This focus area provides the community involved in the production and validation of satellite- based woody aboveground biomass products with a forum for documenting accepted good practices in an open and transparent manner, that is scientifically defensible. This ‘title’ document (V1.0) has undergone review by remote sensing experts from across the globe. This represents the current state of knowledge for satellite biomass remote sensing and includes a summary of current knowledge and data gaps toward operational validation of products at a global scale. We note that currently (March, 2021), no globally representative, systematically collected reference system for biomass product validation is available. We make recommendations for new data collections specifically designed for this purpose, but acknowledge that these recommendations and the authorship for this document are biased toward tropical moist forests. While we attempt to make recommendations that are applicable to all ecosystems, we note that forest ecosystems are dynamic and structurally complex, and a single set of recommendations will not apply to all ecosystems. Additionally, existing reference datasets, such as National Forest Inventories (NFIs), provide critical data addressing many needs beyond the validation of biomass products. While our recommendations focus on ideal datasets for validation and inter-comparison at the plot and pixel scale, we stress that our recommendations may be impractical in some cases, and should not replace, but complement, existing datasets that are maintained by in-country organizations, such as NFIs. This document is published in advance of forthcoming biomass products from a new generation of lidar and SAR sensors (e.g. NASA’s GEDI, NASA-ISRO’s NISAR, ESA’s BIOMASS), and will undoubtedly be updated as we learn from the development and validation of these products. This protocol focuses on aboveground woody biomass stock, and thus future extensions are anticipated that may provide guidance on other biomass pools (e.g. non-woody), and on biomass change. It is therefore expected that this protocol document and recommendations will undergo subsequent regular iterations based on community feedback and scientific advancement. Finally, we gratefully acknowledge several expert reviewers whose thoughtful comments substantially improved this document. We welcome experts to participate in the ongoing improvement of this document and invite the broader community to make use of it for their research and applications related to woody biomass products derived from satellite data. All contributors will be recognized as such in the document and on the CEOS WGCV LPV website. Sincerely, The Editors, Laura Duncanson, University of Maryland,

  • 5.4 SAR Remote Sensing of Forest Biomass
    CHAPTER 5 SAR Methods for Mapping and Monitoring Forest Biomass Sassan Saatchi, Senior Research Scientist, Carbon Cycle and Ecosystems Section, Jet Propulsion Laboratory, California Institute of Technology ABSTRACT Forests play a major role in the global carbon cycle, sequestrating more than 25% of the carbon emitted to the atmosphere from fossil fuel consumption and land- use changes. The accumulation of carbon in forests has therefore become an efective strategy for mitigating climate change and an important mechanism for countries to meet their emission requirements under many international protocols and agreements. Remote sensing techniques are considered the most promis- ing approach for providing up-to-date information on the status of forest cover and carbon stocks at diferent scales. Among remote sensing techniques, Synthetic Aperture Radar (SAR) sensors at long wavelengths have the advantage of strong sensitivity to the forest Above Ground Biomass (AGB) and the ability to quantify and monitor carbon stocks at the scale in which human activities occur. This chapter provides a summary of the methodologies and techniques for estimating forest AGB and monitoring changes from existing and future SAR satellite systems. The material in this chapter is designed to help both practitioners and remote sensing students and experts use SAR imagery for mapping and monitoring forest biomass. The examples and the bibliography capture the state of the art in SAR remote sensing of vegetation structure and biomass, and provide resources for enthusiasts to follow future developments in the technology and the methodology. 5.1 Background put together the information from diferent types of carbon, water, and nutrients).

  • The Temple of Quetzalcoatl and the Cult of Sacred War at Teotihuacan
    CHAPTER 7 TheTempleofQuetzalcoatlandthe Cultof Sacred Warat Teotihuacan The Temple of Quetzalcoatl at Teotihuacan has been the source of startling archaeological discoveries since the early portion of this century. Beginning in 1918, excavations by Manuel Gamio revealed an elaborate and beautifully preserved facade underlying later construc- tion. Although excavations were performed intermittently during the subsequent decades, some of the most important discoveries have occurred during the last several years. Recent investigations have revealed mass dedicatory burials in the foundations of the Temple of Quetzalcoatl (Sugiyama 1989a; Cabrera Castro et al. 1988); at the time of this writing, more than eighty individuals have been discovered interred in the foundations of the pyramid. Sugiyama (1989a) persuasively argues that many of the individuals appear to be either war- riors or dressed in the office of war. The archaeological investigations by Cabrera, Sugiyama, and Cowgill are ongoing, and to comment extensively on the implications of their work would be both premature and presumptuous. Nonetheless, the recent excavations have placed an entirely new light on the significance of the Temple of Quetzalcoatl and its remarkable sculptural format. In this study, I will be concerned with the iconographic meaning of the Temple of Quetzalcoatl facade. In recent work, I noted that the temple facade represents serpents passing through a facade of circular mirrors (Taube 1986, 1988e). Two forms of serpents are present, Quetzalcoatl and an ancestral form of the Xiuhcoatl. In this respect, the Temple of Quetzalcoatl facade may be compared to the Postclassic wind temple of Ehecatl-Quetzalcoatl, which also appears To cite this chapter: with mirrors and serpents (Taube 1986).
