| Popis: | This study examines the impact of variation in Root‐Zone Soil Moisture (RZSM), a key component of the Earth's hydrologic cycle and climate system, on regional carbon fluxes across seven North American ecosystems. P‐band Synthetic Aperture Radar‐derived RZSM estimates were incorporated into the Ecosystem Demography (ED2) terrestrial biosphere model through a model‐data blending approach. Analysis shows that the model qualitatively captures inter‐daily and seasonal variability of observed RZSM at seven flux tower sites (r=0.59 ± 0.26 and r= 0.70 ± 0.22 for 0‐10cm and 10‐40cm soil layers, respectively; P |
