文摘
- •
A novel automated two-step extraction method for lake ice phenology is proposed.
- •
The first step makes use of NIR and the second step uses TIR derived LSWT data.
- •
LSWT thresholds are derived from the data itself.
- •
This avoids the definition of arbitrary or lake specific thresholds.
- •
The method was validated for European lakes located in different climate regimes.
