Abstract :
Airborne radiometer measurements were made at L-band over conifer forests in Virginia to study radiometer response to biomass and soil moisture. The horizontally polarized synthetic aperture radiometer, ESTAR, was deployed aboard a NASA-P3B Orion aircraft. Measurements were made in July, August and November of 1999 over relatively homogeneous conifer stands of varying biomass. Concurrently with the aircraft measurements, soil moisture measurements were made in several of the imaged stands. The images of the area show a strong correlation between forest stand biomass and radiometric brightness temperature. In addition, stands growing in soils with poor drainage were identifiable on the image
