Turbulent fluxes and transfer of carbon dioxide in Arctic at the SEARCH station Eureka, Canada
Bibliographic record
Abstract
The SEARCH program has been conceived as a broad, interdisciplinary, multiscale program with a core aim of understanding the recent and ongoing, decadal, pan-Arctic complex of interrelated changes in the Arctic. These changes include, among other things, a decline in sea level atmospheric pressure, an increase in surface air temperature, cyclonic ocean circulation, and a decrease in sea ice cover. NOAA is one of eight federal agencies participating in the implementation of SEARCH. The primary observation sites are Alert and Eureka, Canada; Barrow, USA; Tiksi, Russia; Ny-Alesund, Norway; and Summit, Greenland. Several long-term research observatories near the coast of the Arctic Ocean have been identified for enhanced instrumentation to monitor the changing Arctic climate. Eureka site (80.0°N, 85.9°W) is a small research base on Slidre Fjord on Ellesmere Island in the Canadian territory of Nunavut established in 1947 as part of Arctic weather stations network. Beginning in 2004, remote sensors and in-situ instrumentation were installed at Eureka in framework of the Surface Fluxes at Study of Environmental Arctic Change (SEARCH) Program. Instrumentation at Eureka has included a cloud radar and lidar to monitor the cloud macro and microphysical properties and a 10-m flux tower instrumented at various heights for surface-layer turbulence measurements. Sonic anemometers are located at 3 and 8 m heights while high-speed Licor 7500 infrared gas analyzer (water moisture and carbon dioxide measurements) at 7.5 m height. Standard eddy covariance techniques were applied to calculate the turbulent fluxes. The thermal profile is measured by several slow T/RH sensors and differential temperature pairs at 2, 5 and 10 m heights.

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.
