Truck-mounted L- and Ku-band scatterometers were used to collect fully polarimetric backscattering coefficients of snow. The calibrated radar systems measured the amplitude and phase of backscattered signal over a relatively wide bandwidth at L-band (1.1-1.4 GHz) and Ku-band (15.25-15.75 GHz). Backscatter measurements of an open snow pack were collected at three different incidence angles (20, 35, and 50 degrees) several times a day. This data set is part of the NASA Cold Land Processes Field Experiment (CLPX). The NASA CLPX is a multi-sensor, multi-scale experiment that focuses on extending a local-scale understanding of water fluxes, storage, and transformations to regional and global scales. Within a framework of nested study areas in the central Rocky Mountains of the western United States, ranging from 1-ha to 160,000 km2, intensive ground, airborne, and spaceborne observations are collected. Data collection focuses on two seasons: mid-winter, when conditions are generally frozen and dry, and early spring, a transitional period when both frozen and thawed, dry and wet conditions are widespread.' description_attribution: ~ display_name: 'CLPX-Ground: Ground-based L and Ku band polarimetric scatterometry' doi: 10.5067/JWGEFX2FALQR end_time: 2003-02-26T00:00:00 files: [] href: http://52.38.26.42:8080/dataset/nasa-nsidcdaac-0166.yaml identifier: nasa-nsidcdaac-0166 instrument_measurements: [] lat_max: 39.95 lat_min: 39.95 lon_max: -105.9 lon_min: -105.9 name: 'CLPX-Ground: Ground-based L and Ku band polarimetric scatterometry' native_id: NSIDC-0166 parents: [] processing_level: ~ publication_year: ~ references: [] release_dt: 2003-08-11T00:00:00 scale: ~ scope: ~ spatial_extent: ~ spatial_ref_sys: ~ spatial_res: ~ start_time: 2003-02-17T00:00:00 temporal_extent: ~ temporal_resolution: ~ type: dataset uri: /dataset/nasa-nsidcdaac-0166 url: http://nsidc.org/data/NSIDC-0166 variables: ~ version: ~ vertical_extent: ~
