Alpha-particle emissivity of the moon: an observed upper limit

WebAstronomy & Astrophysics (A&A) Web(a) The surface roughness of the Moon decreases with scale. We quantify the surface roughness by calculating the bidirectional RMS slope angle measured using altimetry data obtained by the Lunar Orbiter Laser Altimeter (LOLA). RMS slope on scales<1 cm is based on estimates by Bandfield et al. (2015) and Helfenstein and Shepard (1999). WebMeasurements made by the moon-orbiting spacecraft Explorer 35 during 1967-1968 show that it is unlikely that the alpha-particle emissivity of the moon is greater than 0.064 per square centimeter per second per steradian and exceedingly unlikely that it is greater than 0.128, these values being respectively 0.1 and 0.2 of the provisional estimates made by … ron swanson office picture

Emissivity is an important factor in all calculations involving Stefan-Boltzmann’s Law: q = εσT⁴. where q is the flux in W/m². Most of the time in climate science the emissivity (ε) is presumed to be 1. Scientist Roy Spencer likes to use ε=0.98 ( link ): Webalpha-particle emissivity of the moon.

WebMEASUREMENT of the temperature of the Moon is generally done by absolute radiometry assuming the emissivity of the lunar surface to be independent of wave-length and to be that of a ‘black-body ... The emissivity of the surface of a material is its effectiveness in emitting energy as thermal radiation. Thermal radiation is electromagnetic radiation that most commonly includes both visible radiation (light) and infrared radiation, which is not visible to human eyes. A portion of the thermal radiation from very hot objects (see photograph) is easily visible to the eye. The emissivity of a surface depends on its chemical composition and geometrical structure. Qu…
