Description
Summary:The European Space Agency first Remote Sensing Satellite, offers the first opportunity to monitor a complete seasonal cycle for an Alaskan forest ecosystem using a spaceborne C-band frequency VV-polarization (vertical transmit, vertical receive) synthetic aperture radar. During the 3-day repeat Commissioning Phase of from August 1991 to December 1991, 1 SAR data were collected in the region of Manley Hot Springs, Alaska, along the Tanana River, west of Fairbanks. In parallel with the SAR data collection, meteorological data from three weather stations positioned in three forest stands, along with measurements of the dielectric and moisture properties of the canopy and of the ground cover have been collected. The data collection was in floodplain forest stands dominated by balsam poplar, white spruce, and black spruce. The largest changes in radar backscatter (about 3 to 4 dB) are detected in early winter as a result of freezing of the soil and vegetation, These changes are explained u.
