abstract = {This paper presents a new dataset of nighttime atomic
oxygen density [O], derived from OH(8–4) ro-vibrational
band emissions, using a non-local thermal equilibrium model,
with the aim of offering new insight into the atomic oxygen
abundances in the mesopause region. The dataset is derived
from the level-1 atmospheric background measurements
observed by the Global Ozone Monitoring by Occultation of
Stars (GOMOS) instrument aboard Envisat, with the Sounding
of the Atmosphere using Broadband Emission Radiometry
(SABER) measurements for the atmospheric background. Raw
data are reprocessed into monthly zonal mean values in 10∘
latitude bins with a fixed altitude grid of 3 km. The
dataset spans from 70∘ S to 70∘ N in latitude and
from 80 to 100 km in altitude, covering a time period from
May 2002 to December 2011 at local times from 22:00 to
00:00 LT.The atomic oxygen density peaks at about 95 km
and the highest values are in the range of
3–8 × 1011 atoms cm−3, depending on latitude
and season. There is a rapid decrease of [O] below the peak.
The annual oscillation (AO), semiannual oscillation (SAO)
and the solar cycle impact are distinguished from the [O]
longtime series variations. This new GOMOS [O] dataset
conforms to other published datasets and is consistent with
the [O] datasets obtained from the Scanning Imaging
Absorption Spectrometer for Atmospheric CHartographY
(SCIAMACHY) OH airglow measurements within about
$±20 \%.$},
