Agricultural and Forest Meteorology, 211–212, 23-36, [3]Jiang, B., Liang, S., Jia, A., Xu, J., Zhang, X., Xiao, Z., Zhao, X., Jia, K., & Yao, Y. Albedo is the measure of the diffuse reflection of solar radiation out of the total solar radiation and measured on a scale from 0, corresponding to a black body that absorbs all incident radiation, to 1, corresponding to a body that reflects all incident radiation. 2019), References:[1]Jia, K., Liang, S., Liu, S.H., Li, Y.W., Xiao, Z.Q., Yao, Y.J., Jiang, B., Zhao, X., Wang, X.X., Xu, S., & Cui, J. On the basis of the theory of light use efficiency, the EC-LUE model relies on two assumptions: first, that the fraction of absorbed PAR (fPAR) is a linear function of NDVI; second, that the realized light use efficiency, calculated from a biome-independent invariant potential LUE, is controlled by air temperature or soil moisture, whichever is most limiting. The surface albedo in winter is highly correlated with the snow cover extent in the Sanjiang Plain, and the increasing trend of surface albedo can be further enhanced by the land use changes.

Direct-estimation algorithm for mapping daily land-surface broadband albedo from MODIS data. The BaseColor/Albedo are the same and referring to a PBR workflow, whereas the Diffuse means the 'old' non-PBR workflow. 2018). Specifying a single color for the Albedo value is sometimes useful, but it is far more common to assign a texture map for the Albedo parameter. 2.1.4.

Human-induced landcover changes drive a diminution of land surface albedo in the Loess Plateau (China). (2018). Evaluation of Three Long Time Series for Global Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) Products. 2017). At the same time, we developed an efficient hybrid method for estimating 1 km instantaneous clear-sky LWDN from MODIS TIR observations and the MODIS near-infrared column water vapor (CWV) data product(Cheng et al. Integrating the empirical glass reflectance function and non-crystalline solids reflectance values over the dayside surface of the exoplanet at secondary eclipse yields an upper limit for the albedo of a lava-quenched glass planet surface of $\sim $0.1. Validation of Global LAnd Surface Satellite (GLASS) fractional vegetation cover product from MODIS data in an agricultural region. (2015a). For vegetated surfaces, we estimate the BBE by constructing a look-up table (LUT) based on the 4SAIL radiative transfer model(Cheng et al. Hydrology and Earth System Sciences, 17, 2121-2129, doi:2110.5194/hess-2117-2121-2013, [2]Liu, Q., Wang, L., Qu, Y., Liu, N., Liu, S., Tang, H., & Liang, S.

To meet these requirements, GLASS (Global LAnd Surface Satellites) gapless albedo product from 1981 to 2010 was firstly released in 2012 and widely used in long-term earth change researches. Broadband Albedo (Albedo) The GLASS albedo products include three spectral ranges: total shortwave, visible and near-IR under actual atmospheric conditions (so-called blue-sky albedos).

The product of these values indicates a difference in average albedo for the whole earth of 0.017. 2018). 2018). 2019), and using GLASS LST and BBE product to calculate clear sky LWUP. Chin. This algorithm takes advantage of both ASTER BBE and MODIS shortwave albedo products,as well as the established non-linear relationship between ASTER BBE and seven MDOSI spectral albedos. 20000201 20000301 20000401 20000501 20000601 20000701 20000801 20000901 20001001 20001101 20001201 20010101 20010201 20010301 20010401 20010501 20010601 20010701 20010801 20010901 20011001 20011101 20011201 20020101 20020201 … doi: https://doi.org/10.1175/2011JCLI3946.1, Essery R, 2013.

Re: List of reflectance / albedo of common materials Quote from: Juraj_Talcik on 2014-03-07, 00:53:15 I am more afraid people might just put that … Their BBE is assumed to be their average values. White objects, such as a snowy hill have a high albedo. The GLASS DSR (V1.0) was developed based on an improved LUT method using multiple polar-orbiting and geostationary satellite data (Zhang et al. Remote Sensing of Environment, 171, 105-117, [2]Xiao, Z., Liang, S., & Sun, R. (2018). A rank-invariant method of linear and polynomial regression analysis. (2013). Albedo is the amount of sunlight (solar radiation) reflected by a surface, and is usually expressed as a percentage or a decimal value, with 1 being a perfect reflector and 0 absorbing all incoming light. Background Research: Albedo is the reflecting power of a surface. doi: https://doi.org/10.1002/ppp.445, Liu J Y, Liu M L, Deng X Z et al., 2002. - 66.70.227.184. glass dome of the pyranometers) and the reflection proper- ties of the sensor’s black paint, the latter is also noted by Muneer(1997), leading to an overestimation of albedo.

