| 1 | Global spatio-temporally harmonised datasets for producing high-resolution gridded population distribution datasets显示文摘Multi-temporal,globally consistent,high-resolution human population datasets provide consistent and comparable population distributions in support of mapping sub-national heterogeneities in health,wealth,and resource access,and monitoring change in these over time.The production of more reliable and spatially detailed population datasets is increasingly necessary due to the importance of improving metrics at sub-national and multitemporal scales.This is in support of measurement and monitoring of UN Sustainable Development Goals and related agendas.In response to these agendas,a method has been developed to assemble and harmonise a unique,open access,archive of geospatial datasets.Datasets are provided as global,annual time series,where pertinent at the timescale of population analyses and where data is available,for use in the construction of population distribution layers.The archive includes sub-national census-based population estimates,matched to a geospatial layer denoting administrative unit boundaries,and a number of co-registered gridded geospatial factors that correlate strongly with population presence and density.Here,we describe these harmonised datasets and their limitations,along with the production workflow.Further,we demonstrate applications of the archive by producing multi-temporal gridded population outputs for Africa and using these to derive health and development metrics.The geospatial archive is available at http://gffzzd3cc09b8251d45dfsfoucw0696wvw6nbq.ffgz.tsg.suse.edu.cn/10.5258/SOTON/WP00650. | Christopher T.Lloyd Heather Chamberlain David Kerr Greg Yetman Linda Pistolesi Forrest R.Stevens Andrea E.Gaughan Jeremiah J.Nieves Graeme Hornby Kytt MacManus Parmanand Sinha Maksym Bondarenko Alessandro Sorichetta Andrew J.Tatem | 2019 | Big Earth Data2019，3，2： | 4 |

| 4 | Comparisons of two global built area land cover datasets in methods to disaggregate human population in eleven countries from the global South显示文摘Mapping built land cover at unprecedented detail has been facilitated by increasing availability of global high-resolution imagery and image processing methods.These advances in urban feature extraction and built-area detection can refine the mapping of human population densities,especially in lower income countries where rapid urbanization and changing population is accompanied by frequently out-of-date or inaccurate census data.However,in these contexts it is unclear how best to use built-area data to disaggregate areal,count-based census data.Here we tested two methods using remotely sensed,built-area land cover data to disaggregate population data.These included simple,areal weighting and more complex statistical models with other ancillary information.Outcomes were assessed across eleven countries,representing different world regions varying in population densities,types of built infrastructure,and environmental characteristics.We found that for seven of 11 countries a Random Forest-based,machine learning approach outperforms simple,binary dasymetric disaggregation into remotely-sensed built areas.For these more complex models there was little evidence to support using any single built land cover input over the rest,and in most cases using more than one built-area data product resulted in higher predictive capacity.We discuss these results and implications for future population modeling approaches. | Forrest R.Stevens Andrea E.Gaughan Jeremiah JNieves Adam King Alessandro Sorichetta Catherine Linard Andrew JTatem | 2020 | International Journal of Digital Earth2020，13，1： | 1 |

| 6 | Fast indirect measurement of PCDD/F TEQ emission from municipal solid waste incineration:a review显示文摘Landfilling,a traditional and major method for municipal solid waste management,is gradually being taken place by incin-eration.However,the contamination problem caused by polychlorinated dibenzo-p-dioxin and dibenzofuran(PCDD/F)emissions from incineration has also brought much concerns.Traditional offline method based on high-resolution gas chromatography coupled with high-resolution mass spectrometry for the determination of PCDD/F emissions is expensive,infrequent and time-lagging.Use of PCDD/F indicators to achieve fast indirect measurements for PCDD/Fs is a much more promising method.Six categories of potential PCDD/F indicators are discussed in this paper:CO,total hydrocarbons,specific PCDD/F congeners,polycyclic aromatic hydrocarbons,chlorophenols and chlorobenzenes.Their performance as PCDD/F indicators are verified in the following criteria:(1)structural similarities;(2)known mechanistic arguments;(3)known cor-relation values from the literature and(4)detectability.Comprehensively considering the four factors,chlorobenzenes may be the best suitable PCDD/F indicator.One analytical method based on Photon Ionization coupled with Time-of-Flight Mass Spectrometry has been proved effective for the online/atline measurements for PCDD/F indicators for the prediction of TEQ in incineration process.Moreover,thermal desorption and gas chromatography can be applied to provide extra separation and concentration for very complex matrices with extremely low concentrations. | Xuan Cao Shengyong Lu William R.Stevens Huadong Zhong Kaicheng Wu Xiaodong Li Jianhua Yan | 2019 | Waste Disposal and Sustainable Energy2019，1，1： | 0 |
| 7 | Modelling changing population distributions:an example of the Kenyan Coast,1979–2009显示文摘Large-scale gridded population datasets are usually produced for the year of input census data using a top-down approach and projected backward and forward in time using national growth rates.Such temporal projections do not include any subnational variation in population distribution trends and ignore changes in geographical covariates such as urban land cover changes.Improved predictions of population distribution changes over time require the use of a limited number of covariates that are time-invariant or temporally explicit.Here we make use of recently released multi-temporal high-resolution global settlement layers,historical census data and latest developments in population distribution modelling methods to reconstruct population distribution changes over 30 years across the Kenyan Coast.We explore the methodological challenges associated with the production of gridded population distribution time-series in data-scarce countries and show that trade-offs have to be found between spatial and temporal resolutions when selecting the best modelling approach.Strategies used to fill data gaps may vary according to the local context and the objective of the study.This work will hopefully serve as a benchmark for future developments of population distribution time-series that are increasingly required for population-at-risk estimations and spatial modelling in various fields. | Catherine Linard Caroline W.Kabaria Marius Gilbert Andrew J.Tatem Andrea E.Gaughan Forrest R.Stevens Alessandro Sorichetta Abdisalan M.Noor Robert W.Snow | 2017 | International Journal of Digital Earth2017，10，10： | 0 |
