Low cost air quality sensors “PurpleAir” calibration and inter-calibration dataset in the context of Beirut, Lebanon

PurpleAir sensors are low cost commercially available PM2.5 and PM10 sensors.
All data is collected at the campus of the American University of Beirut in Beirut, Lebanon
All data is reported on an hourly interval.
The purpose of the collected data is twofold: (1) To assess the accuracy of the low-cost PurpleAir sensor against a high-fidelity Met One EBAM-PLUS instrument and (2) to assess the inter-sensor variability between multiple PurpleAir sensors installed at a single location.
------------------
SingleSensor_CalibData.csv:
Hourly data from low cost PM2.5 and PM10 PurpleAir sensors and high-fidelity Met One EBAM-PLUS instruments from date: July 1, 2020 to September 30, 2020.
Columns:
(A) Time_Beirut: Date and Time (Local Beirut Time)
(B) PM2.5 ConHR (ug/m3): PM2.5 hourly concentration reading from MET ONE EBAM PLUS instrument
(C) PM10 ConHR (ug/m3): PM10 hourly concentration reading from MET ONE EBAM PLUS instrument
(D) meanAB_2_5: PM2.5 reading (ug/m3) of PurpleAir sensor. The value is the average of both channels A and B from the sensor.
(E) meanAB_10: PM10 reading (ug/m3) of PurpleAir sensor. The value is the average of both channels A and B from the sensor.
------------------
MultiSensor_IntercalibrationData.csv:
Hourly data from thirteen PurpleAir sensors. Date range: June 28, 2020 to July 11, 2020
Columns:
(A): Time: Date and Time
(B) - (AS): PurpleAir sensor data for PM2.5 and PM10 in units (ug/m3). Each individual sensor is identified by the prefix "S_X" where "X" represents the channel number. Each sensor has 4 columns: PM2.5A, PM2.5B, PM10A, PM10B where 'A' and 'B' represent the individual channels in each sensor.

紫空气传感器为市场上可获得的低成本PM2.5和PM10传感器。所有数据均收集于黎巴嫩贝鲁特的美国大学校园内。数据以每小时为间隔进行报告。收集数据的目的是双重的：(1) 评估低成本紫空气传感器与高精度Met One EBAM-PLUS仪器的准确性；(2) 评估单一位置安装的多台紫空气传感器之间的传感器间变异性。

SingleSensor_CalibData.csv：
自2020年7月1日至2020年9月30日，从低成本PM2.5和PM10紫空气传感器以及高精度Met One EBAM-PLUS仪器收集的小时数据。
列：(A) 时间_贝鲁特：日期和时间（当地贝鲁特时间）；(B) PM2.5 ConHR (ug/m3)：来自MET ONE EBAM PLUS仪器的PM2.5每小时浓度读数；(C) PM10 ConHR (ug/m3)：来自MET ONE EBAM PLUS仪器的PM10每小时浓度读数；(D) meanAB_2_5：紫空气传感器的PM2.5读数（ug/m3）。该值是传感器A和B两个通道的平均值；(E) meanAB_10：紫空气传感器的PM10读数（ug/m3）。该值是传感器A和B两个通道的平均值。

MultiSensor_IntercalibrationData.csv：
来自十三台紫空气传感器的小时数据。日期范围：2020年6月28日至2020年7月11日。
列：(A)：时间：日期和时间；(B) - (AS)：紫空气传感器的PM2.5和PM10数据（单位：ug/m3）。每个单独的传感器通过前缀“S_X”进行标识，其中“X”代表通道号。每个传感器有4列：PM2.5A、PM2.5B、PM10A、PM10B，其中‘A’和‘B’代表传感器中的每个单独通道。
