The GRACE Intermediate Field 48 (GIF48 from UT-CSR) field model is an improved mean gravity field that combines GRACE observations and terrestrial gravity information The terrestrial gravity information was taken from the DTU10 global gravity field. Shown here are the so-called free air gravity deviations from an ideal ellipsoidal Earth model, in units of milli-gal. Areas colored yellow, orange, or red are areas where the actual gravity field is larger than the featureless-Earth model predicts, while the progressively darker shades of blue indicate places where the gravity field is less.

Scientists have predicted that droughts and floods will become more frequent and severe as our planet warms and climate changes, but detecting this on regional and continental scales has proven difficult. Now a new NASA-led study confirms that major droughts and pluvials – periods of excessive precipitation and water storage on land – have indeed been occurring more often.
