The solar argon abundance cannot be directly derived by spectroscopic observations of the solar photosphere. The solar argon abundance is evaluated from solar wind measurements, nucleosynthetic arguments, observations of B stars, H II regions, planetary nebulae, and noble gas abundances measured in Jupiter's atmosphere. These data lead to a recommended argon abundance of N (Ar) = 91,200 ± 23,700 (on a scale where Si = 10 6 atoms). The recommended abundance for the solar photosphere [on a scale where log N(H) = 12] is A (Ar) photo = 6.50 ± 0.10, and taking element settling into account, the solar system (protosolar) abundance is A (Ar) solsys = 6.57 ± 0.10.
