What it is good for - and what it is not

The corrected product moves the daily distribution to the gauge but inherits raw satellite timing (the r ≈ 0.34 ceiling). So the useful question is not "is it accurate?" but "does your application need the distribution or the calendar day?" Pick one:

The split tracks day-specific timing, not topic: flood, hydrology and agriculture each appear on both sides. A 25-year flood-frequency analysis is well-served; real-time flood nowcasting on a named date is not - the same field, judged on different axes.
