Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

aboutThe title or abstract carries a Canadian signal from the geographic lexicon.
no affNo Canadian affiliation: this work is invisible to an affiliation-only frame.
No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

We are provoding a set of table and maps that provides summary of ecosystem carbon balance (pools and fluxes) as simulated by the Dynamic Organic Soil version of the Terrestrial Ecosystem Model. Simulations are provided for the historical period from 1950 to 2009 and projections from 2010 to 2099, for the four main landscape conservation cooperative regions in Alaska (i.e. the Arctic, the Western Alaska, the North Pacific and the Northwest Boreal LCCs). Projections have been conducted at 1km-resolution for two set of climate scenarios for the A1B, B1 and A2 emission scenarios of the Intergovernmental Panel on Climate Change Special Report on Emissions Scenarios (IPCC-SRES). The two global circulation models used for these projections are (1) the 5th generation of the ECHAM general circulation model from the Max Planck Institute for Meteorology (ECHAM5), and (2) the fourth generation global circulation model from the Canadian Centre for Climate Modelling and Analysis (CCCMA). Pools and fluxes are summarized for uplands and lowlands separately. Vegetation carbon pools only concern living biomass. Soil carbon pools include organic layers, 1m deep mineral layers and dead woody debris. Positive fluxes indicate carbon assimilated to the ecosystem. Negative fluxes indicate carbon released to the atmosphere. Carbon fluxes are vegetation Net Primary Productivity (NPP), soil Heterotrophic respiration (HR), CO & CO2 and CH4 fire emissions from organic layer and vegetation burning (PYRO_COCO2 and PYRO_CH4 respectively), biogenic CH4 fluxes (BIO_CH4) and Net Ecosystem Carbon Balance (NECB).

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

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.
