Soil at a Glance
Clay Loam | 10.8% organic matter | 3.1 ppm NO3 | 11.2 ppm P | pH 7.3

Live data are collected every 20 minutes and transmitted every four hours and can be found by clicking the buttons above. These data have not been checked for anomalies or potential false readings and soil moisture has not been calibrated. The snow depth sensor is only accurate to a tenth of an inch (one decimal place). In summer months, grass may distort snow depth readings.
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.
