Monitoring and Modeling the Soil‐Plant System Toward Understanding Soil Health

open access: yesReviews of Geophysics, Volume 63, Issue 1, March 2025.
Abstract The soil health assessment has evolved from focusing primarily on agricultural productivity to an integrated evaluation of soil biota and biotic processes that impact soil properties. Consequently, soil health assessment has shifted from a predominantly physicochemical approach to incorporating ecological, biological and molecular microbiology

Harmonization of GEOV2 fAPAR time series through MODIS data for global drought monitoring

open access: yesInternational Journal of Applied Earth Observation and Geoinformation, 2019
The temporal consistency of the fAPAR GEOV2 full time series (constituted by data derived from SPOT-VGT1/2 and PROBA-V) is analyzed against the single-sensor MODIS dataset, with a particular focus on the most recent fAPAR anomalies (z-scores) produced from PROBA-V in the period 2014-2017.
