This Dataset includes 2002-2011 daily average air quality concentrations of multiple species (fine and coarse mode aerosol sulfate, nitrate, calcium, potassium, and sodium; benzene; CO; H2O2; OH; SO2) for Barbados estimated from the Community Multiscale Air Quality (CMAQ) model as part of the EPA's Air Quality Time Series (EQUATES) Project. CMAQ estimates were from simulations of the Northern Hemisphere with horizontal grid spacing of 108 km x 108 km. Model estimates were extracted from the lowest CMAQ model layer (∼ 10 m in thickness) for a source area over the Atlantic Ocean to the east of the island from 14.3989 to 11.45667° N latitude and 59.5627 to 56.54487° W longitude (equivalent to 16 model grid cells with 1 cell over Ragged Point and the others to the east of the site). Modeled meteorological estimates (surface temperature, relative humidity, wind direction, wind speed) for the same set of grid cells was also extracted from simulations of the Weather and Research Forecasting (WRF) meteorological model used in the EQUATES project. Data for each model variable are provided as text files (one file for each variable and year) including date, grid cell center longitude and latitude, grid cell elevation and the the daily average model concentrations. Text files are compressed into .zip files for each variable. This dataset is associated with the following publication: Gaston, C., J. Prospero, K. Foley, H. Pye, L. Custals, E. Blades, P. Sealy, and J. Christie. Diverging trends in aerosol sulfate and nitrate measured in the remote North Atlantic on Barbados are attributed to clean air policies, African smoke, and anthropogenic emissions.

The Community Multiscale Air Quality (CMAQ) model version 5.4 (epa.gov/cmaq) was applied with 12 km sized grid cells for a domain covering the conterminous U.S. and areas offshore. The vertical atmosphere was resolved up to 50 mb with 35 layers. Vertical layers were thinner nearest the surface to best resolve diurnal fluctuation in the surface mixing layers. Lateral boundary inflow was extracted from a hemispheric scale simulation for the same year. Meteorological inputs were developed with the Weather Research and Forecasting model version 3.8.1 applied with the same grid domain as the photochemical model. The Pattern Constructed Air Pollution Surfaces (PCAPS) model has been applied for complex sector-specific emissions scenarios for stationary and mobile sources and predicted air quality results consistent with more sophisticated models. PCAPS version 1.1 was applied for each year between 2024 and 2031 with year-specific offshore wind project and EGU emissions. PCAPS was also applied using the same offshore wind and onshore EGU emissions for the 2026 and 2055 scenarios simulated with CMAQ to allow for a direct comparison of results.
