An overview of MATISSE-v2.0

Development and validation of a numerical tool for simulating the surface temperature field and the infrared radiance rendering in an urban scene

“…• MOHICANS is finally used to get the spectral infrared radiance incident to the sensor from the temperature field computed by SUSHI and from the atmosphere radiative parameters computed by MATISSE [25].…”

“…It is actually a fusion of two previously developed codes: AMARTIS [28] for the visible to near infrared range and TITAN [27] for the midwave to longwave infrared range. Both of them rely on atmospheric radiative contributions which are computed by the ONERA code MATISSE [25]. The spectral domain finally covers the 0.4 to 14 µm range.…”

“…A radiative transfer code is required to simulate the multiple reflections between the surfaces of the scene and the atmosphere contributions. Atmospheric radiative transfer codes like Modtran [24] and MATISSE [25] are based on the radiative transfer equation and can calculate the spectral contributions of the atmosphere along the line of sight (transmission, self-emission, molecular/aerosol scattering…). They are however limited to a simplified geometry (plane or spherical ground).…”

Multiresolution infrared optical properties for Gaussian sea surfaces computations: comparison against the MIRAMER campaign measurements in solar glint configurations

“…If the ray intercept a clipmap facet F associated to the biome "sea", the sea radiance L sea (F, − → u o ) coming from F in − → u o direction is estimated. Evaluation of the other contributors to the sensor coming irradiance is detailed in Labarre et al 9 The directional sea radiance is composed of the sea radiative emission, the reflected radiance of the sun and the sky, and the up-welling radiance from within the sea, resulting from sunlight and skylight which has been transmitted downward through the air-water interface, scattered upward by the deep water and transmitted through the water-air interface toward the sensor. [10][11][12] The skin thickness, or skin depth, is the distance of penetration within which the current density is reduced to 1/e of its magnitude at the surface.…”

A new lidar inversion method using a surface reference target applied to the backscattering coefficient and lidar ratio retrievals of a fog-oil plume at short range

“…It depends on the wavelength (in vacuum) and the microphysics, morphology and size of the particles (Hoff et al, 2008). The LR ranges from 20 to 100 sr at 532 nm (Ackermann, 1998;Cattrall et al, 2005;Leblanc et al, 2005) according to the aerosol origins (maritime, urban, dust particles and biomass burning). It is therefore difficult to assume an a priori value for LR inasmuch as this information is to be found rather than given.…”
