The Glassier Ranch Station was installed and began collecting data in the summer of 2014. Located at an elevation of around 6,460 feet (1,970m), the station is in a riparian zone near the Roaring Fork River and is surround by tall grasses. This area was heavily impacted by ranching and agriculture previous to its current ownership by Pitkin County Open Space and Trails, and its soil moisture content may still be impacted by nearby irrigation. This station is powered by solar panel.

Soil at a glance:

Sandy Loam | 33.6% organic matter | 9 ppm NO3 | 100 ppm P | pH 6.3


Air Temperature | Relative Humidity | Soil Moisture at 2, 8, 20, and 40in (5, 20, and 51, 102cm) | Soil Temperature at 8in (20cm)

Live data are collected every 20 minutes and transmitted every four hours. These data have not been checked for anomalies or potential false readings and soil moisture readings are not calibrated. Rain readings should not be considered accurate when temperatures are below freezing. 

UPDATE June 13, 2022: Cellular transmission from this station are temporarily stopped as we transition from 3G to 5G capable logger boxes, currently on-order. Data are still being collected, however, until the transition is complete, these data can only be downloaded manually. Please contact Elise to request the most current available data.

Archived data offer daily averages or daily maximum and minimum readings for each sensor. These data have been calibrated and undergone basic QC. However, rain readings should not be considered accurate when temperatures are below freezing.

Archived data available through CUAHSI (linked below) are updated annually.


This station was funded by: Pitkin County Open Space and Trails. It was installed and is operated by AGCI.
