  • Flash droughts characterization over China: From a perspective of the rapid intensification rate. [Journal Article]
    Sci Total Environ 2019; :135373Liu Y, Zhu Y, … Jiang S
  • Flash droughts, with rapid onset and strong intensity, have attracted much attention in recent literature due to their devastating socio-agricultural impacts. Based on the microwave remote sensing soil moisture data released by the European Space Agency Climate Change Initiative program (ESA CCI SM), flash droughts were identified by focusing on the attenuation rate of weekly soil moisture percen…
  • A Ground Support Biobarrier (GSB) for recontamination prevention. [Journal Article]
    Life Sci Space Res (Amst) 2019; 23:22-30Patel N, Dean Z, … Newlin L
  • Planetary Protection organizations at the National Aeronautics and Space Administration (NASA), the European Space Agency (ESA), and other space agencies around the world are charged with protecting icy moons and Mars Special Regions, areas that carry an increased potential for life, from Earth biological contamination. During the spacecraft assembly process subsystems undergo functional testing,…
  • Satellite-based time-series of sea-surface temperature since 1981 for climate applications. [Journal Article]
    Sci Data 2019; 6(1):223Merchant CJ, Embury O, … Donlon C
  • A climate data record of global sea surface temperature (SST) spanning 1981-2016 has been developed from 4 × 1012 satellite measurements of thermal infra-red radiance. The spatial area represented by pixel SST estimates is between 1 km2 and 45 km2. The mean density of good-quality observations is 13 km-2 yr-1. SST uncertainty is evaluated per datum, the median uncertainty for pixel SSTs being 0.1…
  • The Forest Observation System, building a global reference dataset for remote sensing of forest biomass. [Journal Article]
    Sci Data 2019; 6(1):198Schepaschenko D, Chave J, … Zo-Bi IC
  • Forest biomass is an essential indicator for monitoring the Earth's ecosystems and climate. It is a critical input to greenhouse gas accounting, estimation of carbon losses and forest degradation, assessment of renewable energy potential, and for developing climate change mitigation policies such as REDD+, among others. Wall-to-wall mapping of aboveground biomass (AGB) is now possible with satell…
  • Dynamic secondary electron emission in rough composite materials. [Journal Article]
    Sci Rep 2019; 9(1):13967Olano L, Dávila ME, … Montero I
  • The interaction of ionizing radiation with matter is of critical importance in numerous areas of science and technology like space and vacuum technology and even medicine and biotechnology. Secondary electron emission is a consequence of electron irradiation on materials. We achieve extremely low secondary electron emission yield values smaller than 0.2, even up to incident electron energies ~1 k…
  • A global view on the effect of water uptake on aerosol particle light scattering. [Journal Article]
    Sci Data 2019; 6(1):157Burgos MA, Andrews E, … Zieger P
  • A reference dataset of multi-wavelength particle light scattering and hemispheric backscattering coefficients for different relative humidities (RH) between RH = 30 and 95% and wavelengths between λ = 450 nm and 700 nm is described in this work. Tandem-humidified nephelometer measurements from 26 ground-based sites around the globe, covering multiple aerosol types, have been re-analysed and harmo…
  • GCN250, new global gridded curve numbers for hydrologic modeling and design. [Journal Article]
    Sci Data 2019; 6(1):145Jaafar HH, Ahmad FA, El Beyrouthy N
  • The USDA curve-number (CN) method is fundamental for rainfall-runoff modeling. A global CN database is not currently available for geospatial hydrologic analysis at a resolution higher than 0.1°. We developed a globally consistent, gridded dataset defining CNs at the 250 m spatial resolution from new global land cover (300 m) and soils data (250 m). The resulting data product - GCN250 - represent…
