Abstract

Numerous efforts to measure land surface fluxes, from leaf to canopy scales, have significantly advanced the field of biogeoscience. However, upscaling these estimates to larger spatial and temporal scales remains a challenge. Recent advancements in remote sensing provide new opportunities to bridge these gaps in upscaling efforts. In this review, I propose that emerging satellite data can support the robust upscaling of land surface fluxes in terms of space through constellations of low Earth orbit satellites, in time through geostationary satellites, and in spectrum via optical, thermal, and microwave satellites. Lastly, I recommend the development of a long-term network integrating tower-based hyperspectral, thermal, and microwave instruments to rigorously evaluate the upscaling process of land surface fluxes.

通过超分辨率遥感技术提升陆地表面通量的空间、时间和频谱尺度
测量从叶片到树冠尺度的陆地表面通量的大量工作极大地推动了生物地球科学领域的发展。然而,将这些估算结果放大到更大的时空尺度仍然是一项挑战。遥感技术的最新进展为弥补这些差距提供了新的机会。在这篇综述中,我提出新出现的卫星数据可以通过低地球轨道卫星群支持陆地表面通量在空间上的有力提升,通过地球静止卫星支持时间上的提升,以及通过光学、热学和微波卫星支持频谱上的提升。最后,我建议开发一个长期网络,整合塔式高光谱、热和微波仪器,以严格评估陆地表面通量的放大过程。

期刊介绍: JGR-Biogeosciences focuses on biogeosciences of the Earth system in the past, present, and future and the extension of this research to planetary studies. The emerging field of biogeosciences spans the intellectual interface between biology and the geosciences and attempts to understand the functions of the Earth system across multiple spatial and temporal scales. Studies in biogeosciences may use multiple lines of evidence drawn from diverse fields to gain a holistic understanding of terrestrial, freshwater, and marine ecosystems and extreme environments. Specific topics within the scope of the section include process-based theoretical, experimental, and field studies of biogeochemistry, biogeophysics, atmosphere-, land-, and ocean-ecosystem interactions, biomineralization, life in extreme environments, astrobiology, microbial processes, geomicrobiology, and evolutionary geobiology
