Web9 de ene. de 2024 · Due to the small-scale and nonstationary nature of CGs, reliable CGs nowcasting with high spatial and temporal resolutions has remained unattainable. In this study, a novel nowcasting model based on deep learning – namely, CGsNet – is developed for 0–2 h of quantitative CGs nowcasting, first achieving minute-kilometer-level forecasts. WebHere we present a deep generative model for the probabilistic nowcasting of precipitation from radar that addresses these challenges. Using statistical, economic and cognitive measures, we show that our method provides improved forecast quality, forecast consistency and forecast value. WebThe KOF Nowcasting Lab consists of three interrelated parts: A real- time database in which the daily data status of over 3,000 time series is stored. The data status that a forecaster had on a given day can therefore be replicated at any time and tested using new methods. A website that clearly displays the forecast output. cliffview pty ltd
