We consider a class of degenerate reaction-diffusion systems with quadratic nonlin-earity and diffusion only in the vertical direction. Such systems can appear in the modeling of photochemical generation and atmospheric dispersion of pollutants. The diffusion coefficients are different for all equations. We study global existence of solutions. Nous considérons une classe de systèmes dégénérés de réaction-diffusion avec une non-linarite ́ quadratique et avec diffusion uniquement dans la direction verticale. De tels systèmes peuvent apparâıtre dans la modélisation de la synthèse de polluants par réactions photochimiques et de leur dispersion atmosphérique. Les coefficients de diffusion sont différents pour chaque équation. Nous...
