pynusinov

pyNusinov package provides Python3 implementations of Solar (ultraviolet) irradiance models developed under supervision of Professor, Dr. Anatoly Abramovich Nusinov.

The following models are provided:

• EUVT2021, 5-105 nm, 20 bands + 16 lines, [Nusinvov et al., 2021]
• FUVT2021, 115-242 nm, 127 bands, [Nusinvov et al., 2021]
• FUVT2019, 115-242 nm, 127 bands, [Nusinvov et al., 2019]
• EUVN1992, 10-105 nm, 19 bands + 16 lines, [Nusinvov et al., 1992]
• XUVN1992, 0.1-10 nm, 13 bands, [Nusinvov et al., 1992]
• EUVN1984, 10-105 nm, 19 bands + 16 lines, [Nusinvov et al., 1984]
