Comparison of Surface Reflectance Retrieved from Hyperspectral Data Using MODTRAN4 and CAM5S
Bibliographic record
Abstract
The present investigation evaluates surface reflectance retrieved from Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) and Compact Airborne Spectrographic Imager (casiTM) data using the CAM5S and MODTRAN4 atmospheric radiative transfer (RT) codes. The retrieved surface reflectances were compared with ground-based reflectances acquired with a GER3700TM spectroradiometer for a playa and canola target. The results showed that the best overall performance was achieved with MODTRAN4. Major differences occur in the stronger gas absorption regions. At wavelengths unaffected by strong gaseous absorption, the performance was similar for both RT codes even though CAM5S has an execution time that is about about 50 times faster than that of MODTRAN4.

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.
