Earth system history is adiverseand complex science. Students of Earth system history are not just concerned with documenting what has happened; they also view the past as a series of experiments in whichsolar radiation,ocean currents, continental configurations, atmospheric chemistry, and other import...
Wildfire: Created by Michael Piller, Christopher Teague. With Genevieve Padalecki, Nicole Tubiola, Nana Visitor, Greg Serano. A ranch family gives Kris Furillo, a troubled teenager, a second chance at a life.
In applications, two main assumptions of PCMCI are causal sufficiency and time series stationarity. The first assumption can be satisfied by considering as many relevant variables as possible. Normally, causal discovery is more reliable when more variables are included. But when too many irrelevant ...
Some of the most destructive wildfires in California history have taken place in the last 10 years. Experts base the worst fires on how many acres are burned. In 2020, the August Complex fire burned over 1 million acres, making it the largest wildfire in California history. Most...
Our impact and recovery metrics were derived from time series of modeled annual canopy cover. A gradient boosted regression model (GBM) was developed to predict canopy cover from five spectral indices and three topographic variables. The model was trained on forest cover measurements derived from ten...
gridpoint (to an average of zero and standardized deviation of 1) and then averaged all standardized gridpoint time series. In the same way, we developed regional WFAC fire chronologies for the ten fire regions (details below). Fig. 1: Spatiotemporal fire occurrences of the Wildfire Atlas of...
The red sun and moon over northeastern U.S. states this week came with a series ofair quality alertsthat impacted millions of people over the weekend and into Tuesday, some living as far west as Minnesota, Montana and Nebraska. The alerts stretched across to the east coast as hazy skies ...
This work is 38″ w X 23″ t. It is part of the memorrie map series about my childhood. The town represented is Carroll Iowa and we lived in this town for 5 years. Playing marbles and learning to ride a bike were important events in those years. Gene and I also spent a lot of...
“chngpt” package96was used to fit 2-segmented linear trends to PM2.5flux-weighted average plume top height, PM2.5mass injection relative to the PBL, and PM2.5emissions timeseries. Significant hinge-points were selected using a bootstrapping procedure that identifies the optimal hinge, with an...
We generate 1000 block-bootstrapped series of the same length as the original series and calculate the quantile q at which the test statistic (S or KT) calculated from the original data lies in the bootstrapped sample. The p value is then p = 1 − q. ...
