Remote sensing observations from weather radars and lidars consist of a tremendous amount of raw data. Analysis of this data is often time-consuming, slowing the translation of data to scientific insights. The research team, under prior NSF funding, developed the Lidar Radar Open Software Environment (LROSE) which consists of freely available tools to help analyze and visualize data. This award will take the next step by making LROSE available online, eliminating the need for a complicated installation on local computers and taking advantage of data sets on the cloud. The impact of this project will be on all areas of science that make use of lidar and radar data, such as for severe weather and air quality. The online approach will also make it possible for educators to set up exercises and teaching aids for students in a classroom, along with the relevant data and documentation for learning activities.This project builds upon the Lidar Radar Open Software Environment, which is a software toolbox for analyzing radar and lidar data, by developing a fully functional science gateway for LROSE. The research team will integrate LROSE into a web portal environment, thereby allowing ready accessibility to computational resources via web browser interfaces and allowing users to move data directly within the cloud. The intent of this CSSI Elements award is to facilitate access to analysis and data processing tools, reducing barriers to effective science and expanding the user base. The project has two major development components: 1) the underlying infrastructure, including the gateway, the data handling layer and data visualization capabilities, and 2) the scientific software modules that allow users to perform experiments using the data.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

气象雷达和激光雷达的遥感观测包含了大量的原始数据。对这些数据的分析通常很耗时，减慢了将数据转化为科学见解的速度。在NSF的资助下，该研究团队开发了激光雷达开放软件环境（LROSE），该环境由免费提供的工具组成，以帮助分析和可视化数据。该合同将采取下一步措施，使LROSE可以在线使用，消除在本地计算机上复杂安装的需要，并利用云上的数据集。这个项目将对所有利用激光雷达和雷达数据的科学领域产生影响，比如恶劣天气和空气质量。在线方法还将使教育工作者能够在课堂上为学生设置练习和教学辅助工具，以及学习活动的相关数据和文件。该项目建立在激光雷达开放软件环境的基础上，这是一个分析雷达和激光雷达数据的软件工具箱，通过为LROSE开发一个功能齐全的科学网关。研究小组将把LROSE集成到web门户环境中，从而允许通过web浏览器接口随时访问计算资源，并允许用户直接在云中移动数据。此次CSSI元素奖的目的是促进对分析和数据处理工具的访问，减少有效科学研究的障碍，扩大用户基础。该项目有两个主要的开发组件：1)底层基础设施，包括网关、数据处理层和数据可视化功能；2)允许用户使用数据进行实验的科学软件模块。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
