Atmospheric total gaseous mercury concentration in Guiyang: Measurements intercomparison with Lumex RA-915AM and Tekran 2537A
Bibliographic record
Abstract
From May 12 to June 19,2010,a high-time resolution observation on the atmospheric total gaseous mercury(TGM) concentration in an urban area of Guiyang was continuously conducted by using Lumex RA-915AM(made in Russia) and Tekran 2537A(made in Canada).Though the two sampling instruments have distinct operation principles,the overall characteristics and temporal distribution patterns of measured atmospheric TGM concentration were quite consistent,indicating that both of the instruments could accurately measure the atmospheric TGM concentration.The atmospheric TGM concentration in Guiyang was much higher than the mean global background value,and also,higher than the atmospheric TGM concentration in urban areas of Europe and North America.The preliminary sources identification suggested that the point source mercury emission from domestic activities played an important role in affecting the atmospheric TGM concentration in Guiyang,and some large factories located at the east of Guiyang were also the important sources to the regional atmospheric mercury.

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.
