The Northstar Aspen Grove station was installed in 2015. Located at an elevation of 8,050ft (2,450m), this station is predominately surrounded by an aspen ecosystem. This station is solar powered, and data are transmitted several times daily.
Soil at a Glance:
Clay Loam | 16.6% organic matter | 5.0 ppm NO3 | 20.5 ppm P | pH 6.9
Air Temperature | Relative Humidity | Rain | Soil Moisture at 2, 8, and 20in (5, 20, and 51cm) | 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 has not been calibrated. Archived data have been cleaned and calibrated, but rain readings should not be considered accurate when temperatures are below freezing.
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.
The Northstar station is managed by AGCI with funding from the Pitkin County Open Space and Trails.
