NASA's Forest Ecosystem Dynamics Multisensor Airborne Campaign includes the SWOE Thermal Analysis and Measurement Program (STAMP). The dataset contains detailed temperature measurements from a bigtooth aspen tree trunk, branches, and surrounding soil, collected on September 12, 1990. Measurements were taken at specific depths and heights using thermistors and thermocouples with Campbell Scientific data loggers.
Use Cases
- Develop a 3-D thermal model of trees based on trunk temperature measurements at three heights.
- Analyze temperature gradients within tree trunks based on measurements at the center and at different depths.
- Compare thermal properties of living and dead branches based on under-bark and center temperature probes.
- Study microclimate effects around a tree based on surface temperature measurements inside and outside the shadow zone.
- Model soil-vegetation energy interactions using concurrent surface and soil temperature measurements.
Strengths
- Provides highly detailed, in-depth temperature measurements at specific locations (e.g., 1/4 inch from bark outer surface).
- Includes measurements from multiple components: tree trunk (center and depths), living and dead branches, and surrounding soil.
- Data collection uses specific instrumentation (Model 101 thermistors, Type K thermocouples, Campbell Scientific CR-21/CR-21X data loggers).
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Last updated 1990-09-24 23:59:59.999000; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
Provenance

- Collection Method
- Instrumented temperature probes placed in and around a bigtooth aspen tree, logged by data loggers.
- Time Range
- 1990 (specific measurements on September 12, 1990).
