International Research Fellowship Program: The Role of Advection on CO2 Flux Measurements at the Cabauw Tall Tower, the Netherlands

国际研究奖学金计划使美国科学家和工程师能够在国外进行三到二十四个月的研究。该计划的奖项提供了联合研究的机会，并利用国外独特或互补的设施、专业知识和实验条件。该奖项将支持辛西娅·A·沃纳博士与荷兰德比尔特荷兰皇家气象研究所的弗雷德·博斯维尔德博士合作十个月的研究奖学金。该项目将通过测量荷兰卡博气象塔来评估二氧化碳通量。这项实验应该会对二氧化碳通量测量和平流二氧化碳通量的误差产生第一个现实的估计。卡博遗址提供了一个独特的机会，因为它的高度和缺乏地表的异质性。Werner博士将建立平流通量的基准值，该值将确定位于更复杂地形的站点由于平流分量所能预期的最小误差量。这一基准值特别重要，因为只有少数站点有能力评估平流分量网，而且通常只有在预计会出现很大误差的情况下才会进行评估。收集的数据将补充欧洲其他研究碳循环和全球气候变化的研究。除了与博斯维尔德博士合作外，PI还将与海洋与大气研究所(IMAU)的Peter Duynkerke博士、荷兰能源研究中心(ECN)的Alex Vermeulen博士合作。

0202636WernerThe International Research Fellowship Program enables U.S. scientists and engineers to conduct three to twenty-four months of research abroad. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad.This award will support a ten month research fellowship by Dr. Cynthia A. Werner to work with Dr. Fred Bosveld at the Royal Netherland Meteorological Institute in De Bilt, The Netherlands.This project will evaluate the CO2 fluxes by instrumenting the Cabauw meteorological tower in the Netherlands. This experiment should yield the first realistic estimates of the errors in CO2 flux measurement and in advective CO2 flux. The Cabauw site affords a unique opportunity because of its height and lack of surface heterogeneity. Dr. Werner will establish a baseline value for advective flux which will determine the minimal amount of error that sites located in more complicated terrain can expect due to the advective component. This baseline value is particularly significant because only a few sites have the ability to assess the advective componenet and typically this is performed only when very large errors are expected. The data collected will complement research done by others studying the carbon cycle and global climate change across Europe.In addition to working with Dr. Bosveld, who is in charge of all measurements made at Cabauw, the PI will also work with Dr. Peter Duynkerke of the Institute for Marine and Atmospheric Research (IMAU), Dr. Alex Vermeulen of the Energy Research center of the Netherlands (ECN).
