Product details

Name	ERICHA Hourly precipitation maps
Acronym
Description	Flash flood indicators / ERICHA - Radar-based precipitation monitoring and nowcasting flash flood indicators – 'ERICHA Hourly accumulation precipitation' layer Hourly precipitation totals from the OPERA radar composite, updated every 15 minutes (“ERICHA hourly accumulation precipitation” layer) 1-h precipitation accumulation estimated from the European OPERA radar rainfall composites. This product is displayed in a loop with 15-minute time interval. It shows the estimated precipitation for several hours in the past up to current time and nowcasts (when the loop bar turns red) up to 6 hours. Deterministic precipitation nowcasts are generated by Lagrangian extrapolation. This product was developed in the ERICHA project. Recently, a multiplicative adjustment factor map (retrieved from long-term comparison with rain gauge observations) is applied to compensate for systematic biases in the original OPERA radar rainfall estimates. The gauge-adjustment module has been developed within the SMUFF project. Output: Animated maps (15 min only); Forecast Horizon: Every 15 min up to 6 hours; NOWCAST (1)
