A coupling procedure of air-sea freshwater exchange in climate system models is reported in this note. The first stage of the procedure is to force OGCM to equilibrium under strong restoring surface condition on salin...
THE production of C02 in the soil results from the oxidation of soil organic matter by heterotrophic microorganisms and by the respiration of plant roots. The release of C02 from the soil is a ma...
An equation used to calculate electromagnetic pressure for confining and shaping a plate-form melt with small or medium thickness is brought forward. The equation gives a precise relationship between electromagnetic p...
AGRICULTURAL soils are the major anthropogenic source of N2O, and temperature is one of the importantenvironmental factors controlling production and emission of N2O from soil. This work focuses ...
