Explanation: Albedo is the measure of the reflectivity of a material. A high albedo means it reflects a lot of light and a low albedo means it absorbs a lot of light. An example of a high albedo material is snow and ice.
WebEarth receives energy from the Sun and radiates back to space an equal amount. What statement below accurately describes how this occurs? The energy that is not reflected directly back to space is radiated back at longer wavelengths in the infrared portion of electromagnetic spectrum. Webthe input wavelet is a minimum phase: (a) earth reflectivity series convolved with a 4/8 - 150/250 Hz zero-phase bandpass filter; (b) earth reflectivity series convolved with a minimum phase wavelet, given by exp(-0.15t)sinOT t/20) (This is the input trace to the following deconvolution process); (c) result of the spiking deconvolution with a
WebReflectivity is the capacity of an object to reflect solar radiation. It is described as a function of radiation wavelength and is determined by the physical composition of the object. The adjective “spectral” is frequently used in conjunction with reflectivity to indicate that reflectivity varies as a function of solar wavelength.
