“…Compared to broadband sensors, data from multispectral radiometers are more profuse and offer higher spatial resolution. Some researchers have attempted to take advantage of such multispectral satellite imagery to retrieve planetary albedo (Lee et al 2018;Niu and Pinker 2012;Song et al 2018;Wang andLiang 2016, 2017). Niu and Pinker (2012) developed a two-step approach to first convert narrowband radiance measured by Spinning Enhanced Visible Infrared Imager (SEVIRI) to broadband radiance and then apply ADMs to retrieve TOA albedo.…”

The Earth's climate is largely determined by its energy budget. Since the 1960s, satellite remote sensing has been used in estimating these energy budget components at both the top of the atmosphere (TOA) and the surface. Besides the broadband sensors that have been traditionally used for monitoring Earth's Energy Budget (EEB), data from a variety of narrowband sensors aboard both polar-orbiting and geostationary satellites have also been extensively employed to estimate the EEB components. This paper provides a comprehensive review of the satellite missions, state-of-the art estimation algorithms and the satellite products, and also synthesizes current understanding of the EEB and spatiotemporal variations. The TOA components include total solar irradiance, reflected shortwave radiation/planetary albedo, outgoing longwave radiation, and energy imbalance. The surface components include incident solar radiation, shortwave albedo, shortwave net radiation, longwave downward and upwelling radiation, land and sea surface temperature, surface emissivity, all-wave net radiation, and sensible and latent heat fluxes. Some challenges, and outlook such as virtual constellation of different satellite sensors, temporal homogeneity tests of long time-series products, algorithms ensemble, and products intercomparison are also discussed.

“…Recently, Song et al [17] released a long-term record of TOA albedo over land generated from AVHRR data, which provides the longest continuous record of global satellite observations since 1981. Direct estimation models were built to derive instantaneous TOA broadband albedo.…”

“…The differences between DEEP-C and CM SAF in Europe and Africa, however, were much smaller. As some overestimations and underestimations in these datasets are seasonally dependent and can be removed following the deseasonalizing process [17], some differences may not be shown in this figure. Therefore, we also calculated the absolute value of the DEEP-C, TAL-AVHRR, TAL-MODIS, CERES, and CM SAF monthly mean TOA albedo for different regions.…”

“…Estimation of TOA albedo from remote sensing data is a unique means to generate TOA albedo products at regional or global scales. Different algorithms have been proposed to estimate TOA albedo from satellite data, and multiple TOA albedo products from both broadband and narrowband sensors have been developed [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17], some of which have a relatively high spatial resolution that is helpful in studying the energy budget at regional scales [15][16][17].…”

Song et al [17] developed a long-term record of TOA albedo over land from Advanced Very High Resolution Radiometer (AVHRR) data (TAL-AVHRR) and compared it to both CM SAF and CERES data. However, no study has systematically compared all five products.…”

Five satellite top-of-atmosphere (TOA) albedo products over land were evaluated in this study including global products from the Advanced Very High Resolution Radiometer (AVHRR) (TAL-AVHRR), Moderate Resolution Imaging Spectroradiometer (MODIS) (TAL-MODIS), and Clouds and the Earth's Radiant Energy System (CERES); one regional product from the Climate Monitoring Satellite Application Facility (CM SAF); and one harmonized product termed Diagnosing Earth's Energy Pathways in the Climate system (DEEP-C). Results showed that overall, there is good consistency among these five products, particularly after the year 2000. The differences among these products in the high-latitude regions were relatively larger. The percentage differences among TAL-AVHRR, TAL-MODIS, and CERES were generally less than 20%, while the differences between TAL-AVHRR and DEEP-C before 2000 were much larger. Except for the obvious decrease in the differences after 2000, the differences did not show significant changes over time, but varied among different regions. The differences between TAL-AVHRR and the other products were relatively large in the high-latitude regions of North America, Asia, and the Maritime Continent, while the differences between DEEP-C and CM SAF in Europe and Africa were smaller. Interannual variability was consistent between products after 2000, before which the differences among the three products were much larger.
