soil respiration measurement
Continuous measurement of soil CO2 concentrations at multiple depths using automated sensors to calculate soil CO2 fluxes via gradient approach. Includes soil temperature and moisture monitoring for e...
5TE soil sensor monitoring
Continuous automated monitoring of soil temperature, moisture, and gas concentrations at multiple depths using sensor arrays. Provides high-resolution temporal data on soil microenvironmental conditio...
Nondestructive plant size measurement for biomass prediction (Asteraceae)
Systematic measurement of plant morphological characteristics (leaf number, leaf area, stalk count, etc.) before plant extraction to develop predictive relationships with total plant biomass. Differen...
Specific leaf area (SLA) measurement
Standard protocol for measuring leaf traits by scanning fresh leaves, counting trichomes using ImageJ, then drying and weighing leaves to calculate specific leaf area. Uses ImageJ software for digital...
Densiometer canopy coverage estimation
Vegetation greenness assessment using Green Chromatic Coordinate as proxy for evapotranspiration rates. Calculates green reflectance normalized by total visible flux from masked vegetation areas.
eddy covariance
Standardized eddy covariance measurements of carbon dioxide, water vapor, and energy fluxes between ecosystems and atmosphere. Continuous automated measurements providing ground truth data for model t...
Snow energy and mass balance monitoring
Continuous hourly monitoring of meteorological variables including wind, temperature, humidity, snowpack depth, and radiation components using tower-mounted instrumentation.
UAS microwave radiometry
Soil moisture measurements using the Lobe Differencing Correlation Radiometer (LDCR) L-Band microwave radiometer flown on aerial platforms.
