We describe a work in progress on the reconstruction of radial profiles for the ion effective charge Z eff on the TEXTOR tokamak, using statistical data analysis techniques. We introduce our diagnostic for the measurement of bremsstrahlung emissivity signals. Z eff profiles can be determined by Abel-inversion of line-integrated measurements of the bremsstrahlung emissivity (ǫ ff) from the plasm...

An approach to land surface temperature (LST) estimation that relies upon Bayesian inference has been validated against multiband infrared radiometric imagery from the Terra MODIS instrument. Bayesian LST estimators are shown to reproduce standard MODIS product LST values starting from a parsimoniously chosen (hence, uninformative) range of prior band emissivity knowledge. Two estimation method...

Context. The far-infrared (FIR) and sub-millimeter (submm) emissivity, ϵ ν , of the Milky Way (MW) cirrus is an important benchmark for dust grain models. Dust masses in other galaxies are generally derived from FIR/submm using emission properties these MW-calibrated Aims. We seek to derive nine nearby spiral check its compatibility with MW measurements. Methods. obtained values at 70–500 μm, m...
