2sky.de/data
