A new quality assessment report from NASA’s Commercial Satellite Data Acquisition ( CSDA ) program approves the use of precipitation radar data from Tomorrow.io for NASA scientific use.
NASA 商业卫星数据采集 (CSDA) 计划的一份新质量评估报告批准使用来自 Tomorrow.io 的降水雷达数据供 NASA 科学使用。
Issued March 9, 2026, the Commercial Satellite Data Acquisition Program Tomorrow.io Radar Quality Assessment Report documents the evaluation process of the NASA subject matter experts (SMEs) enlisted to analyze the data quality of the Ka-band Precipitation Radars aboard the company’s R1 and R2 spacecraft.
商业卫星数据采集计划 Tomorrow.io 雷达质量评估报告于 2026 年 3 月 9 日发布，记录了 NASA 主题专家 (SME) 受邀分析该公司 R1 和 R2 航天器上 Ka 波段降水雷达数据质量的评估过程。
The SMEs assessed the company’s Level 2 Precipitation products and geolocation accuracy and their results were generally in agreement with the analysis provided by Tomorrow.io in its algorithm theoretical basis document. The geolocation assessment showed “excellent correlation” of 0.98 with a digital elevation model (DEM) reference. In addition, comparisons to ground radar were in good agreement for both radars, with correlations to ground radar of 0.73 and 0.93. (R2 showed slightly higher accuracy than R1, with biases of –22% (R1) and –6% (R2)). Based on these results, the SMEs concluded that Tomorrow.io precipitation radar data be considered for NASA scientific use, contingent upon alignment with science objectives and application needs.
中小企业评估了该公司的二级降水产品和地理定位精度，其结果与Tomorrow.io在其算法理论基础文件中提供的分析基本一致。地理位置评估显示与数字高程模型 (DEM) 参考的“良好相关性”为 0.98。此外，两种雷达与地面雷达的比较结果非常一致，与地面雷达的相关性分别为 0.73 和 0.93。 （R2 的准确度略高于 R1，偏差为 –22% (R1) 和 –6% (R2)）。根据这些结果，SME 得出结论，Tomorrow.io 降水雷达数据可考虑用于 NASA 的科学用途，具体取决于科学目标和应用需求。
To Tomorrow.io, the CSDA program’s independent evaluation process provides the confidence the scientific community needs to rely on commercial Earth observation data.
对于 Tomorrow.io 来说，CSDA 计划的独立评估流程为科学界提供了依赖商业地球观测数据所需的信心。
“When NASA’s own subject matter experts validate that a commercially built space-based radar system can contribute meaningfully alongside programs like NASA’s Global Precipitation Measurement missions, that opens a new chapter for Earth observation,” said Rei Goffer, Chief Strategy Officer and Founder of Tomorrow.io. “We built these instruments to demonstrate that the commercial sector can deliver science-quality data from space, and we’re proud that NASA’s assessment supports that vision.”
Tomorrow.io 首席战略官兼创始人 Rei Goffer 表示：“当 NASA 自己的主题专家验证商业建造的天基雷达系统可以与 NASA 全球降水测量任务等项目一起做出有意义的贡献时，这将为地球观测翻开新的篇章。” “我们建造这些仪器是为了证明商业部门可以从太空提供科学质量的数据，我们很自豪 NASA 的评估支持这一愿景。”
NASA’s Earth Science Division (ESD) established the CSDA program to identify, evaluate, and acquire commercial remote sensing data that enhances NASA’s Earth science research and applications. CSDA provides structured on-ramping opportunities for emerging commercial satellite data vendors, enabling NASA to continuously integrate innovative data sources as the private sector evolves. By leveraging these partnerships, NASA’s ESD aims to accelerate scientific discovery and expand applications of Earth observation data for the NASA Earth science research and applications community and societal benefit.
NASA 地球科学部 (ESD) 建立了 CSDA 计划，旨在识别、评估和获取商业遥感数据，从而增强 NASA 的地球科学研究和应用。 CSDA 为新兴商业卫星数据供应商提供结构化的入门机会，使 NASA 能够随着私营部门的发展不断整合创新数据源。通过利用这些合作伙伴关系，NASA 的 ESD 旨在加速科学发现并扩大地球观测数据的应用，以造福 NASA 地球科学研究和应用社区以及社会利益。
Since its initial pilot, the CSDA Program has conducted three on-ramp activities, resulting in the addition of several vendors into sustainment. Since then, the program has streamlined its evaluation process by introducing high-quality, SME-led data assessments, accelerating reviews and strengthening NASA’s engagement with the rapidly growing commercial data ecosystem. The CSDA’s evaluation criteria include:
自最初试点以来，CSDA 计划已开展了三项入门活动，导致增加了几家供应商进行维护。从那时起，该计划通过引入高质量、中小企业主导的数据评估、加速审查以及加强 NASA 与快速增长的商业数据生态系统的接触，简化了评估流程。 CSDA的评估标准包括：
This approach ensures NASA gains timely access to high-quality, mission-relevant commercial data, and provides valuable feedback to private-sector providers, fostering innovation, improved data products, and alignment of industry capabilities with NASA’s evolving scientific needs.
这种方法可确保 NASA 及时获取与任务相关的高质量商业数据，并向私营部门提供商提供宝贵的反馈，从而促进创新、改进数据产品，并使行业能力与 NASA 不断变化的科学需求保持一致。
