-The Abstract and Section 1 explicitly state that the ABLES observatory was “established in 2023.” However, Section 2.3 references “A year’s observations from 2022 to 2023,” Section 3.1 details “Field campaign I (October–November 2022),” and Section 3.4 mentions “~300 flask samples collected at ABLES” from “2021 to 2022.” How could observational data and field campaigns be conducted at ABLES prior to its stated establishment year? Please clarify this timeline discrepancy.
-The text states: “Organic aerosols accounted for 43%–61% of the total PM₁, while secondary inorganic aerosol (SIA: nitrate, sulfate, ammonium) contributed 37%–49%.” The upper bounds of these ranges sum to 110% (61% + 49%), which is a physical impossibility for mass fractions of PM₁. Are these ranges aggregated across different seasons/campaigns rather than representing simultaneous mass balance, or is this a typographical error?
-Table 2 lists “Storm Peak Laboratory” (Row 2) and “Storm Peak” (Row 13) as two distinct entries. They share virtually identical coordinates (40.455°N, 106.745°W vs. 40.455°N, 106.744°W) and represent the same facility. Is this an unintentional duplication that should be merged to maintain the table’s rigor and avoid redundancy?
-In Table 1, Item 8 is titled “High-Precision Carbon Dioxide (CO₂) / Methane (CH₄) Analyzer G2401,” yet the “Parameters” column explicitly lists “CO (ppm), CO₂ (ppm), CH₄ (ppm).” Should the instrument title be corrected to include Carbon Monoxide (CO) to accurately reflect the Picarro G2401’s capabilities, or is the inclusion of CO in the parameters column a typographical error?
