DYNAmics of the Madden-Julian Oscillation (DYNAMO) Legacy Data Products

该奖项支持为在马登-朱利安振荡(发电机)野外运动的动态过程中收集的数据创建遗留数据集。迪纳摩的目标是观察马登-朱利安振荡(MJO)的起源。MJO是在印度洋形成的一种大规模降水和大气环流模式，向东缓慢传播，影响全球大部分地区的天气和气候。这场战役于2011年10月1日至2012年2月9日在印度洋举行，是一项涉及船只、飞机、探测系统和岛基雷达“超级站点”的大规模活动。几个美国机构和国际合作伙伴参与其中，如美国国家科学基金会奖AGS-1022899的摘要所述。这场运动是成功的，因为在部署期间发生了三次MJO事件，其中第一次发生在特别观察期，当时所有外地资产都部署在一起。总共收集了大约10太兆字节的数据。鉴于运动的成功和对运动的大量投资，有必要进一步投资，以加强运动数据的可获取性，并促进研究界使用这些数据。将根据用于收集观测的仪器类型开发三类数据产品：基于雷达的产品、基于飞机的产品和基于探测的产品。第四类是以符合研究界具体兴趣的方式处理的数据产品，例如，将探空数据处理成可降水量、对流可用势能、对流抑制、提升凝结水平和自由对流水平等变量。整个收集将由国家大气研究中心的地球观测实验室主持。这个项目有点不寻常，因为它的目标是为研究界开发和服务数据集，而不是为了解决科学假说而进行研究。因此，所有这些努力都可以被视为对研究界的更广泛影响。还应该指出的是，MJO具有许多社会后果，因为它是热带天气的主要驱动因素，也对美国产生影响。在其他影响中，MJO影响了墨西哥湾形成的飓风数量。因此，研究如何在天气预报模式中更好地表示MJO是可取的。此外，这些数据产品将促进对热带对流的总体研究，这将对开发更好的预报天气和预测未来气候变化的模式具有价值。

This award supports the creation of a legacy dataset for data collected during the DYNAmics of the Madden-julian Oscillation (DYNAMO) field campaign. The goal of DYNAMO was to observe the initiation of the Madden-Julian Oscillation (MJO). The MJO is a large-scale pattern of precipitation and atmospheric circulation that forms in the Indian Ocean and propagates slowly eastward affecting weather and climate across a large portion of the globe. The campaign took place in the Indian Ocean from 1 October 2011 until 9 February 2012 and was a massive undertaking involving ships, aircraft, sounding systems, and an island-based radar "supersite". Several US agencies and international partners were involved, as documented in the abstract for NSF award AGS-1022899. The campaign was a success in that three MJO events occurred during the deployment, of which the first occurred during the Special Observing Period when all the field assets were deployed together. Overall about 10 terabytes of data were collected.Given the success of the campaign and the large investments made in it, a further investment is warranted to enhance the accessibility of the campaign data and facilitate its used by the research community. Three categories of data products will be developed on this award, characterized by the type of instrumentation used to collect the observations: radar-based, aircraft-based, and sounding-based products. A fourth category consists of data products processed in ways consistent with specific interests of the research community, for instance sounding data processed into variables like precipitable water, convective available potential energy, convective inhibition, lifting condensation level, and the level of free convection. The entire collection will be hosted by the Earth Observing Laboratory at the National Center for Atmospheric Research.This project is somewhat unusual in that the goal is to develop and serve a dataset for the research community, rather than to conducted research to address a scientific hypothesis. Thus all of the effort can be regarded as a broader impact to the research community. It should also be noted that the MJO has a number of societal consequences, as it is a dominant driver of weather in the tropics and also affects on the US. Among other impacts, the MJO influences the number of hurricanes that form in the Gulf of Mexico. Research leading to better representation of the MJO in weather forecasting models is thus desirable. In addition, the data products will facilitate research on tropical convection in general, which will be of value for developing better models to predict weather and make projections of future climate change.
