Gas exchange for the plants on the example of coastal sedge and comparison with the materials of spectro-gasometric ground-based measurements from the UAV and the Sentinel-2 satellite

Spectro-gasometric ground-based measurements were carried out during 2020-2021. It was determined that five vegetation indices - REP (Red Edge Position), Green NRDI (Normalized Difference Vegetation Index), MOD (Green Model) and Red edge are more responsive to the presence of СО2 concentration depending on leaf photosynthesis respiration coastal sedge (Carex riparia) with high correlation under Pearson from 0.60 0.72. Certain capture changes in can be recommended for use carbon flux models canopy. Data DJI P4 Multispectral UAV, Parrot Bebop Pro Thermal Sentinel-2 satellite compared ground May 25, 2021.
