ARL-Developed Data Tools & Products for Surface Atmosphere Exchange

NACC Cloud

NACC Cloud couples National Weather Model GFSv16 data to a state-of-the-science CMAQ model for regional air quality modeling applications. NACC Cloud offers streamlined access to the near-real-time GFS forecasts NACC processed to generate the model-ready, meteorological input for any U.S. EPA Community Multiscale Air Quality (CMAQ ) domain and air quality application worldwide.

Canopy-App 

Canopy-App models complex in-canopy effects in regional-to-global weather and atmospheric composition applications under the UFS, building on established canopy parameterizations. Canopy-App uses relatively simple plant shape distribution functions for different vegetation types and computes select variables and adjustment factors used for efficiently modulating atmospheric quantities (such as gas-phase chemical species) due to vertically resolved canopy effects.

The NOAA Emission and Exchange Unified System (NEXUS)

Emissions are a central component of atmospheric chemistry models. The NOAA Emissions and eXchange Unified System (NEXUS) at ARL is an application of the Harmonized Emissions Component (HEMCO) into the NOAA’s Unified Forecast System (UFS) architecture. HEMCO is a software component for computing emissions from a user-selected ensemble of emission inventories and algorithms. It allows users to re-grid, combine, overwrite, subset, and scale emissions from different inventories through a configuration file and with no change to the model source code.
