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。分析这些数据往往很耗时，减缓了将数据转化为科学见解的速度。该研究小组在美国国家科学基金会先前的资助下，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，有助于分析和可视化数据。该奖项将迈出下一步，使LRose在线可用，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。该项目将对利用激光雷达和雷达数据的所有科学领域产生影响，例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，为LROSS开发了一个功能齐全的科学门户。研究小组将把LROSE整合到网络门户环境中，从而允许通过网络浏览器界面随时访问计算资源，并允许用户在云中直接移动数据。CSSI元素奖的目的是促进分析和数据处理工具的使用，减少有效科学的障碍并扩大用户基础。该项目有两个主要的开发部分：1)底层基础设施，包括网关、数据处理层和数据可视化能力，以及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NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
