A Preliminary Analysis of Chemical Characteristics of Atmospheric Pollutants and Their Deposition Budget on the Fu-shan Forest in Taiwan
Bibliographic record
Abstract
This paper presents the chemical characteristics of atmospheric pol lutants measured at the Fu-Shan forest (620 m MSL) during two two-weeks field experiments held in the summer and winter of 1993. Chemical com positions of these atmospheric pollutants in solid, gaseous and liquid phases were analyzed. The deposition budget of S and N compounds through dry and wet deposition pathways were particularly assessed. As a result, aero sol mass spectra were found to be bimodal, having the 50% cut size< 1.0 m and around 3.2 m for fine and coarse modes, respectively. In summer, fine and coarse modes were primarily composed of ammonium sulfate and nitrate, respectively. But, in winter the coarse mode was dominated by sea salts due to the influence of northeast monsoon flows. Our average HN02 ( -0.10 ppb) was appreciably higher than those observed in clean tropo sphere, whereas HN03 was at a comparable level. Meanwhile, ammonia gas and particulate ammonium were at a lower concentration level com pared with those generally observed on the continental grounds. The S02 ( < 1 ppb) was comparable with those frequently observed in the free tropo sphere, while SO t was close to the lowest level typically obtained in urban areas. In addition, N03-which is thought to be associated with local pollu tion was limited. Therefore, we believe that excessive SOt, to a larger extent, was transported to the site via long-range transport, particularly in winter. With regard to the deposition budget, wet deposition pathway (>

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.
