Evidencepartial
The results show that SHADECast is the most reliable model, achieving a CRPS 10.8% lower than that of SolarSTEPS at a two-hour lead time.
Implicationpartial
This claim is explicitly stated in the abstract with specific quantitative results.

Evidencepartial
Nonetheless, state-of-the-art nowcasting models struggle to capture ramp dynamics, with forecast RMSE increasing by up to 50% compared to normal operating conditions.
Implicationpartial
This claim is explicitly stated in the abstract with specific quantitative results.
Verificationpartial

Evidencepartial
In particular, we observe that ramp-up events are typically associated with cloud dissipation during the morning, while ramp-down events commonly occur when cloud cover increases in the afternoon.
Implicationpartial
This claim is directly stated in the abstract and supported by descriptions of meteorological drivers.
Verificationpartial

Evidencepartial
In this study, we analyze two years of PV power production from 6434 PV stations at 15-minute resolution.
Implicationpartial
This claim is explicitly stated in the abstract, detailing the dataset used.
Verificationpartial

Evidencepartial
Additionally, we adopt a recently developed spatiotemporal forecasting framework to evaluate both deterministic and probabilistic PV power forecasts derived from deep learning and physics-based models, including SolarSTEPS, SHADECast, IrradianceNet, and IFS-ENS.
Implicationpartial
This claim describes the core methodology used in the study, as stated in the abstract.

Evidencepartial
Most PV installations are located in the Swiss Plateau or in valleys within the Alpine region.
Implicationpartial
This claim is derived from the description of the study's geographical scope and the figure showing elevation maps.
