Terrestrial Ecology

To help increase understanding of synthetic aperture radar (SAR) and promote its use as a powerful tool for terrestrial ecologists, ASF offers examples of data that can be used for a variety of purposes. The data are subsets for selected field sites — such as flux tower locations — from the PALSAR (Phased Array L-band Synthetic Aperture Radar) sensor flown on the Advanced Land Observing Satellite (ALOS). This dataset provides SAR images for 42 selected sites from various terrestrial-ecology and meteorological-monitoring networks, including FLUXNET, AmeriFlux, Long Term Ecological Research (LTER), and the Greenland Climate Network (GC-Net).

Figure 1. SAR images for (a) Walker Branch Watershed, Tennessee, and (b) Niwot Ridge, Colorado, sites. In SAR visualizations for land use, green usually represents tree canopy, pink is crop or barren soil, black is water, and grays are low vegetation. The star icon indicates the location of the field site.
