Abstract

fetched live from OpenAlex

Impact of Applying the Correction FactorFor most ozone stations a correction factor is provided that is derived in scaling the entire ozone column to an independent measurement of ozone column measured by a Brewer-Dobson spectrometer.Profiles that have been corrected by a factor outside the range of 0.8 and 1.2 are often ignored to not employ profiles that are heavily corrected with regard to ozone column measured by Brewer 5 and Dobson spectrometers (WMO, 1995(WMO, , 1999)).Since the correction factor was scaled with regard to the entire column, it is not necessarily valid for the tropospheric part of the profile.A comparison between MOZAIC aircraft data and ozone sondes has shown that tropospheric comparisons are better when omitting such correction factors (Thouret et al., 1998).To dismiss profiles that have been corrected by a factor outside the range of 0.8 and 1.2 has little 10 impact on the averaged ozone profiles between 1995 and 2009, as shown in Figure 1.Only those stations are shown, where the percentage difference between all profiles and only minor corrected profiles is larger than 0.5%.Differences up to 5-10% occur for a couple of stations.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
