Snow Density Monitoring

Source: L2 GDR-A (all acquisition modes) · Variable: snow_density_01

Snow density at 1 Hz. Baseline-E: a fixed average value for all records. Baseline-F: interpolated from a monthly model file. Unused (fill value) in LRM mode.

Statistics use every 1 Hz measurement of the cycle within each area. Std Dev is the population standard deviation, RMS the root mean square.
