Weather data for Douglas-fir seed-source movement trial

Data for this study were collected from 64 sensors spread across 9 sites, in Oregon and Washington, representing a range of climates. Air temperature, soil temperature, precipitation, and soil moisture were recorded on 30 minute intervals from approximately the end of 2008 through the early part of 2019. These data consist of site averages for sensors recording the same type of weather data, for a given time, at the same depth (for soil data), along with cleaned data which imputed missing data with interpolated hourly data from local data when time gaps were smaller than a day, or the nearest five weather stations from the National Centers for Environmental Information Integrated Surface Dataset network when time gaps were more than a day. These weather data were collected as part of the Douglas-fir seed-source movement trial (DF-SSMT) that began in 2008 in Oregon, Washington, and California. The DF-SSMT is a reciprocal transplant study designed to determine seed-source response of young Douglas-fir trees to changes in climate.
These data were collected as part of a reciprocal transplant study of Douglas-fir. These data were used in combination with estimates of seed-source climate to determine phenological, and trait responses to site and seed-source climates for young Douglas-fir trees. Phenological responses studied were, timing of budburst and budset, timing of diameter and height growth. Trait responses studied were cold hardiness, annual diameter and height growth, annual change in taper, and taper over time.
