Cirrus Cumulus Stratus Nimbus (CCSN) Database

The CCSN dataset contains 2543 cloud images. According to the World Meterological Organization’s genera-based classification recommendation, we divide into 11 different categories： Ac, Sc, Ns, Cu, Ci, Cc, Cb, As, Ct, Cs, St. It is worth noting that contrails have consideration in our dataset. Representative sample images from each category are shown below. Ci = cirrus; Cs = cirrostratus; Cc = cirrocumulus; Ac = altocumulus; As = altostratus; Cu = cumulus; Cb = cumulonimbus; Ns = nimbostratus; Sc = stratocumulus; St = stratus; Ct = contrail. All images are fixed resolution 256×256 pixels with the JPEG format.
