Welcome to the IASI Portal!
The IASI Portal provides scientists with free and open access to atmospheric composition Level 2 data products retrieved from the IASI/Metop observations along with quicklook images for several species:
- Level 2 data products
CO, O3, HCOOH, NH3, δD, SO2, DUST-AOD, CH4 & CLOUD
- Quicklook images
Daily and monthly maps can be viewed on the global and continental scale
How did ozone pollution evolve during the COVID-19 lockdown of spring 2020?
In the boreal spring of 2020, worldwide measures for curbing the spread of the COVID-19 virus have led to unprecedented and abrupt lockdowns in transportation and industry. They have led to sharp decrease of emissions of anthropogenic pollutants that induced significant changes in the composition of the atmosphere from city to hemispheric scale. Using an […]
Homogeneous temperature data record derived from 13 years of IASI data using an artificial neural network
Bouillon et al. (2022) recently designed a neural network to retrieve atmospheric temperatures from the IASI radiance data. This new temperature data record is validated against other datasets and a good agreement is shown. Trends were computed from this new temperature dataset over the 2008–2020 period. A general warming of the troposphere, more important at […]
Humidity levels to determine future liveability in the Arabian Peninsula
Human survivability in hot regions does not depend only on temperature, but also on humidity levels in ambient air. In fact, the body’s ability to shed heat is diminished when the air around it is saturated with humidity. The wet bulb temperature (also called heat stress) is the temperature of the air when it is […]
