The Cassini Synthetic Aperture Radar (SAR) has been acquiring images of Titan's surface since October 2004. Radar data suffer from speckle noise hindering interpretation of small-scale features and comparison of reimaged regions for topography derivation and potential detection. By combining a state of the art denoising algorithm with mapping and quantitative measurements we greatly offer previously unattainable insights and introducing the denoising version of the Cassini SAR named NLDSAR.The...
OPTICLEAF is a database of leaf optical properties. Maintained by Stéphane Jacquemoud.
3D Synthetic Seismogram Package is a set of libraries and programs for the computation of normal modes and seismograms for a wide variety of 3D Earth models. This code is based on the higher order perturbation theory in seismology developed by Philippe Lognonné, and requires only a few parameter settings. The codes runs successfully on several operating systems. Disk space of at least 1 GB and 600 MB of memory are recommended for practical use. The source code is contained in gzip/...
SHTOOLS is an archive of fortran 95 based software that can be used to perform spherical harmonic transforms and reconstructions, rotations of spherical harmonic coefficients, and multitaper spectral analyses on the sphere. While several collections of code currently exist for working with data expressed in spherical harmonics, this one is unique for several reasons: It can accommodate any standard normalization of the spherical harmonic functions ("geodesy" 4π normalized,...
