Retrieval of Aerosol Extinction in the Lower Troposphere Based on UV MAX-DOAS Measurements
Bibliographic record
Abstract
MultiAxis Differential Optical Absorption Spectroscopy (MAX-DOAS) has been utilized in recent years as a means of deriving vertical profiles of aerosol and trace gases; however, this new technique requires further validation because few studies have investigated its capability.In this study, vertical distributions of aerosol extinction coefficients (AECs) in the lower troposphere were retrieved by applying a recently developed aerosol-retrieval algorithm to O 4 slant column densities (SCDs) measured at a UV wavelength (356 nm) using the MAX-DOAS technique.The MAX-DOAS measurements were conducted at the Korea Global Atmosphere Watch Observatory (KGAWO) located off the west coast of Korea during a period of seven cloudless days in May and June 2005.The AECs measured by UV MAX-DOAS varied from 0.05 to 0.73 km -1 in the 0-1 km layer and from 0.01 to 0.20 km -1 in the 1-2 km layer.The AECs for the 1-2 km layer from UV MAX-DOAS are in agreement with lidar data within about 60%.Our results demonstrate the ability of MAX-DOAS as a remote sensing technique for surface aerosol measurements.

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.
