Stream and air temperature are measured in tandem at stream gauging stations and other selected locations and stream confluences within the Andrews Forest. Air temperature is generally measured over the stream or alongside. Currently, mean, max and min water and air temperature data are collected every 5 minutes at the gauging stations and instantaneous temperatures every 15 minutes at all other sites. Most measurements were collected hourly commencing in the later 1990s, but a few sites have daily data beginning in the late 1970s. Historic data collected 1949 to 1981 at Lookout Creek stream gauge are included with the daily summary data.
Other Andrews Forest related databases: Long term air temperature data from the reference and benchmark climate stations are also available in MS001. Previous high resolution stream temperature data at some of the small watershed stream gages are available in HT001 and stream temperature data throughout the Andrews Forest stream networks during several years are available in HT002.
