Abstract Polarization phase-curve measurements provide a unique constraint on the surface properties of asteroids that are complementary to those from photometry and spectroscopy have led identification “Barbarian” as class objects with highly unusual surfaces. We present new near-infrared polarimetric observations six Barbarian obtained WIRC+Pol instrument Palomar Hale telescope. find dramatic...

Irrigated agriculture in South Asia depends on meltwater, monsoon rains and groundwater. Climate change alters the hydrology causes shifts timing, composition magnitude of these sources water supply. Simultaneously, socio-economic growth increases demand. Here we use a high-resolution cryosphere–hydrology–crop model forced with an ensemble climate projections to assess how irrigation supply may...
