Satellite measurements of trace gases using blind source separation

We propose a new method for trace gases concentration using satellite measurements. The main idea is to use the full retrieved waveform through a blind source separation algorithm, instead of processing differential observation taken from a few absorption lines. The main assumption in this work is that the spectral waveforms from atmosphere contributions can be considered statistically independent. Results show that the algorithm is able to operate quite good although some unwanted features from clouds are clearly observed.
