Hi organizers,

I would like to clarify a few rule-related points regarding external environmental data usage.

1. Is it allowed to extract environmental/climate variables (for example TerraClimate raster values) at observation locations, as long as raw latitude/longitude coordinates are NOT used directly as model features?
2. Are derived ecological features computed from those climate variables allowed?
3. Is pseudo-labeling using only the provided Test.csv predictions permitted?
4. Should external climate data be restricted to timestamps strictly before the observation period to avoid possible temporal leakage?

Thank you for the clarification.
