Abstract 

 

All Sky Imagers or Total Sky Imagers (ASIs or TSIs) have substantial promise as scalable sensors for solar resource estimation and forecasting. ASI images are high-resolution fisheye images containing large amounts of sky content. This dataset contains ASI images taken at a 30-second time resolution, over a period of 17 days during April 2019 using an all-sky imager model ASI-16 by EKO Instrument. These images were used to test an automated clear sky image selection algorithm, however they can be used for a variety of other purposes including cloud position forecasting or solar irradiance estimation. 

Instructions: 

The dataset is stored as a tarball (.tar.gz). Data can be extracted on most Linux systems using the command `tar -xzvf ASIs.tar.gz`. On MacOS systems the Archive Utility should be able to extract .tar.gz files by default. On Windows systems third-party software such as 7zip is available to extract tarballs. Alternatively the Windows Linux Subsystem can be used with the command `tar -xzvf ASIs.tar.gz`.
