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), Green MOD (Green Model) and Red MOD (Red edge Model) are more responsive to the presence of С...

Ukrainian Journal of Remote Sensing of the Earth| Summary: | 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), Green MOD (Green Model) and Red MOD (Red edge Model) are more responsive to the presence of СО2 concentration depending on leaf photosynthesis and leaf respiration of the coastal sedge (Carex riparia) with high correlation under Pearson from 0.60 to 0.72. Certain vegetation indices capture changes in СО2 concentration and can be recommended for use in carbon flux models for vegetation canopy. Data from DJI P4 Multispectral UAV, Parrot Bebop Pro Thermal and Sentinel-2 satellite compared to ground measurements on May 25, 2021. |
