Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Comparison of climate models in an ensemble with reanalysis data is crucial for the climate model user community, as detection of discrepancies can convey information to improve models. Current comparison methodologies focus on statistical space–time properties of the climatological mean, and allow for a sensible model comparison only if the forcing scenarios are identical or very similar. We analyze the annual and seasonal surface temperature of the CMIP5 ensemble and three reanalysis data products, and propose a scenario-independent, statistical-based classification relying on the space–time structure of the variability around the climatological mean. This approach exploits the gridded geometry of the atmospheric component of a global climate model, complements traditional criteria based on characteristics of the climatological trend and allows for a novel measure of similarity. For models with a similar physical scheme, we found a high degree of similarity for the same grid resolution, and a moderate similarity if the resolution is different. Further, we found that a considerable difference among reanalysis data products, thus indicating that different assimilation algorithms can significantly impact the space–time structure of the variability around the mean climate.
