Atmospheric corrections and interpretation of marine radiances in czcs imagery, revisited ArchiMer
Andre, Jm; Morel, A.
In a previous study (Bricaud and Morel, Oceanologica Acta, 1987), a reflectance model developed for oceanic Case 1 waters was introduced into CZCS data processing, mainly with the aim of improving the atmospheric correction scheme and permitting discrimination between Case 1 and turbid Case 2 waters. The present paper, not limited to CZCS, examines the possible extension of the use of this reflectance model. In particular, it is proposed that the relationships required in iterative computations when estimating marine radiances in the four (visible) channels be those which derive from the model rather than the empirical expressions. Also, in order to ensure an internal coherency, it is proposed to operate the modelled relationships between the reflectance...

Dynamics of ammonia exchange with cut grassland: strategy and implementation of the GRAMINAE Integrated Experiment Inra
Sutton, M.A.; Nemitz, E.; Theobald, M.R.; Milford, C.; Dorsey, J.R.; Gallagher, M.W.; Hensen, A.; Jongejan, P.A.C.; Erisman, J.W.; Mattsson, M.; Schjoerring, J.K.; Cellier, P.; Loubet, B.; Roche, R.; Neftel, A.; Hermann, B.; Jones, S.K.; Lehman, B.E.; Horvath, L.; Weidinger, T.; Rajkai, K.; Burkhardt, J.; Löpmeier, F.J.; Daemmgen, U..
A major international experiment on ammonia (NH3) biosphere-atmosphere exchange was conducted over intensively managed grassland at Braunschweig, Germany. The experimental strategy was developed to allow an integrated analysis of different features of NH3 exchange including: a) quantification of nearby emissions and advection effects, b) estimation of net NH3 fluxes with the canopy by a range of micrometeorological measurements, c) analysis of the sources and sinks of NH3 within the plant canopy, including soils and bioassay measurements, d) comparison of the effects of grassland management options on NH3 fluxes and e) assessment of the interactions of NH3 fluxes with aerosol exchange processes. Additional technical objectives included the inter-comparison...

Entradas atmosféricas-relaçoes de funcionalidade entre a precipitaçao e a composiçao quimica IRD
De Carvalho, C.N.; Leprun, Jean-Claude.
Ce travail présente une quantification des relations existantes entre les entrées atmosphériques analysées à partir de la collecte de la précipitation totale et la hauteur de précipitation dans la région de Rio de Janeiro (Brésil). Le comportement du sodium, du potassium, du calcium et du magnésium en fonction de la hauteur de pluie a permis de mettre en évidence des relations exponentielles décroissantes semblables entre la précipitation et la concentration des quatre éléments mesurés. L'élaboration d'un "modèle linéaire inverse" a permis de séparer par analyse de régression la composante chimique due à la pluie s.s. (celle du nuage) de celle due aux autres éléments, particules ou aérosols des impuretés présentes dans l'atmosphère. (Résumé d'auteur)

Heterogeneous ice nucleation activity of bacteria : new laboratory experiments at simulated cloud conditions Inra
Möhler, O.; Georgakopoulos, D.G.; Morris, C.E.; Benz, S.; Ebert, V.; Hunsmann, S.; Saathoff, H.; Schnaiter, M.; Wagner, R..
The ice nucleation activities of five different Pseudomonas syringae, Pseudomonas viridiflava and Erwinia herbicola bacterial species and of Snomax™ were investigated in the temperature range between −5 and −15°C. Water suspensions of these bacteria were directly sprayed into the cloud chamber of the AIDA facility of Forschungszentrum Karlsruhe at a temperature of −5.7°C. At this temperature, about 1% of the Snomax™ cells induced immersion freezing of the spray droplets before the droplets evaporated in the cloud chamber. The living cells didn't induce any detectable immersion freezing in the spray droplets at −5.7°C. After evaporation of the spray droplets the bacterial cells remained as aerosol particles in the cloud chamber and were exposed to typical...
