This paper presents the intrinsic fluorescence characteristics of vitamin B1, B2 and B6 measured with 3D fluorescence Spectrophotometer. Three strong fluorescence areas of vitamin B2 locate at λex/λem=270/525nm, 370/525nm and 450/525nm, one fluorescence areas of vitamin B1 locates at λex/λem=370/460nm, two fluorescence areas of vitamin B6 locates at λex/λem=250/370nm and 325/370nm were found. The influence of pH of solution to the fluorescence profile was also discussed. Using the PARAFAC algorithm, 10 vitamin B1, B2 and B6 mixed solutions were successfully decomposed, and the emission profiles, excitation profiles, central wavelengths and the concentration of the three components were retrieved precisely through about 5 iteration times.
The Tibet plateau is characterized with its own special highland climate environment. In this paper, the temporal vertical profiles of aerosol extinction/backscattering coefficients, the boundary layer height (BLH) and cloud height during the CAMP-Tibet 2003 autumn and 2004 spring session observations at Naqu BJ site, Tibet are determined with ancillary meteorological parameters, and compared with data at Bejing site.
MODIS a moderate-resolution imaging spectroradiometer instrument on board EOS-AM1 and PM1 has 36 spectral bands amongst which only 9.6 μm band sensitively traces atmospheric ozone. To produce total ozone inversion one requirement is via temperature and pressure profiles a popular requirement of mass-calculation which could now be argued not a literally convenient idea. Thus in this paper I try my hand at a new method through firstly overall bands' correlative statistics and analysis based on MODIS high-precision data source in spectral radiation to materialize "similar TRIPLET" spectral data combination method. Then it comes to us a need to attain a solid cooperative optimization and thirdly with forgoing output a process is introduced here of spectrum differential calculation leading to final total ozone inversion.
