Time evolution of temperature profiles retrieved from 13 years of infrared atmospheric sounding interferometer (IASI) data using an artificial neural network [PDF]

open access: yesAtmospheric Measurement Techniques, 2022
The three infrared atmospheric sounding interferometers (IASIs), launched in 2006, 2012, and 2018, are key instruments to weather forecasting, and most meteorological centres assimilate IASI nadir radiance data into atmospheric models to feed their ...

Bridging the spatial gaps of the Ammonia Monitoring Network using satellite ammonia measurements [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
Ammonia (NH3) is a key precursor to fine particulate matter (PM2.5) and a primary form of reactive nitrogen. The limited number of NH3 observations hinders the further understanding of its impacts on air quality, climate, and biodiversity. Currently, NH3

Smarandache mukti-squares [PDF]

open access: yes, 2007
We have introduced Smarandache quasigroups which are Smarandache non-associative structures. A quasigroup is a groupoid whose composition table is a Latin square.

Oxidation of low-molecular-weight organic compounds in cloud droplets: global impact on tropospheric oxidants [PDF]

open access: yesAtmospheric Chemistry and Physics, 2021
In liquid cloud droplets, superoxide anion (O2(aq)-) is known to quickly consume ozone (O3(aq)), which is relatively insoluble. The significance of this reaction as a tropospheric O3 sink is sensitive to the abundance of O2(aq)- and therefore to the ...

Global, regional and national trends of atmospheric ammonia derived from a decadal (2008–2018) satellite record

open access: yesEnvironmental Research Letters, 2021
Excess atmospheric ammonia (NH _3 ) leads to deleterious effects on biodiversity, ecosystems, air quality and health, and it is therefore essential to monitor its budget and temporal evolution.

Long-term trends in air quality in major cities in the UK and India: a view from space [PDF]

open access: yesAtmospheric Chemistry and Physics, 2021
Air quality networks in cities can be costly and inconsistent and typically monitor a few pollutants. Space-based instruments provide global coverage spanning more than a decade to determine trends in air quality, augmenting surface networks.
