Project Description

Specification, prototyping and scientific validation of IASI-NG processing suite

The mission allows the monitoring greenhouse gases, clouds, aerosols, ozone and trace gases.

The main objective of IASI-NG is to provide observations of the atmosphere for the weather prediction. The instrument measures infrared radiance spectra. The mission will allow the monitoring greenhouse gases, clouds, aerosols, ozone and trace gases. Due its high level on spectral calibration accuracy, IASI-NG will also be crucial for climate activities.

The mission will allow the monitoring greenhouse gases, clouds, aerosols, ozone and trace gases. Due its high level on spectral calibration accuracy, IASI-NG will also be crucial for climate activities.
The IASI-NG mission develop a new instrument concept based on Mertz interferometer for which the field is compensated. The on-ground processing is specified with new algorithms such as “spikes” correction and the equalization of spectra. New algorithm suites are also being elaborated to estimate the instrument function in real time by using measured atmospheric spectra and instrument observables.

Means used

NOVELTIS supports CNES in the elaboration and validation of the system performance simulator of IASI-NG mission:

  • Prototyping and validation of the instrument response function estimation model of the IASI-NG interferometer
  • Prototyping and validation of the IASI-NG on-ground imager processing chain
  • Validation of the level 1 processing of the sounder
  • Monitoring and estimation of the spectral shift delivered to the spectral response function estimation model

Results

A new methodology has been prototyped and validated for the spectral shift estimation on earth view spectra. The prototype for the instrument spectral response function estimation has been developed. All the algorithms involved in the on-ground processing of the system performance simulator have also been validated.
