AmeriFlux Annual Meeting 2021
Praveena Krishnan and Tilden Meyers attended Ameriflux annual meeting held virtually during September 20-22, 2021. The theme of the meeting was ‘Reflect | Connect: AmeriFlux in 2021’. The sessions focused on water fluxes, natural climate solutions, and other open science questions, while many breakout rooms discussed different raising topics in flux and science communities.
How Well are We Measuring Snow Post-SPICE? Accurate snowfall measurements are necessary for meteorology, hydrology, and climate research. Typical uses include creating and calibrating gridded precipitation products, the verification of model simulations, driving hydrologic models, input into aircraft deicing processes, and estimating streamflow runoff in the spring. These applications are significantly impacted by errors in solid precipitation measurements. The recent WMO Solid Precipitation Intercomparison Experiment (SPICE) attempted to characterize and reduce some of the measurement uncertainties through an international effort involving 15 countries utilizing over 20 types and models of precipitation gauges from various manufacturers. Key results from WMO-SPICE are presented herein. Recent work and future research opportunities that build on the results of WMO-SPICE are also highlighted.
