Like the article hints at, some of the particular strengths of this new measurement:
- frequent revisit, so can track even sub-monthly changes
- the L-band radar is at a wavelength (24cm) that penetrates vegetation canopy, removing a confounder from the measurement
- excellent spatial resolution that is relevant to urban scenes
The data volume is exceptionally high and required a lot of engineering effort. All radars are demanding, but this one was a new high-water mark.

Pun fully intended, I'm sure.
