An integrated model of soil-canopy spectral radiances, photosynthesis, fluorescence, temperature and energy balance
soil-canopy spectral radiances photosynthesis fluorescence temperature energy balance
2010/1/21
This paper presents the model SCOPE (Soil Canopy Observation, Photochemistry and Energy fluxes), which is a vertical (1-D) integrated radiative transfer and energy balance model. The model links visib...
A systematic study on the absorption and fluorescence properties of 2,4,6-triaryl and tripyridylpyridines
2,4,6-triarylpridine 2,4,6-tripyridylpridine fluorescence UV-Vis absorption fluorescence quantum yield fluorescence lifetime
2010/4/8
Eight different 2,4,6-triaryl, and tripyridylpridines compounds were synthesized and their fluorescent properties were studied by using steady-state and time-resolved fluorescence and UV-Vis absorptio...
A flow-tube based laser-induced fluorescence instrument to measure OH reactivity in the troposphere

2010/2/8
A field instrument utilising the artificial generation of OH radicals in a sliding injector flow-tube reactor with detection by laser-induced fluorescence spectroscopy has been developed to measure th...
Twin image removal in X-ray fluorescence holography with two energies
X-ray holography twin image
2009/8/13
In the last decade, X-ray fluorescence holography has been developed for the study of 3D atomic arrangements in solids. However, it encounters the twin image problem which may disturb the reconstructe...

Satellite-detected fluorescence reveals global physiology of ocean phytoplankton
Satellite-detected fluorescence global physiology ocean phytoplankton
2010/1/20
Phytoplankton photosynthesis links global ocean biology and climate-driven fluctuations in the physical environment. These interactions are largely expressed through changes in phytoplankton physiolog...
Intensity-field correlation of single-atom resonance fluorescence
Intensity-field single-atom resonance fluorescence
2010/4/9
We report measurements of an intensity-field correlation function of the resonance fluorescence of a single trapped Ba+ ion. Detection of a photon prepares the atom in its ground state and we observe ...
Measurements of OH and HO2 concentrations during the MCMA-2006 field campaign – Part 1: Deployment of the Indiana University laser-induced fluorescence instrument
OH HO2 MCMA-2006 field campaign laser-induced fluorescence instrument
2009/3/13
Measurements of tropospheric hydroxyl (OH) and hydroperoxy (HO2) radicals were made during the MCMA (Mexico City Metropolitan Area) field campaign as part of the MILAGRO (Megacity Initiative: Local an...
Intercomparison of peroxy radical measurements obtained at atmospheric conditions by laser-induced fluorescence and electron spin resonance spectroscopy
peroxy radical measurements atmospheric conditions laser-induced fluorescence electron spin resonance spectroscopy
2010/2/8
Measurements of hydroperoxy radical (HO2) and organic peroxy radical (RO2) concentrations were performed by two different techniques in the atmospheric simulation chamber SAPHIR in Jülich, Germany. Th...
Validation of the calibration of a laser-induced fluorescence instrument for the measurement of OH radicals in the atmosphere
laser-induced fluorescence instrument OH radicals atmosphere
2009/2/24
An assessment of the accuracy of OH concentrations measured in a smog chamber by a calibrated laser-induced fluorescence (LIF) instrument has been made, in the course of 9 experiments performed to stu...
Measuring atmospheric naphthalene with laser-induced fluorescence
atmospheric naphthalene laser-induced fluorescence
2009/2/24
A new method for measuring gas-phase naphthalene in the atmosphere is based on laser-induced fluorescence at low pressure. The fluorescence spectrum of naphthalene near 308 nm was identified. Naphthal...
Fluorescence from atmospheric aerosol detected by a lidar indicates biogenic particles in the lowermost stratosphere
Fluorescence atmospheric aerosol biogenic particles lowermost stratosphere
2009/2/6
With a lidar system that was installed in Lindenberg/Germany, we observed in June 2003 an extended aerosol layer at 13km altitude in the lowermost stratosphere. This layer created an inelastic backsca...
