Snow‐Covered Insights From Above and Below: High‐Frequency Measurement of Nitrogen Dioxide From Space and Ground

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The Tropospheric Emissions: Monitoring of Pollution (TEMPO) satellite provides hourly air quality measurements over North America. This study evaluates TEMPO NO2 ${\text{NO}}_{2}$ observations over snow‐covered surfaces, highlighting its ability to capture sharp spatial and temporal gradients in NO2 ${\text{NO}}_{2}$ vertical column densities ...

Reduced central alpha power at rest is associated with the risk of alcohol‐induced blackout and frequency of non‐REM parasomnia episodes in adults

Physiological Reports, Volume 14, Issue 6, March 2026.
Abstract People who experience alcohol‐induced blackouts (AIBs) are at increased risk of alcohol‐related injury and even death. Blackout susceptibility is heritable and blackouts are not experienced by all who engage in hazardous drinking. Blackout is defined by amnesia, but a person in the blackout state also maintains consciousness and motor control ...

Ground-based FTIR and MAX-DOAS observations of formaldehyde at Réunion Island and comparisons with satellite and model data [PDF]

Atmospheric Chemistry and Physics, 2009
Formaldehyde (HCHO) columns have been retrieved from ground-based Fourier transform infrared (FTIR) campaign measurements in 2004 and 2007 and from UV-Visible MAX-DOAS measurements in 2004–2005 at the NDACC site of Réunion Island (21° S, 55& ...

MAX-DOAS detection of glyoxal during ICARTT 2004

Atmospheric Chemistry and Physics, 2007
The direct detection of glyoxal (CHOCHO), the smallest α-dicarbonyl, in the open atmosphere by active differential optical absorption spectroscopy (DOAS) has recently been demonstrated (Volkamer et al., 2005a) and triggered the very recent successful detection of CHOCHO from space (Kurosu et al., 2005; Wittrock et al., 2006; Beirle et al., 2006).

Intercomparison of slant column measurements of NO2 by ground-based MAX-DOAS

Acta Physica Sinica, 2013
In September 2011, we used 3 ground-based multi-axis differential optical absorption spectroscopy (MAX-DOAS) instruments of different designs and operation protocols to measure tropospheric NO2 for about 20 days, at the Station of Atmospheric Comprehensive Observatory, Institute of Atmospheric Physics, Chinese Academy of Sciences (Xianghe 117.0N, 39 ...

First retrieval of tropospheric aerosol profiles using MAX-DOAS and comparison with lidar and sky radiometer measurements [PDF]

Atmospheric Chemistry and Physics, 2008
Ground-based Multi-Axis Differential Optical Absorption Spectroscopy (MAX-DOAS) measurements were performed at Tsukuba, Japan (36.1° N, 140.1° E), in November–December 2006.
