Laura Mihai, A. STANCALIE, ADELINA SPOREA, D. SPOREA, ARGENTINA NERTAN, D. MIHAILESCU. Drought vegetation monitoring using in situ and satellite data, in the Caracal plain of Romania. Romanian Reports in Physics, 2016.

Abstract: Drought monitoring and plant productivity can be qualitatively evaluated using
vegetation indices. In this paper, we combined in-situ reflectance, satellite and agro-meteorological
data, in order to obtain and analyze high precision indices corresponding to germination period of
some agricultural crops from the Caracal plain, Romania. Sensitivity tests regarding the effect of
detection angle and atmospheric conditions on reflectance were estimated. Differences that can be
related to the phenological stages of studied crops were noticed in near infrared spectral range. The in-situ and satellite-based results, correlated with main agro-meteorological parameters proved to be
good indicators of the drought vegetation condition.

Keywords: physics
