Compared with the ensemble - averaged phase function for spheroids, that for a shape distribution of cylinders shows a
relatively deeper minimum at side - scattering angles.
4, No. 1 February 2012: Abstract: «We can expect the onset of a deep bicentennial minimum of total solar irradiance (TSI) in approximately 2042 ± 11 and the 19th
deep minimum of global temperature in the past 7500 years — in 2055 ± 11.»
«If we get such
a deep minimum, then people need to be informed,» he says.
The solar minimum that began in approximately 2007 and reached its lowest point in December 2008 was
the deepest minimum in at least a century.
With 262 days, 2009 falls just short of 2008 but it still makes it in the top 5 of years with most blanc suns, testifying of
the deep minimum prior to the onset of SC24.
