Noise Sources in Photometry and Radial Velocities

, 2017
The quest for Earth-like, extrasolar planets (exoplanets), especially those located inside the habitable zone of their host stars, requires techniques sensitive enough to detect the faint signals produced by those planets.

Keyword Recommendation Methods for Earth Science Data Considering Hierarchical Structure of Vocabularies [PDF]

Proceedings of the ACM/IEEE Joint Conference on Digital Libraries in 2020, 2020
To understand and properly use scientific data, it is important that the metadata, which describes information related to data, contains sufficient information. Keywords are one of the metadata items, and for assigning keywords to the earth science dataset, it is common to select and assign appropriate keywords from a controlled vocabulary with a ...

Assessing river discharge dynamics through relative surface water extent changes in river basins

iScience
Summary: Surface water in rivers is vital for human society. However, our current understanding of the dynamics and drivers of river flows relies predominantly on stream gauging data, which are limited in spatial coverage and involve significant costs ...
