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.

该奖项支持创建一个传统数据集，用于在Madden-Julian振荡（Dynamo）现场活动的动力学期间收集的数据。 Dynamo的目的是观察Madden-Julian振荡（MJO）的启动。 MJO是一种大规模的降水和大气循环模式，在印度洋形成，并缓慢地向东繁殖，影响全球大部分地区的天气和气候。 该活动发生在印度洋，从2011年10月1日至2012年2月9日，是一项涉及船只，飞机，响声系统和基于岛屿的雷达“超级站点”的巨大事业。 正如NSF Award AGS-1022899的摘要中所记录的那样，美国几个美国机构和国际合作伙伴参与其中。 该活动的成功是在部署期间发生了三个MJO事件，其中首次发生在所有现场资产一起部署的特殊观察期间。总体而言，收集了大约10个数据的数据。启动了竞选的成功和对其进行的大量投资，需要进一步的投资，以增强广告系列数据的可访问性并促进研究界使用的投资。 该奖项将开发三类数据产品，其特征是用于收集观测值的仪器类型：基于雷达，基于飞机和基于声音的产品。 第四类包括以与研究界的特定兴趣相一致的方式处理的数据产品，例如，将数据加工成诸如可沉淀水，对流势能，对流抑制，提升凝结水平以及自由对流水平等变量。 整个收藏集将由地球观察实验室在国家大气研究中心举办。该项目在某种程度上是不寻常的，因为目标是为研究界开发和服务数据集，而不是进行研究以解决科学假设。因此，所有的努力都可以视为对研究界的更广泛的影响。还应注意的是，MJO有许多社会后果，因为它是热带天气的主要驱动力，并且也影响了美国。 除其他影响外，MJO会影响墨西哥湾形成的飓风数量。因此，希望在天气预报模型中更好地代表MJO。此外，数据产品总体上将促进有关热带对流的研究，这对于开发更好的模型来预测天气并预测未来气候变化将是有价值的。
