Determination of External and Internal Mixing of Organic and Inorganic Aerosol Components from Hygroscopic Properties of Submicrometer Particles During a Field Study in the Lower Fraser Valley
Bibliographic record
Abstract
A tandem differential mobility analyzer (TDMA) system was developed to measure particle growth factors over a range of relative humidities from 50-85%.This system was deployed in the Lower Fraser Valley, and data was collected at Golden Ears Provincial Park and Eagle Ridge Mountain during the Pacific 2001 field study.Following humidification, particles either had a single hygroscopic mode or a bimodal distribution with more hygroscopic and less hygroscopic modes.Growth factors for the less hygroscopic mode were found to be consistent throughout the study.Monomodal distributions were the more common result.Their growth factor ranged between that of the less and the more hygroscopic modes.Using observed and calculated growth factors, relative organic and inorganic fractions were estimated.Particles at these sites were largely organic.Organic fractions near unity were found at Golden Ears forest and during rainy days at Eagle Ridge.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
