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.

Paper Description
The enhanced greenhouse effect can be considered one the greatest global environmental concerns. The amount of radiation absorbed by greenhouse gases is known to high certainty, absorbance from atmospheric aerosols particles is not. Experiments were aimed at the study of the chemical composition of secondary organic aerosols (SOA). The SOA were created in a temperature controlled chamber at Pacific Northwest National Laboratory (PNNL) and collected on filters. The SOA were then analyzed for chemical composition using Fourier Transform Spectroscopy (FTIR). Analysis of the FTIR showed that certain peaks were degrading over time while others had increased. Peaks at >2350 cm-1 had decreases in absorbance overtime. However, at wavelengths <1600 cm-1, absorbance increased. After relating the areas under these peaks, we were able to model a clear relationship between time and the individual absorbance peaks.
