In East Asia, a positive O3 surface trend at 0.25 ± 0.17 ppb year−1 was observed at WLG for the period from 1994 to 2013 (Xu et al. 2015), and an especially strong increase was found in autumn, followed by spring.

For example, we can select a different 15-year period, 1992 2006, and find a surface warming trend nearly 50percentt faster than the multi-model average, as statistician Tamino helpfully illustrates in the figure below.
Trend is the direction of the line formed by the intersection of the planar feature with the ground surface; trend is the same as strike only if the ground surface is parallel to the horizontal plane.
The results showed in increasing surface trend, with abandonment appearing mostly in former exurban agricultural areas.
The majority of theropod trackways on this surface trend north-south, paralleling the paleoshoreline.
Missing data can be optionally removed before calculating the moving quantiles, if the missing data phases do not involve changes in surface trend.
But is this just a surface-level trend, or is paganism really having a moment?
Another big change for DataSift — the UK startup that applies analytics to social network data firehoses to surface trends, which had a notable break up with Twitter earlier this year.
The tool can surface trends and present them to users in a ranked feed.
