description: |
  Rate of net carbon fixation by primary producers — gross primary productivity
  minus autotrophic respiration. In-situ measurement via eddy-covariance flux
  towers (FLUXNET, ICOS, AmeriFlux, NEON, OzFlux); satellite proxies via MODIS,
  Sentinel-2/3, and the new EE flux-tower constellations. Anchors carbon-market
  MRV and EU LULUCF reporting.
