     abstract = "{Drought is a major threat to Mediterranean water resources and it's
        monitoring increasingly requires the use of data that captures
        water conservation on land. In this study, GRACE and GRACE-FO
        satellite data were used in combination with the GLDAS land
        process model and the ERA5 reanalysis ensemble to investigate
        the dynamics of drought in Greece during the period 2002--2025.
        The GRACE-DSI and GGDI indices were calculated and compared with
        the conventional SPI, SPEI and SRI indices, while wavelet and
        Markov chain coherence analysis were applied to investigate the
        relationships between water storage and hydrometeorological
        variables, as well as the persistence of drought. The results
        show a generalized decrease in water storage in Greece, with
        groundwater depletion and soil moisture reduction being the main
        factors behind the observed trend. The strongest negative
        changes are found in the continental regions of the country,
        while temperature and evapotranspiration appear as the most
        important factors affecting the variability of water storage. At
        the same time, indicators based on GRACE data record a greater
        frequency and persistence of droughts compared to conventional
        indicators.}",
