Short summary
A new cloud detection algorithm using the downwelling IR radiation has been developed by utilizing the spectral and temporal characteristics of clouds which significantly increase the measured radiance and temporal variability. Algorithm performance is evaluated by collocated ceilometer data showing the proportion of correct and probability of detection values of 88.3% and 90.8%, respectively. The algorithm is found to be insensitive to the presence of the inversion layer.
