One of the most popular products generated by the SOLAR2000 irradiance model
is today's most recent index to Solar UV/EUV; the nowcast E10.7. In units
of the traditional F10.7, E10.7 represents a superior index to the physical
energy input to the ionosphere and thermosphere.In the plot below, The bottom
figure is the E10.7 for approximately the past two solar rotations leading
up to today's estimated value. The bottom figure is a 'validation' plot where
the nowcast E10.7 is compared to 1996-2000 historical values, providing a
degree of verification.
