挑战
美国科学和监管机构国家海洋和大气管理局 (NOAA) 的任务是提高天气建模和计算能力，作为其对 2017 年天气研究和预报创新法案承诺的一部分。该机构认识到商业来源的潜力。射电掩星 (RO) 数据可增强天气预报和对气候变化的了解。然而，在向商业航空航天公司授予合同之前，NOAA 需要评估商业 RO 数据对天气预报应用的准确性、可靠性和总体影响。为此目的启动了一项试点计划。初步评估发现，Spire Global的Level 2产品成熟稳定，对Day 1的预测产生了明显的积极影响。
关于客户
美国国家海洋和大气管理局 (NOAA) 是美国商务部下属的一个美国科学和监管机构。 NOAA 与联邦、州和地方当局协调提供环境管理服务。该机构致力于遵守 2017 年《天气研究和预报创新法案》，该法案推动天气预报和预警系统的改进，以建立一个响应迅速、有弹性的“天气就绪国家”。 NOAA 认识到气候变化是世界上最重大的挑战之一，并致力于通过数据支持的情报促进积极的变革。
解决方案
NOAA 向 Spire Global 和 GeoOptics 等商业航空航天公司授予了不定交付、不定数量 (IDIQ) 合同，为天气应用提供 RO 数据。 Spire Global 利用专有的低轨道卫星星座提供业界信赖的天基天气数据，获得了一份为期 2 年、最高金额为 2300 万美元的合同。该合同要求 Spire 开发、制造和运行卫星来收集大气数据以进行天气预报。数据必须满足特定的质量要求，包括延迟、信噪比、海拔范围、数量和地理分布。随着时间的推移，NOAA 向 Spire 和 GeoOptics 授予了四份交付订单 (DO)，每一份都具有严格的数据准确性和运营影响指南。
