SnowEx17 SnowSAR Multi-look Synthetic Aperture Radar Backscatter Amplitude Images V001

공공데이터포털

This data set, part of the SnowEx 2017 campaign, contains multi-look synthetic aperture radar (SAR) amplitude images. The images are stored in netCDF files; browse images are also available. Data were collected using the SnowSAR instrument at the X (9.6 GHz) and Ku (17.25 GHz) bands. The SnowSAR instrument flew on the NP-3C Orion aircraft and captured data from across Colorado, including near the SnowEx 2017 Grand Mesa, Colorado study site and Vail, Colorado. Data were acquired between 16 February 2017 and 22 February 2017 and have a resolution of 1 meter by 1 meter.

SnowEx23 Mar23 Mobile Tower-Based Dual-Pol C-Band V001

공공데이터포털

This data set contains C-band radar data collected during the NASA SnowEx 2023 Alaska field campaign between 08 March 2023 to 15 March 2023. Data was acquired from two study areas near Fairbanks, Alaska using a multi-polarization radar affixed to sled-mounted tower. The study sites (Caribou Poker Creek watershed and Farmer’s Loop/Creamer’s Field) are boreal forest and wetland environments. Data was also collected from a school adjacent to Farmer’s Loop, to record data from man-made surfaces (i.e., concrete and cultivated grass.)

SnowEx17 Ground-Based UWScat Ku- and X-Band Frequency Modulated Continuous Wave Radar V001

공공데이터포털

This data set consists of ground-based scatterometer data acquired during the SnowEx 2017 campaign at Grand Mesa, Colorado, USA, a snow-covered, forested study site about 40 miles east of the city of Grand Junction, CO. The data comprise operational parameters used during data acquisition, Mueller matrices for each acquisition, and the nearfield-corrected normalized radar cross section (NRCS) in VV, VH, HV, and HH polarizations. Range profile data are also provided for each scan which report the raw power returned as a function of range from the antenna.
