  text: "The implementation of future geoengineering projects to counteract global
    warming trends or more generally changes in aerosol loads alter solar radiation
    reaching the Earth's surface. These changes could have effects on ecohydrological
    systems with impacts which are still poorly quantified. Here, we compute how changes
    in solar radiation affect global and local near-surface meteorological variables
    by using CMIP6 model results. Using climate model outputs, we compute climate
    sensitivities to solar radiation alterations. These sensitivities are then applied
    to local observations and used to construct two sets of numerical experiments:
    the first focuses on solar radiation changes only, and the second systematically
    modifies precipitation, air temperature, specific humidity, and wind speed using
    the CMIP6-derived sensitivities to radiation changes, i.e., including its land–atmosphere
    feedback. We use those scenarios as input to a mechanistic ecohydrological model
    to quantify the local responses of the energy and water budgets as well as vegetation
    productivity spanning different biomes and climates.\r\nIn the absence of land–atmosphere
    feedback, changes in solar radiation tend to reflect mostly in sensible heat changes,
    with minor effects on the hydrological cycle, and vegetation productivity correlates
    linearly with changes in solar radiation. When land–atmosphere feedback is included,
    changes in latent heat and hydrological variables are much more pronounced, mostly
    because of the temperature and vapor pressure deficit changes associated with
    solar radiation changes. Vegetation productivity tends to have an asymmetric response
    with a considerable decrease in gross primary production to a radiation reduction
    not accompanied by a similar increase at higher radiation. These results provide
    important insights into how ecosystems could respond to potential future changes
    in shortwave radiation including solar geoengineering programs."
