TL;DR: The surface-leaving radiance model developed in Part I is validated against an exhaustive set of Fourier transform spectrometer field observations acquired at sea, showing the model to have reduced bias over standard models at emission angles > or = 45 degrees.
Abstract: The surface-leaving radiance model developed in Part I [Appl. Opt.47,3701 (2008)] is validated against an exhaustive set of Fourier transform spectrometer field observations acquired at sea. Unlike prior limited studies, these data include varying all-sky atmospheric conditions (clear, cloudy, and dusty), with regional samples from the tropics, mid-latitudes, and high latitudes. Our analyses show the model to have reduced bias over standard models at emission angles ≳45°.

TL;DR: In considering this technique of spectroscopy, it is interesting and useful to begin with Michelson's "visibility curves"; briefly outlining the basis of Fourier Transform spectroscopic, and then to take a giant step in terms of time and technology.
Abstract: Fourier Transform spectroscopy is beginning to flourish. However, unlike the almost explosive growth following a discovery in some fields, such as gas chromatography or lasers, the use of scanning interferometer systems to measure spectra has had to pass through a long period of quiescence. The latter was, essentially, enforced through the lack of technology, and it was the emergence of electronics and computer science that made Fourier Transform spectroscopy feasible. Further advances in technology, especially the recent advent of the minicomputer, are now rapidly raising Fourier Transform spectroscopy from obscurity. The success story, then, goes back for three quarters of a century (or even further, if one thinks of Robert Boyle's observation in t663 of what are now termed \"Newton's Rings\" Et~ and Fizeau's use of interference to study the yellow sodium doublet ~2~). In considering this technique of spectroscopy, it is interesting and useful to begin with Michelson's \"visibility curves\"; briefly outlining the basis of Fourier Transform spectroscopy, and then to take a giant step in terms of time and technology.

TL;DR: Doppler-free high-resolution and high-frequency-accuracy broadband measurements were realized using the proposed OODR dual-comb spectroscopic technique, which does not require high-power-per-mode frequency combs.
Abstract: We present a Doppler-free high-resolution dual-comb spectroscopy technique in which a dual-comb system is employed to perform optical-optical double-resonance (OODR) spectroscopy In our experimental study, Doppler-free high-resolution and high-frequency-accuracy broadband measurements were realized using the proposed OODR dual-comb spectroscopic technique, which does not require high-power-per-mode frequency combs We observed fully resolved hyperfine spectra of 5P3/2 - 4D5/2, 4D3/2 transitions of Rb at 1530 nm and precisely determined the absolute frequencies of the transitions, with an uncertainty of less than 1 MHz The variations of the OODR spectral line shapes due to power broadening and alignment and the effects of polarization on the dual-comb OODR spectra were also analyzed This study provides a widely applicable technique for Doppler-free dual-comb spectroscopy of various gaseous species

TL;DR: In this paper, the first measurements of the optical spectra of NdFe 3 (BO 3 ) 4, a promising material for optoelectronics, were reported, and the temperature dependences of the exchange splitting and of the linewidth point to the temperature T c =33±1/k of the magnetic ordering in both iron and neodymium magnetic subsystems.
