Relaciones entre el NDVI y los flujos turbulentos de calor en un pastizal mediterráneo

Abstract

Vegetation plays a key role on the interaction between the land surface and the atmospheric processes, and its functioning could be monitored through spectral indices such as the Normalized Difference Vegetation Index (NDVI) obtained through remote sensing data. The aim of this work is to investigate the relationships between NDVI and the turbulent heat fluxes near the surface in a grassland ecosystem of Central Spain throughout a three-year period (January 2018- August 2020). Results showed that NDVI is strong correlated with sensible and latent fluxes especially during the end of growing period. Thus, including NDVI in could improve atmospheric models.
