# # Data product developed by Dr. E.

Thiemann (thiemann@lasp.colorado.edu) and # to the LYRA Principal Investigator M. Dominique (marie.dominique@oma.be) # # PROBA2 data products are open to all. # Users should however refer to the following paper: http://arxiv.org/abs/1708.08833 # and acknowledge the instrument according to the rules described # at http://proba2.oma.be/data/termsOfUse in their papers and presentations # # Website reference http://proba2.oma.be/lyra/data/EarthAtmosphere/ # # Description: # Summed neutral N2 and O number density profiles, spanning altitudes between 150 and 400 km # retrieved from LYRA data acquired during occultations by the unit 3 (backup unit) zirconium # channel (bandpass: 1-2 nm + 6-20 nm). # # Radial distance is the distance from the center of Earth expressed in km to which the density corresponds. # Density O-N2 provides the summed number density of neutral O and N2 in units of radial distance and cm^-3. # The systematic error is a signed value (asymmetric) in fractional units and is primarily from the error made by # assuming that the absorption cross-sections of O and N2 are equal; a secondary source of systematic error is # from using a single-scale height atmosphere in the reference atmosphere used by the retrieval algorithm. # The random error is an unsigned value (to be applied symmetrically to the measurement) in fractional # units and gathers the uncertainties from solar spectra, solar variability and measurement noise. # Both uncertainties are described in http://arxiv.org/abs/1708.08833. # The Longitude and Latitude (in degrees) columns refer to the tangential point along the # line-of-sight, where most of the absorption occurs. # # Scale height = 55.155203 km # Date (UTC) = 2013-12-02T10:40:33.046 # Date (julian) = 2456628.94482692 # # Radial distance Density O-N2 Systematic error Random error Longitude Latitude
