修正案 72：新机遇：A.17 水圈

Amendment 72: New Opportunity: A.17 Hydrosphere

A.17 水圈（Hydrosphere）旨在征集关于地球水圈的研究，以推进对地球海洋、陆地和大气中水物理过程的理解。该水圈要素由三个地球科学学科组成：海洋物理学、陆地水文学和降水科学。其共同目标是解决关于水在地球系统中分布、运动和转化的基本问题。

A.17 Hydrosphere solicits research on the Earth's Hydrosphere: to advance the understanding of the physics of Earth’s water across the ocean, land, and the atmosphere. This Hydrosphere element is composed of three Earth science disciplines: ocean physics, terrestrial hydrology, and precipitation science. The overlapping goals of are to address fundamental questions about the distribution, movement, and transformation of water across the Earth system.

具体而言，该 ROSES 要素针对海洋盐度、积雪深度以及商用卫星（commercial satellite）降水测量的相关指标。这些研究均增强了美国国家航天局（NASA）在“河流输出与地表水文学归宿”（Fate of River Export and Surface Hydrology）实地考察项目、NISAR 任务以及通过 NASA 商用卫星数据采集（data acquisition）计划所获数据方面的投入。第四个子要素鼓励将这些主题的范围扩大到上述核心学科之内及之外的其他地球科学领域。

Specifically, this ROSES element targets measurements of ocean salinity, snow depth, and commercial satellite measurements of precipitation. These all enhance NASA investments in the Fate of River Export and Surface Hydrology field campaign, the NISAR mission, and data acquired via the NASA Commercial Satellite Data Acquisition program. A fourth subelement encourages the broadening of scope of these topics to other earth science disciplines across and outside of these core disciplines.

ROSES-2025 修正案 72 将 A.17 水圈作为 ROSES-25 中的一项新机遇发布。第一阶段提案截止日期为 2026 年 10 月 8 日，第二阶段提案截止日期为 2027 年 1 月 28 日。

ROSES-2025 Amendment 72 releases A.17 Hydrosphere as a new opportunity in ROSES-25. Step-1 proposals are due October 8, 2026, and Step-2 proposals are due January 28, 2027.

针对该项目要素潜在提案人的说明会将于东部时间（Eastern Time）9 月 14 日星期一，下午 2 点至 3 点举行。连接信息将发布在该项目要素的 NSPIRES 页面“其他文档”栏目下。

A briefing for potential proposers to this program element will occur Monday, September 14, from 2-3 PM Eastern Time. Connection information will be posted under "other documents" on the NSPIRES page for this program element.
