Budburst data analysis

I have recently started to analyze GLOBE budburst data to answer the question "How has the timing of budburst changed over time?". I've found a couple GLOBE schools that have budburst data for at least 10 years! Some of these schools also have budburst data for more than just one species. So far in my analysis I've noticed that budburst timing is getting earlier over time, but there is a lot of variation from year-to-year. I'm going to look at other climate factors, like temperature and precipitation in particular, to see if there is a similar trend that might be causing the earlier budburst. Is anyone else doing phenology research with GLOBE data?
