The Collection 6 MODIS aerosol products over land and ocean [PDF]

open access: yesAtmospheric Measurement Techniques, 2013
The twin Moderate resolution Imaging Spectroradiometer (MODIS) sensors have been flying on Terra since 2000 and Aqua since 2002, creating an extensive data set of global Earth observations.

Global top-down smoke-aerosol emissions estimation using satellite fire radiative power measurements [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
Fire emissions estimates have long been based on bottom-up approaches that are not only complex, but also fraught with compounding uncertainties. We present the development of a global gridded (1° × 1°) emission coefficients (Ce) product for smoke total ...

Postsynaptic density radiation signature following space irradiation

open access: yesFrontiers in Physiology, 2023
Introduction: The response of the brain to space radiation is an important concern for astronauts during space missions. Therefore, we assessed the response of the brain to 28Si ion irradiation (600 MeV/n), a heavy ion present in the space environment ...

Karymsky volcano eruptive plume properties based on MISR multi-angle imagery and the volcanological implications [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
Space-based operational instruments are in unique positions to monitor volcanic activity globally, especially in remote locations or where suborbital observing conditions are hazardous.

Evaluation of deep space exploration risks and mitigations against radiation and microgravity

open access: yesFrontiers in Nuclear Medicine, 2023
Ionizing radiation and microgravity are two considerable health risks encountered during deep space exploration. Both have deleterious effects on the human body.

Deep Space Observations of Terrestrial Glitter

open access: yesEarth and Space Science, 2021
Deep space climate observatory (DSCOVR) spacecraft drifts about the Lagrangian point ≈1.4–1.6 × 106 km from Earth, where its Earth polychromatic imaging camera (EPIC) observes the sun‐lit face of the Earth every 1 to 2 hours.

Overexpression of catalase in mitochondria mitigates changes in hippocampal cytokine expression following simulated microgravity and isolation

open access: yesnpj Microgravity, 2021
Isolation on Earth can alter physiology and signaling of organs systems, including the central nervous system. Although not in complete solitude, astronauts operate in an isolated environment during spaceflight.

Immediate effects of acute Mars mission equivalent doses of SEP and GCR radiation on the murine gastrointestinal system-protective effects of curcumin-loaded nanolipoprotein particles (cNLPs)

open access: yesFrontiers in Astronomy and Space Sciences, 2023
Introduction: Missions beyond low Earth orbit (LEO) will expose astronauts to ionizing radiation (IR) in the form of solar energetic particles (SEP) and galactic cosmic rays (GCR) including high atomic number and energy (HZE) nuclei. The gastrointestinal

Study of Modeling Parameters in Determination of TID, DD, and SEE Radiation Damages for Satellite in LEO Orbit Using OMERE Software [PDF]

open access: yesفصلنامه علوم و فناوری فضایی, 2019
One of the important issues to be considered in the design of space systems is the attention to the difference between the terrestrial and space environment. This issue changes the design and affects all subsystems of space systems.
