A complete step-by-step calculation using error-free synthetic gauge and satellite data.
The experiment assumes zero gauge-measurement error and zero satellite-retrieval error. Any disagreement therefore comes from spatial-support mismatch: gauges measure rainfall at points, while the satellite estimate represents an area.
The paper walks through the NCR calculation using 2,000 synthetic cases, a sparse primary gauge network, a dense withheld truth field, Hermite reconstruction, and conditional and unconditional verification examples.
