Figure 11: Difference images for change in PALS LV brightness temperatures at 400 m resolution and change in AIRSAR LVV backscatter at 30 m resolution for the period July 5 to July 7 (July 5–July 7). The spatial patterns corresponding to wetting or drying are strikingly consistent in both images indicating that the AIRSAR LVV channel is sensitive to near-surface soil moisture [55].
