For three-day intervals, an average radar cross-section (NRCS-40) is computed for each grid point by linear regression between the measured NRCS [Normalized Radar Cross-Section] and their respective incidence angles. NRCS-40 is the value of this regression line at an incidence angle of 40°. This procedure accounts for the incidence angle dependence of the NRCS, which is highly variable in spring when the backscattering mechanism changes from volume to surface scattering depending on snow cover, snow wetness, soil moisture and the penetration depth of the microwaves. 2, record 1, English, - backscattering%20mechanism
