The Noncontiguous Rain-Gauge Method
A highly technical working guide to verifying satellite rainfall estimates from sparse point gauges.
This technical monograph presents the Noncontiguous Rain-Gauge Method for constructing a gauge-derived areal rainfall reference distribution from sparse point rain gauges. The method addresses the support mismatch between point gauges and satellite areal rainfall estimates.
Audience note: This is a technical research monograph, unlike the general-audience books on Option Strategy Lab. The PDF is free on Zenodo; the Kindle edition is available on Amazon for readers who prefer that format.

What the NCR method covers
Gauge-to-pixel scale
Why individual gauges sample point rainfall while satellite products estimate areal rainfall over a grid cell or verification area.
Conditional distributions
How rainfall distributions can be conditioned on satellite estimate bins to evaluate calibration and verification performance.
Practical workflow
How sparse tropical-island gauge networks can still support useful satellite-rainfall verification when the scale problem is handled directly.
