Helmholtz-Zentrum Hereon (Hereon) has installed their coherent-on-receive marine X-band radar at the U.S. Engineer Research and Development Center's (ERDC) Field Research Facility (FRF) in Duck, NC for the During Nearshore Event EXperiment (DUNEX).

Hereons coherent-on-receive marine X-band radar provides binary raw data (processing level 0) which can be used to extract georeferenced space-time observations of the backscatter intensity and Doppler velocity (processing level 1) resulting from the surface scattering. Interpretation of this data then yields geophysical information (level 2) on wind, waves, currents and bathymetry.

Please Note: This overview aims to introducing the radar products that are generally available during (and after) the DUNEX full experiment in October 2021. Most products are well validated at other sites, but in-depth validation for the DUNEX domain will be carried out in the follow-up phase of the experiment. During this initial phase processed data will be available to DUNEX participants on request.

Data overview for DUNEX

level 0	level 1	level 2
Radar raw data	Cartesian image stacks and Time-range diagrams	Surface features / Depth maps / Current maps / Dissipation transects / Directional wave spectrum
raw binary files containing I and Q channel as recorded by the the digitizer	Matlab or netcdf containers with processed and georeferenced data (backscatter intensity and Doppler velocity)	Geophysical quantities derived from the level 1 data

More details about available radar products are on this wiki page.
