The geomorphology of Ceres [PDF]

Science, 2016
INTRODUCTION Observations of Ceres, the largest object in the asteroid belt, have suggested that the dwarf planet is a geologically differentiated body with a silicate core and an ice-rich mantle. Data acquired by the Dawn spacecraft were used to perform a three-dimensional characterization of the surface to determine if the ...

Cryovolcanism on Ceres [PDF]

Science, 2016
INTRODUCTION Classic volcanism prevalent on terrestrial planets and volatile-poor protoplanets, such as asteroid Vesta, is based on silicate chemistry and is often expressed by volcanic edifices (unless erased by impact bombardment).

The effects of different footprint sizes and cloud algorithms on the top-of-atmosphere radiative flux calculation from the Clouds and Earth's Radiant Energy System (CERES) instrument on Suomi National Polar-orbiting Partnership (NPP) [PDF]

Atmospheric Measurement Techniques, 2017
Only one Clouds and Earth's Radiant Energy System (CERES) instrument is onboard the Suomi National Polar-orbiting Partnership (NPP) and it has been placed in cross-track mode since launch; it is thus not possible to construct a set of angular ...

Evaporation process study through in situ and remote sensing data at Tres Quebradas Salt flat

Revista de Teledetección, 2019
The calculation of evaporation (Ev) is a fundamental process on the planning of investment for nonmetallic mining in salt flats. Dispose to reliable estimates of evaporation allows to reduce one of the main uncertainties of the flow models in this type ...

Appropriate sampling methods and statistics can tell apart fraud from pesticide drift in organic farming

Scientific Reports, 2021
Pesticide residues are much lower in organic than in conventional food. The article summarizes the available residue data from the EU and the U.S. organic market. Differences between samples from several sources suggest that organic products are declared

Ceres’ sunlight atlas [PDF]

Astronomy & Astrophysics, 2010
Context. Astronomical research dealing with accurate radial velocity measurements need reliable astronomical standards to calibrate the spectrographs and to assess possible systematics. Stellar radial velocity standards offer a reference at the level of a few hundred m s −1 and are not adequate for most present needs. Aims. We aim to show that sunlight
