High albedo surfaces
WebHá 2 dias · In March 2024, snow albedo averaged over the western United States was strikingly high relative to the 23-year satellite record (Figure 3, left). This is the result of new snowstorms depositing new fine grain snow over older, larger snow grains and dust or soot on the snow surface. Thus, the new fresh snow has a high snow albedo. Web13 de abr. de 2024 · Snow cover plays a critical role in terrestrial hydrological, climatological, and ecological processes. It influences the energy balance on the land surface, based on its high albedo and low thermal conductivity . The measurement of snow water equivalent (SWE) is important to understand the timing and magnitude of snowmelt runoff .

Webhave very high albedo, as high as 0.8 or 0.9, and reflect most of the solar energy that gets to them, absorbing very little. The albedo of all these different surfaces combined is called the planetary albedo. Earth's planetary albedo is about 0.31. That means that about a third of the solar energy that gets to Earth WebThe CLARA surface albedo (SAL) is a global covered 28-year time series (1982–2009) of Earth’s black-sky surface albedo product (Riihelä et al., 2013b ), which was generated with advanced very high-resolution radiometer (AVHRR) top of atmosphere (TOA) data.
Web19 de nov. de 2024 · Surface albedo (from the Latin word albus, which means white) is the measure of diffuse reflection of solar radiation from the ground back to space of incidence. It is dimensionless and measured on a scale from 0 (a black surface that absorbs all radiation) to 1 (a surface that reflects 100% of received radiation to space of incidence).
