Abstract. A major source of uncertainty in both climate projections and seasonal forecasting sea ice is inadequate representation surface–atmosphere exchange processes. The observations needed to improve understanding reduce surface parameterizations are challenging make rare. Here we present a large dataset ship-based measurements momentum (surface drag) the vicinity from Arctic Clouds Summer ...
Satellite drag-coefficient is a highly dynamic parameter that captures the physics of interactions between atmosphere and satellite surface. Physical models, known as Gas-Surface Interaction Models (GSIMs), can be used to compute time variations in orbit. But many input parameters such models are not accurately, consequently introduce uncertainties drag-coefficient. This work outlines framework...
In this appendix, I discuss the differences in the estimates of the model that I use in this paper (baseline model) with the estimates of a random coefficient logit model. Table 7 shows the results of the estimation of both models using the subsample of customers who always purchased Diet Coke products. The table shows that the coefficients on price and the refillable dummy are not statisticall...
BACKGROUND Postlaunch data on medical treatments can be analyzed to explore adverse events or relative effectiveness in real-life settings. These analyses are often complicated by the number of potential confounders and the possibility of model misspecification. METHODS We conducted a simulation study to compare the performance of logistic regression, propensity score, disease risk score, and...
