A new news from a National Academies of Sciences, Engineering, and Medicine offers NASA a horizon for prioritizing satellite observations and measurements of Earth formed on their systematic value.
NASA’s Earth Science Division conducts a concurrent array of satellite and airborne missions for long-term tellurian observations of a land surface, biosphere, plain Earth, atmosphere, and oceans. Data from these observations are used to know Earth as an integrated complement and to support vicious governmental applications, including apparatus management, continue forecasts, meridian projections, rural production, and natural-disaster response.
Like all sovereign agencies, NASA is handling in a compelled budgetary sourroundings that necessitates creation formidable choices among competing priorities for investment. For a Earth Science Division, this plea is exacerbated by augmenting final for a information supposing by a programs and missions, as good as by congressional and executive bend instruction to commence shortcoming for nutritious a series of measurements that were before upheld by other sovereign agencies.
NASA’s stream routine for creation decisions about Earth-observation priorities is essentially qualitative. As an alternative, a horizon presented in a new news provides a partially quantitative and pure proceed that rates a relations significance of opposite measurements formed on their systematic value. (The news does not tell NASA that observations to prioritize, though instead offers methodologies and metrics that NASA can use to settle priorities.)
The news recommends that NASA start by building a tiny set of quantified objectives for a earth scholarship measurements, regulating a same sources it uses to arise a module devise – a accord priorities of a systematic village voiced in a Academies’ decadal surveys, as good as superintendence from a executive and congressional branches. The news offers examples to illustrate a form of a quantified objective, such as last a rate of tellurian meant sea-level arise or a change in sea feverishness storage within a quantified operation of uncertainty. NASA should afterwards rate a advantage of a sold dimensions to assembly a quantified design formed on a tiny set of characteristics — importance, utility, quality, and success probability. Considering these ratings, as good as affordability, will capacitate NASA to heed a relations value of competing measurements.
The news illustrates use of a horizon with scholarship objectives, though records that it could also be practical to assistance NASA prioritize measures in terms of their attribute to governmental benefits. However, this use of a horizon would need NASA to establish how to brand and consider quantified objectives in this area.
