New DevelopmentsNew DevelopmentsMC2 to MM5 converterMC2 to MM5 converter
Convert MC2 output for input to SMOKE & CMAQ Re-project and interpolate horizontal grids Convert vertical grid to MM5 sigma levels Map different parameters between MC2 and MM5
Parallel processor CMAQ runs on LINUXParallel processor CMAQ runs on LINUX Compile CMAQ (source + libraries) to run in parallel
distributed LINUX environment (with UC Riverside)
Real-time AQ forecasting (MC2, SMOKE, CMAQ)Real-time AQ forecasting (MC2, SMOKE, CMAQ) Assist University of B.C. staff to setup of real-time
