SICAH: an automatic system for the control and prevention of air pollution in Huelva (Spain)
An automatic system for control of the air pollution in the industrialised area of Huelva has being developed by CIEMAT. This system is called "Sistema informatico para control y prevencion de la contaminacion atmosferica en Huelva" (SICAH). SICAH is a Visual C++ programme that runs under Windows 95/NT. SICAH includes a Geographic Information System (GIS) and runs Fortran numerical scientific codes including a mesoscale Lagrangian puff dispersion model called MELPUFF. SICAH has been designed to receive and automatically process the information on air quality, emission and meteorological networks in real-time and provide predictions of concentrations of SO2, PM10, SH2 and CO.
