China’s Wealth Capital Stock Mapping via Machine Learning Methods

Remote Sensing, 2023
The frequent occurrence of extreme weather and the development of urbanization have led to the continuously worsening climate-related disaster losses. Socioeconomic exposure is crucial in disaster risk assessment. Social assets at risk mainly include the

Instant transport maps on 2D grids [PDF]

ACM Transactions on Graphics, 2018
In this paper, we introduce a novel and extremely fast algorithm to compute continuous transport maps between 2D probability densities discretized on uniform grids. The core of our method is a novel iterative solver computing the L 2 optimal transport map from a grid to the uniform density in the 2D ...

High-resolution inversion of methane emissions in the Southeast US using SEAC⁴RS aircraft observations of atmospheric methane: anthropogenic and wetland sources [PDF]

Atmospheric Chemistry and Physics, 2018
We use observations of boundary layer methane from the SEAC4RS aircraft campaign over the Southeast US in August–September 2013 to estimate methane emissions in that region through an inverse analysis with up to 0.25° × 0.3125° (25×25 km2) resolution

Optimal interpolation of global dissolved oxygen: 1965–2015

Geoscience Data Journal, 2022
Oxygen inventory of the global ocean has declined in recent decades potentially due to the warming‐induced reduction in solubility as well as the circulation and biogeochemical changes associated with ocean warming and increasing stratification.
