Abstract

fetched live from OpenAlex

The oldest meteorological data for the southwest coast of Greenland date from the second half of the 18th century. Weather observations were conducted by the Moravian Brothers, who established the first Christian mission in a settlement called Nuuk (formerly: Neu-Herrnhut, Godthaab, Godthab or Godthåb).During their mission, the Moravian Brothers compiled two series of meteorological data: 1) Sep 1767 – Jul 1768 and 2) Sep 1784 – Jun 1792. For the first series (Neu-Herrnhut), observations were made twice a day (8:00 AM and 2:00 PM LT). Parameters such as air temperature (°F), atmospheric pressure (Paris inch and Paris line), and wind direction and force (1-6) were measured. The second series (Godthaab) consists of measurements taken three times a day (7:00 AM, 2:00 PM, and 9:00 PM LT). Air temperature (°R), atmospheric pressure (Paris inch), and wind direction and force (0-4) were measured.Historical data were quality-checked and corrected. Air temperature was converted to degrees Celsius. Atmospheric pressure to mmHg and them to hPa. The gravity correction "Pφcorr" was then applied, and the pressure was reduced to sea level altitude "SLP" using the formulas provided in Cappelan (2009). Atmospheric pressure was also corrected to the value at 0°C. For this purpose, the Kämtz formula from Können et al. (2003). For more details, see Przybylek et al. (2013). Wind speed was converted to m∙s-1 using the Beaufort scale. For more details on the conversion, see Chmist et al. (2025). New wind speed classes were defined for each series and assigned appropriate values, see Table in wind_conversion.pdf file.References: Cappelen J (ed.)

Teacher imitation

Not 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.
