Soil Moisture Dynamics: A Comparison of the SMOS Satellite to the South Fork In-Situ Network
This study will compare the soil moisture dynamics seen from the SMOS satellite to an in-situ network of soil probes that represent a single SMOS footprint. Using the United States Department of Agriculture's South Fork data collection site, this study will compare soil drying as observed by the five centimeter depth soil probe network to SMOS observations. Using the statistical analysis of auto-correlation, this study will show how the soil moisture from SMOS and the in-situ networks change during the few days following a rain event with data throughout the months of April through October. My hypothesis is that soil drying in the Midwest is depicted differently by measurements from SMOS compared to the in-situ network because SMOS averages the soil moisture through a five centimeter layer and within its footprint to remove the bias created by soil probes.
