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).

针对利马地区的机动车排放气体与气溶胶，基于WRF-Chem（版本4.0）模型开展空气污染物与气象变量逐时观测的时空模拟，由此构建的数据集作为对照试验场景。

针对利马地区，基于WRF-Chem（版本4.0）模型仅开展机动车排放气体的时空模拟（未考虑机动车气溶胶排放），由此构建的数据集作为敏感性试验场景。

WRF-Chem模型对照试验场景的输出结果，为利马与卡亚俄大都会区（Metropolitan Area of Lima and Callao，缩写MALC）内4个自动空气质量监测站（Automatic Air-quality Monitoring Stations，缩写AAQMS）对应站点的PM2.5浓度逐时变化数据集。
