Image Comparison from two cloud cover sensor in infrared and visible spectral regions
Total Sky Imager (TSI) and Cloud Infrared Radiometer (CIR) are two instruments measuring cloud cover. TSI uses a CCD camera and produces images in the visible spectral range. CIR utilises seven infrared pyrometer sensors (9-14 microns). We will present a comparison of images obtained with the two instruments and an algorithm for further data analysis.
