•We have modeled the lunar argon (40Ar) exosphere as constrained by Apollo 17 LACE measurements.•The trapping in the PSRs is a sink for 40Ar comparable to both photo-ionization and charge-exchange with solar protons.•The density of 40Ar measured by LACE appears to have originated from no less than f...
