Descripción
Using accurate radial velocity observations of integral sunlight, the
background solar velocity noise has been measured at different
frequencies of interest for solar oscillations within a frequency
interval between 10-7 and 10-2Hz. Comparison with
a numerical model, simulating the most important solar processes:
granulation, mesogranulation, supergranulation and active regions, with
associated velocity fields shows good agreement at the amplitudes and
their, already known, characteristic time scales.
