Fine particulate matter (PM2.5) datasets for both Indoor and Outdoor environments at two South Texans residences.

This dataset provides hourly and daily averaged measurements of PM2.5 concentrations (µg/m3) collected from two residential homes in the Rio Grande Valley (RGV), Texas, using PurpleAir-II-SD. Additionally, the dataset includes temperature (ºC) and relative humidity (%) measured by the sensors. The data was collected for one month during the summer from indoor (kitchen) and outdoor (front yard) environments at two locations: Home-1 in Weslaco from June 16, 2024, to July 16, 2024, and Home-2 in Mission from June 22, 2024, to July 16, 2024. Furthermore, the resultant wind speed and wind direction data were obtained from nearby Texas Commission on Environmental Quality (TCEQ) Continuous Ambient Monitoring Stations (CAMS), providing a broader understanding of environmental influences on air quality. The raw PM2.5 data were corrected using Barkjohn's US-wide correction equation to increase the accuracy of the measurements and are presented in the datasets. The dataset is available in three CSV files: one for Home-1, one for Home-2, and one for wind data (Wind Rose) from the TCEQ stations.

本数据集收录了来自德克萨斯州里奥格兰德河谷（RGV）两处住宅的紫空气-II-SD监测设备所采集的PM2.5浓度（单位：微克/立方米）的小时和每日平均值。此外，数据集还包含了由传感器测量的温度（单位：摄氏度）和相对湿度（单位：%）。数据采集于夏季一个月内，分别在室内（厨房）和室外（前院）环境下的两个地点进行：Home-1位于韦斯莱科，采集时间为2024年6月16日至7月16日；Home-2位于米逊，采集时间为2024年6月22日至7月16日。此外，数据中还纳入了邻近的德克萨斯州环境质量委员会（TCEQ）持续环境监测站（CAMS）提供的风速和风向数据，以更全面地揭示环境因素对空气质量的影响。原始PM2.5数据经Barkjohn的全国性校正方程校正，以提升测量精度，并在数据集中呈现。该数据集以三个CSV文件的形式提供，分别对应Home-1、Home-2以及来自TCEQ站点的风向数据（风玫瑰图）。
