Atmospheric composition data products

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:

  1. Level 2 data products
    CO, O3, HCOOH, NH3, δD, SO2, DUST-AOD, CH4 & CLOUD
  2. Quicklook images
    Daily and monthly maps can be viewed on the global and continental scale

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 […]

Trends in spectrally resolved outgoing longwave radiation from 10 years of satellite measurements

By analyzing the changes in the spectrally resolved Earth’s Outgoing Longwave Radiation (OLR) from 10 years of daily IASI observations, Whitburn et al. (2021) have highlighted the impact of large climate phenomena (in particular El Niño) on the surface and atmospheric temperature and atmospheric composition. More interesting from a longer-term climate monitoring perspective, they were […]
