Precipitation Observing System Architecture Options Rough Order of Magnitude Cost Model

This XL file was generated to estimate the annual Rough Order of Magnitude (ROM, -25% / +75%) costs for different implementation options for a precipitation climate variable observing system. The objective of this cost estimate exercise was to get an approximate feel for the average annual operating costs of potentially very different implementation approaches to achieving a 1 day repeat Ka band global precipitation measurement from space. The information in this file was pulled together in support of the Keck Institute for Space Studies (KISS) the study “Developing a Continuity Framework for Satellite Observations of Climate”, and is supplemental data to the study report titled "Towards a U.S. Framework for Continuity of Satellite Observations of Earth’s Climate and for Supporting Societal Resilience", submitted to American Geophysical Union’s journal Earth’s Future.

本XL文件旨在估算降水气候变量观测系统不同实施方案的年度粗略量级（Rough Order of Magnitude, ROM，误差范围为-25% / +75%）成本。本次成本估算工作的目标，是大致掌握通过截然不同的实施途径，实现基于天基平台的单日重访Ka波段全球降水测量所需的年均运行成本范围。本文件所汇总的信息，是为支持凯克空间研究学院（Keck Institute for Space Studies, KISS）开展的题为《气候卫星观测连续性框架构建(Developing a Continuity Framework for Satellite Observations of Climate)》的研究而整理，同时作为提交至美国地球物理联合会（American Geophysical Union）旗下期刊《地球未来(Earth’s Future)》的题为《构建美国地球气候卫星观测连续性框架并支撑社会韧性(Towards a U.S. Framework for Continuity of Satellite Observations of Earth’s Climate and for Supporting Societal Resilience)》的研究报告的补充数据。详情请见：https://www.kiss.caltech.edu/workshops/ClimateFramework/ClimateFramework.html。
