"This page presents an overview of the [Eye2Sky cloud camera network](https://www.dlr.de/en/ve/research-and-transfer/research-infrastructure/laboratories-infrastructures/eye2sky) in north-west Germany. Part of the dataset has been made [public on Zenodo](https://zenodo.org/records/12804613), and an example of how to retrieve data using Python is provided. See [Schmidt et al. (2022)](https://doi.org/10.1049/icp.2022.2778) for more information.\n",

"> \"In north-west Germany between Oldenburg, the North Sea coast and the Dutch border, the Institute of Networked Energy Systems operates the unique Eye2Sky cloud camera network as a research infrastructure. The network is growing dynamically and currently consists of around 30 stations. The heart of each station is a cloud camera, also known as an all-sky imager (ASI). This is a commercially available webcam with a fisheye lens supplemented by a ventilation and heating system that ensures optimum image quality even in bad weather. A third of the stations are equipped with a rotating shadowband irradiometer (RSI), other radiation sensors and meteorological sensors for temperature and humidity, for example, to validate and calibrate the algorithms.\"\n"
