Phys.org  April 4, 2022 The Moon is extremely stable and not influenced by factors on Earth like climate to any large degree. It is a very good calibration reference. An international team of researchers in (US – NIST, USGS, Canada) developed NASA’s airborne Lunar Spectral Irradiance (air-LUSI) which is a telescope that accurately measures how much light is reflected off the lunar surface to assess the amount of energy Earth-observing satellites receive from moonlight. It will help to improve the accuracy and consistency of measurements among Earth-observing satellites. The results will compliment ground-based sites. Scientists can more easily compare data […]
