Regular photometric observations of the moon's “ashen light” (earthshine) from the Big Bear Solar Observatory (BBSO) since December 1998 have quantified the earth's optical reflectance. We find large (∼5%) daily variations in the reflectance due to large‐scale weather changes on the other side of the globe. Separately, we find comparable hourly variations during the course of many nights as the earth's rotation changes that portion of the earth in view. Our data imply an average terrestrial… 

Earthshine and the Earth's albedo: 2. Observations and simulations over 3 years

[1] Since late 1998, we have been making sustained measurements of the Earth's reflectance by observing the earthshine from Big Bear Solar Observatory. Further, we have simulated the Earth's

Earth's Albedo 1998–2017 as Measured From Earthshine

The reflectance of the Earth is a fundamental climate parameter that we measured from Big Bear Solar Observatory between 1998 and 2017 by observing the earthshine using modern photometric techniques

SUNSHINE, EARTHSHINE AND CLIMATE CHANGE: II. SOLAR ORIGINS OF VARIATIONS IN THE EARTH`S ALBEDO

There are terrestrial signatures of the solar activity cycle in ice core data (Ram & Stoltz 1999), but the variations in the sun`s irradiance over the cycle seem too small to account for the

Interannual variations in Earth's reflectance 1999–2007

[1] The overall reflectance of sunlight from Earth is a fundamental parameter for climate studies. Recently, measurements of earthshine were used to find large decadal variability in Earth's

Globally Integrated Measurements of the Earth’s Visible Spectral Albedo

We report spectroscopic observations of the earthshine reflected from the Moon. By applying our well-developed photometry methodology to spectroscopy, we are able to precisely determine the Earth's

Earthshine and the Earth's albedo: 1. Earthshine observations and measurements of the lunar phase function for accurate measurements of the Earth's Bond albedo

[1] We have been making sustained observations of the earthshine from Big Bear Solar Observatory in California since late 1998. We also have intermittent observations from 1994–1995. We have

Earth’s albedo time series reveals low radiative energy input in December 2020

The Earth’s spherical albedo describes the ratio of light reflected from the Earth to that incident from the Sun, an important input variable for the Earth’s radiation balance. The spherical albedo

Temporal Variation of the Shortwave Spherical Albedo of the Earth

The Earth’s spherical albedo describes the ratio of light reflected from the Earth to that incident from the Sun, an important variable for the Earth’s radiation balance. The spherical albedo has

Measurements of the Surface Brightness of the Earthshine with Applications to Calibrate Lunar Flashes

We have used the large database of photometric observations of the bright and dark portions of the face of the Moon from the Earthshine Project at Big Bear Solar Observatory to determine the surface

Global Change and the Dark of the Moon

Earthshine--the faint, reflected glow that sometimes illuminates the dark disk of the new moon--may hold valuable clues as to whether the earth is gradually getting warmer.
