During the evaluation period (2023), submitted forecast models were most useful when in-lake conditions were most different to historical observations.
As conditions continue to move beyond what can be predicted from past observations, these forecasting methods will be more and more valuable! 📈

Skillful forecasts were generated using four model classes - process models, machine learning, empirical, and multi-model ensembles.

35-40% of models outperformed null models and the most successful models accounted for more sources of uncertainty (process, parameter, initial conditions, observational, drivers) with poor models often over-confident in their forecasts.

Using >100,000 near-term ecological forecasts, produced in real-time as part of the @ecoforecast.bsky.social NEON Forecasting Challenge, we looked at how different forecasting models performed for different lake variables and sites!
