Meteorology, climate, emissions, atmospheric
chemistry, and air-quality represent the general defining areas for
research and modeling work at Altostratus. While scales of interest range from
the global to the local, the focus of modeling work at Altostratus is on the meso and meso-urban
(sub-meso) scales. Meteorological, emissions,
dispersion, and photochemical modeling is performed with state-of-science models
such as MM5, WRF, CAMx, CMAQ, and UAM-V, updated
anthropogenic and biogenic emission models and EMS-95/SMOKE, and Altostratus's URMICLEM and
Bee-Eye (BI) models, as well as new fine-resolution meso-urban meteorological models such as the uMM5
(Altostratus's modified version of the EPA UCP MM5). These tools and models are constantly
updated, improved, and adapted
to project-specific needs and applications. In addition, a new generation
of models and modeling techniques are currently being developed and tested,
including "urbanized", fine-resolution models.
Computing at Altostratus is
performed on fast Linux-based 64-bit machines with several configurations (single and
multi-processor platforms). |
