SPRUCE Atmospheric Gas and Aerosol Particle Concentrations, 2023-2024
Description
This data set contains the concentration of atmospheric gases and aerosols at the measurements from the Spruce and Peatland Responses Under Changing Environments (SPRUCE) experimental site within the Marcell Experimental Forest in northern Minnesota, USA during the summer of 2023 (2023-07-03 to 2023-08-22) and spring of 2024 (2024-04-04 to 2024-04-30). Measurements were performed in Plot 6 (control), Plot 17, (Ambient +9°C), Plot 19 (Ambient + 500 ppm CO2), and Plot 10 (Ambient +9°C and 500 ppm CO2). The main instrumentation used was the NanoScan Scanning Mobility Particle Sizer (SMPS) which measures the real-time and continuously the number concentration of minute sized particles with diameter between 10 to 420 nm. The NanoScan data set consists of 13 channels across the size distribution which provides a one-minute resolution.
During the 2024 campaign, a MODULAIR™ air quality monitor was deployed in Plots 6 and 17 to measure the concentration of particulate matter and four inorganic gases: Carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO2), and ozone (O3). Meteorological parameters temperature and relative humidity were also included in this data, which were also collected using the MODULAIR. Additionally, a dedicated ozone monitor was deployed at the SPRUCE cabin in 2023 and in Plot 6 in 2024. These data can be used to help understand the seasonal variation of new particle formation in a boreal forest environment. This dataset contains 12 data files in comma separate (.csv) format. Additional metadata are provided: 12 data dictionaries and a file-level metadata file in comma separate (.csv) format and a user guide in PDF (*.pdf) format.
