### Question:
SynopticUncertaintyProvider { double r(int y) { return Math.exp(-0.5 * (dxy(y) / LXY + dt())); } SynopticUncertaintyProvider(SpatialResolution spatialResolution, TemporalResolution temporalResolution); double calculate(AggregationCell cell, double a);  }### Answer:
@Test public void test_r() { SynopticUncertaintyProvider sup = new SynopticUncertaintyProvider(SpatialResolution.DEGREE_0_05, TemporalResolution.weekly5d); assertEquals(0.3646409252417634, sup.r(12), 1e-8); sup = new SynopticUncertaintyProvider(SpatialResolution.DEGREE_0_15, TemporalResolution.weekly5d); assertEquals(0.35780795774357266, sup.r(12), 1e-8); }
