MATISSE-v2.0: new functionalities and comparison with MODIS satellite images

Abstract

MATISSE (Advanced Modeling of the Earth for Environment and Scenes Simulation) is an infrared background scene generator developed for computing natural background spectral radiance images. The code also provides atmospheric radiatives quantities along lines of sight. Spectral bandwidth ranges from 0.4 to 14 μm. Natural backgrounds include atmosphere, sea, land and high and low altitude clouds. The new version MATISSE-v2.0, released this year, has been designed to treat spatial multi resolution in the generated images in order to be able to reach metric spatial variability in pixels footprints. Moreover, MATISSE-v2.0 includes a new sea surface radiance model (water waves and surface optical properties) which depends on wind speed, wind direction and fetch value. Preliminary validations using radiometric measurements have been conducted concerning sea radiances and give promising results. In order to go further in the validation process of MATISSE-v2.0, comparisons with MODIS satellite images have been led. The results of comparing the simulated MATISSE images radiances with the MODIS observations show that the code is performing well. This paper gives a description of MATISSE-v2.0 new functionalities and focus on first results on comparison between MATISSE/MODIS images radiances.

Reassessment of the temperature-emissivity separation from multispectral thermal infrared data: Introducing the impact of vegetation canopy by simulating the cavity effect with the SAIL-Thermique model

“…We used the same emissivity spectra as selected when computing the emission component. We simulated the spectra of atmospheric downwelling irradiance using the MATISSE-V2 (Acronym for French label meaning "earth advance modeling for imagery and simulation of scenes and their environments") atmospheric radiative transfer model (Labarre et al, 2010;Labarre et al, 2011). We used atmospheric profiles from the Air Force Research Laboratory (AFRL) dataset (Simoneau et al, 2006) as inputs for MATISSE-V2.…”

Development of an atmospheric infrared radiation model with high clouds for target detection

“…CERAMIC package has been validated in 1D for the average contributors, the average total radiance and the transmittance by MATISSE code. It is a referency code in 1D, which has been validated code to code with MODTRAN4, and by comparison with MODIS images [11] [16]. The 3D fluctuations model for the multiple scattering has been compared to SHDOM outputs, 3D referency code which can accuracy computes 3D radiances.…”

“…In addition, LUCI is coupled with six atmospheric profiles from AFRL [7]. The molecular optical properties are taken from MATISSE database [11]. The spectral bandwidth goes from 3330 to 3850 cm-1.…”

“…The 1D spectral validation is based on a comparison with MATISSE, standing for the Advanced Earth Modelisation for Imagery and Scene Simulation. Developped at ONERA, it provides radiance images including atmospheric emission and scattering, cloud scattering, ground reflexion and emission, atmospheric variability, using a Line-by-line (LBL) method and a K distribution method for solving IR radiative transfer [11].…”

“…The French Aerospace lab ONERA has been collaborating with the Fraunhofer IOSB in the development of a radiative transfer model for few years. Next to maritime environment [20], MATISSE has already been validated for space-based observations [11] [21] as well as specific homogenous cloud models [16] [22]. As mentioned before, a need has been expressed for the use of heterogeneous clouds in the model.…”
