CDAWeb

The CDAWeb data system enables improved display and coordinated analysis of multi-instrument, multimission data bases of the kind whose analysis is critical to meeting the science objectives of the ISTP program and the InterAgency Consultative Group (IACG) Solar-Terrestrial Science Initiative. The system combines the client-server user interface technology of the World Wide Web with a powerful set of customized IDL routines to leverage the data format standards (CDF) and guidelines for implementation adopted by ISTP and the IACG. The system can be used with any collection of data granules following the extended set of ISTP/IACG standards. CDAWeb is being used both to support coordinated analysis of public and proprietary data and better functional access to specific public data such as the ISTP-precursor CDAW 9 data base that is formatted to the ISTP/IACG standards. Many data sets are available through the Coordinated Data Analysis Web (CDAWeb) service and the data coverage continues to grow. These are largely, but not exclusively, magnetospheric data and nearby solar wind data of the ISTP era (1992-present) at time resolutions of approximately a minute. The CDAWeb service provides graphical browsing, data subsetting, screen listings, file creations and downloads (ASCII or CDF). Public data from current (1992-present) space physics missions (including Cluster, IMAGE, ISTP, FAST, IMP-8, SAMPEX and others). Public data from missions before 1992 (including IMP-8, ISIS1/2, Alouette2, Hawkeye and others). Public data from all current and past space physics missions. CDAWeb ist part of "Space Physics Data Facility" (https://www.re3data.org/repository/r3d100010168).

CDAWeb数据系统旨在提升多仪器、多任务数据集的展示与协同分析能力，此类数据的分析对于满足ISTP项目及星际咨询组（IACG）太阳-地球科学倡议的科学目标至关重要。该系统融合了万维网客户端-服务器用户界面技术与一套强大的定制IDL例程，以利用ISTP与IACG所采纳的数据格式标准（CDF）及实施指南。系统适用于遵循ISTP/IACG扩展标准的任何数据粒度集合。CDAWeb不仅被用于支持公共与专有数据的协同分析，还优化了对特定公共数据（如格式化为ISTP/IACG标准的ISTP-先驱CDAW 9数据库）的访问功能。通过协调数据分析网络（CDAWeb）服务，众多数据集得以提供，且数据覆盖范围持续扩大。这些数据集主要（但不限于）包括ISTP时代（1992年至今）的磁层数据及邻近太阳风数据，时间分辨率约为每分钟一次。CDAWeb服务提供图形浏览、数据子集、屏幕列表、文件创建与下载（ASCII或CDF）等功能。公共数据包括当前（1992年至今）的空间物理任务数据（包括Cluster、IMAGE、ISTP、FAST、IMP-8、SAMPEX等）以及1992年之前任务的数据（包括IMP-8、ISIS1/2、Alouette2、Hawkeye等）。CDAWeb是“空间物理数据设施”的一部分（https://www.re3data.org/repository/r3d100010168）。
