文摘
- •
Active subspaces identify important input parameters and how they relate to output.
- •
Proof-of-concept domains show potential for dimension reduction of land surface.
- •
Important land surface parameters depend on land cover and flux type.
- •
Land surface inputs and energy flux outputs can be related by a quadratic polynomial.
- •
Lateral flow has negligible effect on the land surface parameter–flux relationship.
