Earth Orbit v2.1: a 3-D visualization and analysis model of Earth’s orbit, Milankovitch cycles and insolation
3-D visualization analysis model of Earth’s orbit
2014/12/18
Milankovitch theory postulates that periodic variability of Earth’s orbital elements is a major climate forcing
mechanism, causing, for example, the contemporary glaciainterglacial cycles.
Flower elliptical-orbit constellation exploiting millimetre-wave radiometry and radio occultation for meteo-climatological applications
Flower elliptical-orbit constellation millimetre-wave radiometry radio occultation meteo-climatological applications
2010/9/13
This paper reports on the potential of combining elliptical-orbit Flower constellations with millimeter-wave radiometry and radio-occultation, a mission concept briefly named FloRad2. The advantages o...
