🔍 More highlights:

- Height time series captures local forest growth, validated with ALS.

- Species-specific height–age curves consistent with field data.

🔍 Highlights:

- Yearly forest height, AGB, and GSV maps (2018–2024) at 10–30 m resolution in France.

- Canopy height validated with NFI data (MAE = 3.07 m).

📍 At the Hesse forest site (FR-Hes @icos-ri.eu), this method reveals:
– higher summer carbon uptake (+2 ± 1 µmol/m²/s)
– better nighttime respiration estimates
– strong agreement with standard EC

Implemented in TurbulenceFlux.jl (Julia)

@gbrldst.bsky.social introduces a wavelet-based method to analyze turbulent fluxes in time & frequency, using a metric based on the vertical Reynolds stress tensor to adaptively localize turbulence.
This helps separate turbulence from advection.

🌍 Flux towers are essential for tracking CO₂, water vapor, and heat exchange between ecosystems and the atmosphere.
But traditional 30-min eddy-covariance averaging often misses rapid responses to environmental change.
