“Testing and Development of Transfer Functions for Weighing Precipitation Gauges in WMO-SPICE”, by John Kochendorfer, Rodica Nitu, Mareile Wolff, Eva Mekis, Roy Rasmussen, Bruce Baker, Michael E. Earle, Audrey Reverdin, Kai Wong, Craig D. Smith, Daqing Yang, Yves-Alain Roulet, Tilden Meyers, Samuel Buisan, Ketil Isaksen, Ragnar Brækkan, Scott Landolt, and Al Jachcik was accepted for publication in Hydrology and Earth Systems Sciences. The publication describes how, due to the effects of wind, precipitation gauges typically underestimate the amount of precipitation that occurs as snow. Measurements recorded during a World Meteorological Organization intercomparison of precipitation gauges were used to evaluate and improve the adjustments that are available to address this issue. Adjustments for specific types of precipitation gauges and wind shields were tested and recommended.
Scientists from ARL (HQ and ATDD) and ESRL met in Boulder, Colorado, January 17-18, 2018 for a collaborative strategy session. There were three primary goals for this meeting: to exchange information on current air chemistry research at ARL/ESRL; to discuss short-term and long-term plans to utilize air chemistry research to support NOAA core missions and educate OAR management about the importance of air chemistry research to NOAA’s missions; and to explore potential opportunities for collaboration (i.e. joint projects, proposals, interactions with OAR programs). Following the presentation of lab overviews to the entire group, participants divided into three subgroups to participate in concurrent sessions related to their respective areas of specialty – air chemistry, dispersion, and Climate Reference Network/boundary layer processes. Each of the three topic areas had its own full agenda, complete with a lengthy slate of five-minute “lightning talks” on projects, personal interests, and suggested collaborations, followed by more in-depth, focused discussions. The entire group then reconvened Thursday afternoon to hear a summary of each working group’s interactions, and to discuss strategies and next steps.
