FORUM and IASI-NG pseudo-observations

The Earth Explorer 9 Far-infrared Outgoing Radiation Understanding and Monitoring (FORUM) mission will bring the first satellite instrument capable of observing the Earth's far infrared (FIR) spectra with a high spectral resolution. Using an ad-hoc pseudo-observations (PO) simulator, we generate FORUM PO that we use to evaluate its sensitivity to dust aerosols. Different dust scenarios are tested, in terms of mineralogy, source region and background atmosphere, burden and vertical distribution. To compare the sensitivity of the FIR (15–100 µm) part of the spectra to that of the mid infrared (MIR, 2.5–15 µm) as observed e.g. by the Infrared Atmospheric Sounder Interferometer – New Generation (IASI-NG) instrument, we also generated IASI-NG PO for the same scenarios.

Please refer to the README file for more details on the different scenarios in this PO dataset.
