Ground-Truthing Satellite Imagery with Phenological Observations: Visual Observations from Grasslands at the Sevilleta National Wildlife Refuge, New Mexico
Phenology is the study of recurring natural phenomena. The seasonal "greening-up" and "greening-down" of dominant vegetation can be used as a predictor for a variety of processes and variables at local to global scales. The use of satellites to monitor land surface phenology is important for understanding local and regional ecosystem variability, identifying change over time, and potentially predicting ecosystem response to short and long-term changes in climate. However, the relationship between how phenology is expressed on the ground and how it is interpreted from satellites is poorly understood because phenological stages do not always correspond well to changes in spectral reflectance. In this study, we explored the relationship between greenness as measured by digital camera, the human eye, and ASTER imagery in two perennial grasslands at the Sevilleta National Wildlife Refuge in central New Mexico.
Ground observations of spring leaf emergence phenology at eight sites in and near the Coweeta basin (2011-2012).
This study was conducted to evaluate the utility of satellite data from the MODIS sensor to predict the timing of spring leaf emergence in the Southern Appalachians. Eight ground sampling sites were established on square plots (231 x 231 meters) that corresponded to the dimensions of MODIS satellite pixels. Each site was visited approximately every other day and observations on the status of leaf emergence in the canopy and understory were collected at 30 subsampling points within each site. Observations consisted of visual estimates of leaf emergence status on marked trees and shrubs, as well as digital photographs of the canopy and understory taken from consistent locations at each subsampling point.
