Datasets PM2.5 simulated using WRF-Chem model

Data Statement

Number of vehicles dateset in Lima were obtained from a report by the Instituto Nacional de Estadistica e Informatica (INEI; translated as “National Institute of Statistics and Informatics”).

The vertical variation of potential (θ), equivalent potential (θe), and virtual (θV) temperatures, the atmospheric soundings dataset at the Jorge Chavez airport (JCAi; location: 12° S, 77°11' W; altitude: 13 MASL) in Lima were obtained from University Wyomin website: http://weather.uwyo.edu/upperair/sounding.html. The maximum (Tmax), minimum (Tmin) air temperature dataset measured at the Jorge Chavez airport (JCAi) in Lima were obtained from the Iowa State University website:

Spatial-temporal simulations of hourly measurements of air pollutants and meteorological variables dataset were carried out, for both vehicular emission gasses and aerosols in the WRF-Chem (version 4.0) model in Lima, which was used as the simulation control case.

Spatial-temporal simulations of vehicular gas emissions, without considering vehicular aerosol-emissions in the WRF-Chem (version 4.0) model in Lima, which was used as the sensitivity experiment.

The control case in the WRF-Chem model results hourly variations in the PM2.5 concentration dataset for the same site of the four automatic air-quality monitoring stations (AAQMS) in the Metropolitan Area of Lima and Callao (MALC).

The sensitivity scenario in the WRF-Chem model results hourly variations in the PM2.5 concentration dataset for the same site of the four automatic air-quality monitoring stations (AAQMS) in the Metropolitan Area of Lima and Callao (MALC).
