Broadband solar radiances from visible band measurements: A method based on ScaRaB observations and model simulations
Bibliographic record
Abstract
Using simultaneous and co-located broadband and narrowband observations of solar radiation from the Scanner for Radiation Budget (ScaRaB) instrument on Meteor-3 during 1994-1995, empirical relationships between ScaRaB visible band and broadband solar radiances are derived for different surface types, cloud amounts, solar zenith angles and satellite viewing angles. Relationships between ScaRaB visible channel and National Ocean and Atmosphere Administration (NOAA) Advance Very High Resolution Radiometer (AVHRR) visible channel radiances are derived from radiation transfer model simulations for different surface types and cloud cover. Combining the narrow-to-broadband (NTB) and narrowband-to-narrowband (NTN) relationships, broadband solar radiance can be derived from narrowband radiances measured by the AVHRR on operational meteorological satellites. The derived NTB conversion coefficients are evaluated against independent data. Radiances are converted to fluxes by the application of angular distribution models. Typical differences between fluxes derived from ScaRaB narrowband and broadband channels are of the order of 1 W m-2 with standard deviations of the order 15 W m-2.

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.
