Brazilian Atmospheric Inventories - BRAIN version 2: air quality dataset in Brazil - 2020

We coupled emissions inventories, the Weather Research and Forecasting (WRF) model, and the Community Multiscale Air Quality Modeling System (CMAQ) to produce the BRAIN air quality dataset for Brazil. CMAQ version 5.3.2 was set up using the third version of the Carbon Bond 6 chemical mechanism (cb6r3_ae7_aq) with AERO7 treatment of Secondary Organic Aerosol for standard cloud chemistry. Other model configurations used in this work can be found in SM5 and github.com/leohoinaski/CMAQrunner.

The pollutant list in CMAQ outputs containing multiple species.The CMAQ standard profile of boundary conditions is used in the larger domain (d01), which provides the boundary conditions for the smaller one (d02). The simulations have 24 hours length and time step interval of 1 hour. The last hour of the previous simulation has been set up as the initial condition of the next one.
