CLARREO Pathfinder/VIIRS Intercalibration: Quantifying the Polarization Effects on Reflectance and the Intercalibration Uncertainty [PDF]
Remote Sensing, 2019 Atmospheric scattering and surface polarization affect radiance measurements of polarization-sensitive instruments on orbit. Neglecting the polarization effects may lead to an inaccurate radiance/reflectance determination and underestimated radiance ...

Three New Calcium Formate Reference Materials for δ<sup>13</sup>C Measurements and a Redetermination of the R(<sup>13</sup>C/<sup>12</sup>C) Ratio for VPDB Based on Proton Nuclear Magnetic Resonance Measurements. [PDF]
Rapid Commun Mass SpectromABSTRACT Rationale Isotope ratio mass spectrometry (IRMS) and proton nuclear magnetic resonance (1H NMR) spectroscopy are independent techniques for determining the isotope ratio R(13C/12C) in organic compounds. However, the lack of suitable reference materials has limited intercalibration of results from these methods.

Reaffirming the Consistency of the Original Stock of NBS 19 Limestone and Its Byproduct With Finer Grain Size for δ<sup>13</sup>C and δ<sup>18</sup>O Calibrations-Both Distributed Internationally. [PDF]
Rapid Commun Mass SpectromABSTRACT Rationale Approximately 3–4 kg of NBS 19 limestone, prepared in 1982 by the U.S. Geological Survey (USGS), serves as a primary reference for the carbon isotope scales VPDB and VPDB‐LSVEC and the oxygen isotope scale VPDB. Its consensus values are +1.95‰ for δ13C and −2.2‰ for δ18O measurements.
