Abstract

fetched live from OpenAlex

Land water storage changes over 27 large river basins worldwide are calculated from updated monthly RL04 GRACE geoid solutions computed at GFZ from January 2003 to December 2007.Neighborhood basins show similar seasonal phase.The results indicate that the seasonal amplitude in land water storage is 1572.4 km~3 from January 2003 to December 2007.The largest annual water volume change is found in the Amazon basin,followed by the Ob,Nile and Niger. Over the 5-year time span,the inter-annual change is about -75.4±40.3km~3/a,while positive trends shown in the Amazon,Lena and Mckenzie basins,and negative in Congo,Mississippi, Yukon,Ganges and Yarlung Zangbo basins.The inter-annual change in land water storage has been increasing since 2006 from both GRACE and GLDAS.

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.
