Abstract

fetched live from OpenAlex

The outgoing longwave radiation (OLR) bias due to the neglect of cloud horizontal inhomogeneities has been examined in this study. It is argued that this OLR bias is most significant for semi‐transparent cirrus clouds that are located in the cold upper troposphere. Using two cirrus cases observed from cloud radar, it is found that the OLR biases due to the plane‐parallel homogeneous assumption are ∼14 W m −2 . These biases are largely caused by the horizontal variation of cloud optical depth. It is also shown that in general the OLR biases are strongly dependent on the cloud height and mean and standard deviation of cloud optical depth. We have demonstrated that the gamma‐weighted radiative transfer scheme, which is efficient for GCM applications, can be used to account for the effect of cloud horizontal inhomogeneity on the infrared fluxes.

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.
