Webthe Fraunhofer spectrum. In 1802, a scientist called W.H. Wollaston noticed that the visible spectrum from the Sun had several dark lines in it. Not long afterwards, Joseph von Fraunhofer built the first spectrometer. This focused sunlight from a small telescope onto a narrow slit. The light then passed through a prism, which produced the spectrum.

WebThis spectral window includes several solar Fraunhofer lines, together with the O 2-A and O 2-B absorption bands . Space-based Fs retrieval was first carried out by Guanter et al. in a small region in Spain using MERIS data from the O 2 -A absorption band [ 16 ].
