Date span: 1980-02-16 to 1989-06-01
Daily rows (valid): 3053
Monthly bins: 113
Annual bins: 10
TSI range: 1364.4790 to 1369.7090 W m^-2

Scale note:
  Values on the old SMM/ACRIM-I absolute scale (~1367-1368 W/m^2).
  This is approximately +6-7 W/m^2 above the modern SI-traceable scale used by TIM.