The Global Land Surface Satellite (GLASS) Product suite has been expanded from the original five products (Liang, et al., 2013a,b) to the current 14 products: Leaf Area Index (LAI), Broadband Albedo (Albedo), Broadband Emissivity (BBE), Fraction of Absorbed Photosynthetically Active Radiation (FAPAR), Downward Shortwave Radiation (DSR), … Journal of Geographical Sciences, 24(5): 789–801. Overview of the GLASS products . 2014) . Climatic Change, 137, 363-377, [3]Chen, X., Long, D., Hong, Y., Liang, S., & Hou, A. As mentioned earlier, an ideal blackbody will absorb all incident light, but in the real world, things absorb only part of the incident light. Recent efforts have extended to include sea ice (Qu et al. Hollow glass microspheres (HGMs) are promising materials for arctic ice restoration. A perfect reflector would have an albedo of 1, whereas a perfect absorber would have an albedo of 0. IEEE Journal in Special Topics in Applied Earth Observations and Remote Sensing, 3, 323-336, [3]Cheng, J., & Liang, S. (2014). Wetlands, 29(1): 302–313. The purpose of this paper is to assess the quality of the Global Land Surface Satellite (GLASS) albedo products, which are being generated in China under the 863 key project entitled “Generation and Applications of Global Products of Essential Land Variables”. The GLASS FAPAR product from MODIS data is the instantaneous value at 10:30 am local time, close approximation of daily average PAPAR. Journal of Applied Remote Sensing, 8(1): 083532. doi: https://doi.org/10.1117/1.JRS.8.083532, Gelaro R, McCarty W, Suárez M J et al., 2017. The long-term GLASS FAPAR product was also compared with two similar products and shows high quality and accuracy (Xiao et al. The term 'albedo' describes the proportion of incident radiation reflected by a system. To accurately indicate the long-term changes of GPP, the GLASS-GPP product used the latest version of EC-LUE, which integrates the impacts of several environmental variables: atmospheric CO2 concentration, radiation components and atmospheric water vapor pressure (VPD) (Yuan et al., in preparation). The fraction of light that is reflected by an object is called the albedo, which means whiteness in Latin. I need to know how much the albedo is for glass or plastic Ieee Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 12, doi:10.1109/jstars.2018.2854293, [5]Yang, L., Jia, K., Liang, S., Liu, J., & Wang, X. But at the end, all maps are the same. 2014). Estimating the fraction of absorbed photosynthetically active radiation from the MODIS data based GLASS leaf area index product.

(2013). Unlike existing neural network methods that use only remote-sensing data acquired at a specific time to retrieve LAI, the preprocessed MODIS reflectance data (Tang et al. Long-time series and various spatial resolution albedo products are needed for climate change and environmental studies at both global and regional scale. This result indicates the possibility of improving the albedo by adopting the white foam glass as a reflecting surface layer. doi: https://doi.org/10.1002/2014JD021667, Hu Y H, Jia G S, Pohl C et al., 2016. BBEs of water and snow or ice were set to 0.985 based on a combination of BBE calculated from the emissivity spectra in the ASTER spectral library and the MODIS UCSB spectral library, and BBE values simulated using radiative transfer model (Cheng et al. 2014), the multivariate adaptive regression splines (MARS) model was selected as the GLASS net radiation product algorithm. The GLASS Land Surface Temperature Product. The average reflectances of the white foam glass and commonly used gravel were 48.3 and 10.7%, respectively, in the region between 300 and 1100 nm. A Cloud Detection Method Based on Time Series of MODIS Surface Reflectance Images. Chinese Geographical Science 2014). Ben is 19. Surface albedo is defined as the ratio of radiosity to the irradiance received by a surface. Advanced Remote Sensing: Terrestrial Information Extraction and Applications.
