We also present the size distribution of the aerosol particles within a diameter range of 0.35 - 40 micron, measured by the OPC of the pm-modulair. However, we encourage caution while using the size distribution data, since it is operated only with the factory calibration.

| Abstract: | We deployed another PM sensor (Modulair-PM, QuantAQ) to measure the mass concentration of particulate matter (PM) for three size cuts at both the main site (M1) and supplementary site (S2) of the SAIL from 14 June 2022 to 14 June 2023. The instruments provide the mass concentration of PM1, PM2.5 and PM10. Mass concentrations were calculated based on measurements made with a nephelometer and an OPC. We used Quant-AQ's algorithm [please see their documentation here and the references within] to determine the mass concentrations reported. Here, we present the time series of sample relative humidity, temperature, pressure, and the mass concentration of PM1, PM2.5 and PM10. We also present the size distribution of the aerosol particles within a diameter range of 0.35 - 40 micron, measured by the OPC of the pm-modulair. However, we encourage caution while using the size distribution data, since it is operated only with the factory calibration. Abstract and description of the campaign can be found here : https://www.arm.gov/research/campaigns/amf2022ssb. |
| Purpose: | The purpose of this data set is to characterize and quantify the contribution from sub and supermicron particles in a mountainous region. The data was collected over a year time period to determine diurnal and seasonal variability. More information on this campaign can be found here: https://www.arm.gov/research/campaigns/amf2022ssb |
| Data Usage: | SAIL_PM_M1.csv and SAIL_S2_PM.csv provides the time series of sample relative humidity, sample temperature, sample pressure, and the mass concentration of PM1, PM2.5 and PM10 for the respective site. This data sets are already processed by Quant-AQ using their algorithm. Time is in ISO format. The variable names are self explanatory. SAIL_S2_SizeDistribution.csv file provides the size distribution of the particles using 24 diameter Bins. The diameter range of each bin is discussed in the readme file. For any further details of the variables, please read the readme.md files. |
