There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Title: An Analysis of Monthly Mean Temperature Trends in the United States
Abstract: To study monthly mean temperature trends for the continental United States, we develop a periodic linear regression model with multiple changepoints, which allows for a mean shift at each changepoint time and simultaneously estimates both trend and changepoint effects. The error component in the model is allowed to be a periodically correlated time series. The model is applied to over 900 temperature recording stations across the U.S., and a spatially smoothed map of temperature trends is presented. Overall, the results suggest more warming than is estimated in previous studies.
