|This data set provides Synthetic Aperture Radar (SAR) images for 42 selected sites from various monitoring networks including Fluxnet, Ameriflux, LTER, and the Greenland Climate Network (GC-Net).There is at least one image for all 42 sites and six sites have multiple images. The scenes are in GeoTIFF format in Universal Transverse Mercator (UTM) projection and 15 meter resolution.The SAR images are subset scenes of approximately 60 km x 70 km that includes an established site in one of the monitoring networks. These scenes are distributed as 3 band geotif files with appropriate projection information defined within the file. The acquisition mode for all data is the Fine Beam Double Polarization or FBD with the HH/HV polarization. The HH and HV channels are distributed as 3 channels to allow for an intuitive image display. The HH band is displayed in the red and blue channels and the HV band is displayed in the green channel. The source of the data is the PALSAR (Phased Array type L-band Synthetic Aperture Radar) sensor flying on the Advanced Land Observing Satellite (ALOS). The PALSAR data are in dual Polarization, HH+HV, mode. Bands HH (red and green) and Band-HV (blue) can be used to visualize land use patterns. The resulting images show vegetation in shades of green and barren land in shades of pink or purple. The backscattering coefficient or Normalized Radar Cross Section (NRCS) are also provided as gray scale images.
