BrO/SO2 molar ratios from scanning DOAS measurements in the NOVAC network
BrO/SO2 molar ratios scanning DOAS measurements NOVAC network
2015/1/6
The molar ratio of BrO to SO2 is, like other halogen/sulfur ratios, a possible precursor for dynamic changes in the shallow part of a volcanic system. While the predictive significance of the BrO/SO2 ...
A mechanistic modelling and data assimilation approach to estimate the carbon/chlorophyll and carbon/nitrogen ratios in a coupled hydrodynamical-biological model
mechanistic modelling data assimilation approach carbon/chlorophyll and carbon/nitrogen ratios
2009/11/11
The principal objective of hydrodynamical-biological models is to provide estimates of the main carbon fluxes such as total and export oceanic production. These models are nitrogen based, that is to s...
