O2 continuum: A possible explanation for the discrepancies between measured and modeled shortwave surface irradiances
Abstract
Ground based solar spectra between 1 and 5µm (10,000 and 2000 cm-1) have been obtained with a new, absolutely calibrated spectrometer. These spectra have sufficient spectral resolution (2 cm-1) to allow atmospheric absorption lines to be distinguished from underlying continuum absorption. Continuum absorption due to O2 has been identified around 1.06µm (9366 cm-1), 1.27µm (7882 cm-1), and 1.6µm (6326 cm-1). These continuum absorptions are not included in the HITRAN database. Similar continuum absorption should be present around the 0.762µm (13121 cm-1) and 0.688µm (14525 cm-1) bands of O2.
