    Abstract
    An analysis has been made of the calibrations done during 1990 through 1994 on Rotronic MP- 100 relative humidity sensors (used in the Improved METeorological (IMET) system and sensors built at the Woods Hole Oceanographic Institution (WHOI) with the Vaisala Humicap sensing element (used in the Vector Averaging Wind Recorder (VAWR)). The shift from one calibration to the next is, typically, 2-3% RH which represents the major uncertainty in relative humidity with either of these sensors. The direction of each shift appears to be random; thus, there does not appear to be any long-term drifts.

      A recently published radiocarbon calibration curve extending to 50,000 cal BP (Fairbanks et al. 2005) is purportedly superior to that generated by the IntCal working group beyond the end of the tree-ring data at 12,400 ...

      Sr/Ca ratios recorded in the aragonite skeleton of massive coral colonies are commonly used to reconstruct seasonal‐ to centennial‐scale variability in sea surface temperature (SST). While the Sr/Ca paleothermometer is ...
