Development of new open and free multi-temporal global population grids at 250 m resolution

  
In Proceedings of the 19th AGILE International Conference on Geographic Information Science (2016)

Abstract

Global population grids are increasingly required and used for countless applications in analysis, modeling, and policy-making. However, better and comparable global information requires improved geospatial data on population distribution and densities, in particular concerning temporal and spatial resolution and capacity for change assessment. [\n] This paper presents the development of improved global multi-temporal population grids, ...

 

First- and second-order conservative remapping schemes for grids in spherical coordinates

  
Monthly Weather Review In Monthly Weather Review, Vol. 127, No. 9. (1 September 1999), pp. 2204-2210, https://doi.org/10.1175/1520-0493(1999)127<2204:fasocr>2.0.co;2

Abstract

Coupling atmosphere, ocean, sea ice, and land surface models requires a means for remapping fields between grids in an accurate and conservative manner. A method is described here for computing interpolation weights for first- and second-order conservative remappings. The method is completely general and can be used for any grid on a sphere. ...

High resolution global gridded data for use in population studies

  
Scientific Data, Vol. 4 (31 January 2017), 170001, https://doi.org/10.1038/sdata.2017.1

Abstract

Recent years have seen substantial growth in openly available satellite and other geospatial data layers, which represent a range of metrics relevant to global human population mapping at fine spatial scales. The specifications of such data differ widely and therefore the harmonisation of data layers is a prerequisite to constructing detailed and contemporary spatial datasets which accurately describe population distributions. Such datasets are vital to measure impacts of population growth, monitor change, and plan interventions. To this end the WorldPop Project ...

A gridded global data set of soil, intact regolith, and sedimentary deposit thicknesses for regional and global land surface modeling

  
Journal of Advances in Modeling Earth Systems, Vol. 8, No. 1. (March 2016), pp. 41-65, https://doi.org/10.1002/2015ms000526

Abstract

Earth's terrestrial near-subsurface environment can be divided into relatively porous layers of soil, intact regolith, and sedimentary deposits above unweathered bedrock. Variations in the thicknesses of these layers control the hydrologic and biogeochemical responses of landscapes. Currently, Earth System Models approximate the thickness of these relatively permeable layers above bedrock as uniform globally, despite the fact that their thicknesses vary systematically with topography, climate, and geology. To meet the need for more realistic input data for models, we developed a high-resolution ...

 

2D Euclidean distance transform algorithms: a comparative survey

  
ACM Computing Surveys, Vol. 40, No. 1. (February 2008), pp. 1-44, https://doi.org/10.1145/1322432.1322434

Abstract

The distance transform (DT) is a general operator forming the basis of many methods in computer vision and geometry, with great potential for practical applications. However, all the optimal algorithms for the computation of the exact Euclidean DT (EDT) were proposed only since the 1990s. In this work, state-of-the-art sequential 2D EDT algorithms are reviewed and compared, in an effort to reach more solid conclusions regarding their differences in speed and their exactness. Six of the best algorithms were fully implemented ...

 

A general algorithm for computing distance transforms in linear time

  
Mathematical Morphology and its Applications to Image and Signal Processing In Mathematical Morphology and its Applications to Image and Signal Processing, Vol. 18 (2000), pp. 331-340, https://doi.org/10.1007/0-306-47025-x_36

Abstract

A new general algorithm for computing distance transforms of digital images is presented. The algorithm consists of two phases. Both phases consist of two scans, a forward and a backward scan. The first phase scans the image column-wise, while the second phase scans the image row-wise. Since the computation per row (column) is independent of the computation of other rows (columns), the algorithm can be easily parallelized on shared memory computers. The algorithm can be used for the computation of the ...

 

Climatologies at high resolution for the earth's land surface areas

  
Scientific Data, Vol. 4 (Sep 2017), 170122, https://doi.org/10.1038/sdata.2017.122

Abstract

High-resolution information on climatic conditions is essential to many applications in environmental and ecological sciences. Here we present the CHELSA (Climatologies at high resolution for the earth’s land surface areas) data of downscaled model output temperature and precipitation estimates of the ERA-Interim climatic reanalysis to a high resolution of 30 arc sec. The temperature algorithm is based on statistical downscaling of atmospheric temperatures. The precipitation algorithm incorporates orographic predictors including wind fields, valley exposition, and boundary layer height, with a subsequent bias correction. ...

 

CHELSA climatologies at high resolution for the earth's land surface areas (Version 1.1)

  

Abstract

CHELSA_v1.1 (http://chelsa-climate.org/) is a high resolution (30 arc sec, ~1 km) climate data set for the earth land surface areas. It includes monthly and annual mean temperature and precipitation patterns as well as derived bioclimatic and interannual parameters for the time period 1979-2013. CHELSA_v1.1 is based on a quasi-mechanistical statistical downscaling of the ERA interim global circulation model (http://www.ecmwf.int/en/research/climate-reanalysis/era-interim) with a GPCC (https://www.dwd.de/EN/ourservices/gpcc/gpcc.html) and GHCN (https://www.ncdc.noaa.gov/ghcnm/) bias correction. ...

 

MSWEP: 3-hourly 0.25° global gridded precipitation (1979–2015) by merging gauge, satellite, and reanalysis data

  
Hydrology and Earth System Sciences Discussions (30 May 2016), pp. 1-38, https://doi.org/10.5194/hess-2016-236

Abstract

Current global precipitation (P) datasets do not take full advantage of the complementary nature of satellite and reanalysis data. Here, we present Multi-Source Weighted-Ensemble Precipitation (MSWEP), a global P dataset for the period 1979–2015 with a 3-hourly temporal and 0.25° spatial resolution, specifically designed for hydrological modeling. The design philosophy of MSWEP was to optimally merge the highest quality P data sources available as a function of time scale and location. The long-term mean of MSWEP was based on the CHPclim ...

 

Spatial downscaling of European climate data

  
Int. J. Climatol., Vol. 36, No. 3. (1 March 2016), pp. 1444-1458, https://doi.org/10.1002/joc.4436

Abstract

E-OBS(European Observations) is a gridded climate data set which contains maximum temperature, minimum temperature, and precipitation on a daily time step. The data can be as fine as 0.25° in resolution and extends over the entire European continent and parts of Africa and Asia. However, for studying regional or local climatic effects, a finer resolution would be more appropriate. A continental data set with resolution would allow research that is large in scale and still locally relevant. Until now, a climate ...

 

Impacts of uncertainties in European gridded precipitation observations on regional climate analysis

  
Int. J. Climatol., Vol. 37, No. 1. (1 March 2017), pp. 305-327, https://doi.org/10.1002/joc.4706

Abstract

Gridded precipitation data sets are frequently used to evaluate climate models or to remove model output biases. Although precipitation data are error prone due to the high spatio-temporal variability of precipitation and due to considerable measurement errors, relatively few attempts have been made to account for observational uncertainty in model evaluation or in bias correction studies. In this study, we compare three types of European daily data sets featuring two Pan-European data sets and a set that combines eight very high-resolution ...
