[1] The electronic spin and valence states of Fe in post‐ perovskite ((Mg 0.75 Fe 0.25)SiO 3) have been investigated by synchrotron X‐ray diffraction, Mössbauer and X‐ray emission spectroscopy at 142 GPa and 300 K. Rietveld refinement of the X‐ray diffraction patterns revealed that our sample was dominated by CaIrO 3 ‐type post‐perovskite. Combined(More)
abstraCt Ferromagnesite [(Mg,Fe)CO 3 ] has been proposed as a candidate host mineral for carbon in the Earth's mantle. Studying its physical and chemical properties at relevant pressures and temperatures helps our understanding of deep-carbon storage in the planet's interior and on its surface. Here we have studied high-pressure vibrational and elastic(More)
Biogeosciences Discussions This discussion paper is/has been under review for the journal Biogeosciences (BG). Please refer to the corresponding final paper in BG if available. Abstract Networks that merge and harmonise eddy-covariance measurements from many different parts of the world have become an important observational resource for ecosystem science.(More)
A method for separating bare soil and foliage component temperatures in a pixel is presented which exploits the ATSR-2 multispectral and dual angle view capability. In this study, we develop first a method using visible and near infrared channel data at two-angle views to perform atmospheric corrections in these channels allowing simultaneous retrieval of(More)
