Comments: The NO3 absorption cross section at 662 nm was (2.23 ± 0.22) x 10^-17 cm2 at 298 K and increased 36%
in going from 298 to 200 K.
sigma (662 nm) 298K: (2.23 ± 0.22) x 10^-17
sigma (662 nm) 258K: (2.49 ± 0.13) x 10^-17
sigma (662 nm) 230K: (2.76 ± 0.13) x 10^-17
sigma (662 nm) 200K: (2.99 ± 0.14) x 10^-17
