Climate change is a one of societies greatest challenges, needing immediate action to prevent the most damaging of irreversible consequences. But climate change is an emotive issue, where the vicissitudes of the records and uncertainty in future predictions of the climate is used by international players to politicise the debate & excuse inaction. Climate change is a theatre where an accurate, trustable record of the state of today's climate & its reaction to anthropogenic emissions can have global impact. However, it is an exciting time in terms of monitoring of the climate & the provision of independent observational records needed to cut through the argument. Two satellite missions have recently been selected that will provide genuinely new data to inform the debate. TRUTHS has been selected as an ESA EarthWatch mission, providing an unprecedented level of accuracy in measuring the solar-reflective domain - the energy input to the climate system, expected to be launched in 2027 with a 7-10 year mission. FORUM has also recently been selected as an ESA Earth Explorer mission, measuring the mid- far-infrared portion of the outgoing longwave emission of the climate system for the first time, expected to be launched in 2026 with a nominal lifetime of 4 years. Combined with the operational EUMETSAT IASI-NG instrument, which measures the near- to mid-IR portion of the outgoing longwave emission - in the late 2020s we will, for the first time, have a space climate observatory capable of measuring the full energetic boundary conditions of the climate system at high spectral resolution. This project will study the impact of this unique combination of observations & the metrological methods needed to optimise the value obtained from their synergetic use.

气候变化是社会面临的最大挑战之一，需要立即采取行动，以防止最具破坏性的不可逆转的后果。但气候变化是一个情绪化的问题，国际参与者利用记录的变化和未来气候预测的不确定性来政治化辩论和为不作为找借口。气候变化是一个剧场，准确，可靠地记录当今气候状况及其对人为排放的反应可以产生全球影响。然而，就气候监测而言，这是一个令人兴奋的时刻&提供独立的观测记录需要切断争论。最近选定了两个卫星飞行任务，它们将提供真正的新数据，为辩论提供信息。TRUTHS已被选为欧空局地球观察使命，在测量太阳反射域（气候系统的能量输入）方面提供了前所未有的准确度，预计将于2027年发射，为期7-10年使命。论坛最近还被选为欧空局地球探测器使命，首次测量气候系统向外长波发射的中远红外部分，预计将于2026年发射，标称寿命为4年。与欧洲气象卫星应用组织的国际空间信息系统-NG仪器（用于测量长波发射的近红外至中红外部分）相结合，我们将在2020年代后期首次拥有一个能够以高光谱分辨率测量气候系统全部能量边界条件的空间气候观测站。该项目将研究这种独特的观测组合的影响，以及优化从协同使用中获得的价值所需的方法。
