molecular iodine photodestruction the coastal region around Roscoff
2010/12/28
Iodine emissions from the dominant six macroalgal species in the coastal regions around Roscoff, France, have been modelled to support the Reactive Halogens in the Marine Boundary Layer Experiment (RH...
Global fire emissions and the contribution of deforestation, savanna, forest, agricultural, and peat fires (1997–2009)
Global fire deforestation savanna forest agricultural peat fires
2010/12/28
New burned area datasets and top-down constraints from atmospheric concentration measurements of pyrogenic gases have decreased the large uncertainty in fire emissions estimates. However, significant ...

Atmospheric three-dimensional inverse modeling of regional industrial emissions and global oceanic uptake of carbon tetrachloride
regional industrial emissions global oceanic carbon tetrachloride
2010/11/29
Carbon tetrachloride (CCl4) has substantial stratospheric ozone depletion potential and its consumption is controlled under the Montreal Protocol and its amendments. We implement a Kalman filter using...
Evolution of gaseous disk viscosity driven by supernova explosion. II. Structure and emissions from star-forming galaxies at high redshift
gaseous disk viscosity driven supernova explosion
2011/1/10
(Abridged) High redshift galaxies are undergoing intensive evolution of dynamical structure and morphologies. We incorporate the feedback into the dynamical equations through mass dropout and angular ...
