The Whole Sky Imager (WSI) is an automated ground-based system used to assess and document cloud fields and cloud fields dynamics. A basic WSI consists of an optical clear dome, camera body with fish eye lens and a single-board computer to control the camera. The WSI will be operated in harsh environment. Special care has to be taken when designing the new WSI to ensure the system is kept cool and dry to protect the components. The size of the new WSI is an important factor to consider as the WSI will be deployed in other sites other than in the university. The images captured by the camera through the optical clear dome must be sharp so that the images can be used for cloud monitoring to study how clouds can attenuate signals.
