Decagon Data Plotting/Download
Decagon data included in this visualization and aggregation tool are associated with the USDA-NIFA funded project: "Cropping Systems Coordinated Agricultural Project: Climate Change, Mitigation, and Adaptation in Corn-based Cropping Systems." (Award No. 2011-68002-30190).
By using this tool, you agree to the data usage agreement.
Plotting of data may not occur if the time period selected is more than ~700 days. This is due to the amount of data overwhelming the user’s web browser and failing to load. Select a shorter time span if you run into this problem. Long time periods can be selected without problems if only exporting the data.
Frequently Asked Questions
- How are timezones handled?
The timestamps presented should be valid for the local time zone of the sensor and are daylight saving time aware. - How the aggregation is implemented?
The hourly aggregated value is computed by averaging any available observations taken during that hour. If holes exist in the data for that hour, they are ignored/unused in the aggregation. The same procedure holds true for the daily aggregation, which represent the daily summaries in the time zone of the station.

Notes
- NAEW A rock layer prohibited sensor installation deeper than 50 cm.
- DPAC. Soil moisture is measured at a single location within each quadrant, located midway between a pair of drainage lines, and selected to be within the zone of influence of the control structure. It most likely represents the upper end of field soil moisture.
- GILMORE. Soil moisture is monitored midway between the tile lines in about the middle of the plot
- HICKS.B and HICKS.G. Soil moisture is measured at a single location within each management zone, midway between a pair of drainage lines, and reported to represent the entire zone.
- STJOHNS. Soil moisture data at 3 specific locations each in free and managed drainage areas.
