Air Quality Forecast Importance • In Mexico City Metropolitan Area (MCMA) the ozone levels have exceeded the standard (110 ppb) on 50% of the days in 2010. The programs to prevent the environmental con<ngencies are applied a`er the people have been exposed to high ozone levels. • An air quality forecast it is necessary in order to reduce exposure to ozone and other air pollutants
Dynamic DownscalingRegCM3 is a compressible, finite difference model with hydrostatic balance and vertical sigma-coordinates.Similar a MM5 pero adaptado para estudios climáticos. Domain 2 100.6W-97.3W y 17.8N-21N Grid of 140 x 140; ds=30km Domain 1 122W-86W y 16N-32N Grid of 160 x 80; ds=30km
Temperature (°C). Diﬀerence between reference climatology (1983-‐1990) and scenario (2071-‐2073).

Importance of HPC • Increased compu<ng power for atmospheric chemistry, weather and climate provided informa<on for decision makers, scien<sts and general public. • Forecast or climate predic<on need strong scaling: faster nodes and processors, not more of them. • The new genera<ons of mul<-‐ and many-‐core processors are an op<on. • Developments in so`ware area are required to use new technologies.
