Software and Models

This page provides links to models and software, of relevance to field spectroscopy, that are hosted on the FSF website. Please note that whilst the FSF is pleased to make these programs available to the field spectroscopy community we are not able to provide individual support to software users.

Microtops Inverse (Tsanev, V.I. and Mather, T.A., 2007) is a software package designed to allow the retrieval, from Microtops II measurements, of columnar optical thickness of aerosols concentrated in plumes (from volcanoes, fires or industrial plants). For further information or to download the software packages click here.

LIBERTY (Leaf Incorporating Biochemistry Exhibiting Reflectance and Transmittance Yields) is a radiative transfer model developed by Dawson et al., (1998) to simulate coniferous needle optical properties. LIBERTY allows prediction of the reflectance and transmittance spectra of a coniferous needle, or stack of coniferous needles, in the visible and near infrared wavelengths (400 - 2500 nm).

Planarrad is a freely available open-source C++ implementation of the invariant imbedded numerical integration technique for calculating radiative transfer in plane-parallel shallow-water environments, i.e. where the substrate reflectance and water column optical properties can be assumed horizontally homogenous. A report summarising the results obtained during the field demonstration of the NERC FSF aquatic optical sampling equipment at RSPSoc 2008 is now available to download here. Planarrad is now available. For more information please click here .

WLTool is a freely available open-source C++ software program for extracting and merging data from WETLabs DH4 data logger archive files. WLTool was designed to work specifically with the FSF aquatic instrumentation suite and allows instant visualisation of archive file data and facilates integration and merging of the HyperOCR irradiance and radiance sensors with the IOP instrument data. The output file format from WLTool can be read directly into Planarrad for ease of use. For more information about WLTool please click here
