Materials that can give a city or planet a high reflectivity or albedo include light-colored surfaces such as white paint, concrete, or light-colored stones. Metals like aluminum and silver also have high reflectivity. Additionally, smooth surfaces like glass or mirrors can also contribute to higher reflectivity.
From NOAA website:http://weather.noaa.gov/radar/radinfo/radinfo.htmlBase ReflectivityThis is a display of echo intensity (reflectivity) measured in dBZ (decibels of Z, where Z represents the energy reflected back to the radar). "Reflectivity" is the amount of transmitted power returned to the radar receiver. Base Reflectivity images are available at several different elevation angles (tilts) of the antenna and are used to detect precipitation, evaluate storm structure, locate atmospheric boundaries and determine hail potential.The base reflectivity image currently available on this website is from the lowest "tilt" angle (0.5°). This means the radar's antenna is tilted 0.5° above the horizon.The maximum range of the "short range" (S Rng) base reflectivity product is 124 nm (about 143 miles) from the radar location. This view will not display echoes that are more distant than 124 nm, even though precipitation may be occurring at greater distances. To determine if precipitation is occurring at greater distances, select the "long range" (L Rng) view (out to 248 nm/286 mi), select an adjacent radar, or link to the National Reflectivity Mosaic.Composite ReflectivityThis display is of maximum echo intensity (reflectivity) from any elevation angle at every range from the radar. This product is used to reveal the highest reflectivity in all echoes. When compared with Base Reflectivity, the Composite Reflectivity can reveal important storm structure features and intensity trends of storms.The maximum range of the "long range" (L Rng) composite reflectivity product is 248 nm (about 286 miles) from the radar location. The "blocky" appearance of this product is due to its lower spatial resolution on a 2.2 * 2.2 nm grid. It has one-fourth the resolution of the Base Reflectivity and one-half the resolution of the Precipitation products.Although the Composite Reflectivity product is able to display maximum echo intensities 248 nm from the radar, the beam of the radar at this distance is at a very high altitude in the atmosphere. Thus, only the most intense convective storms and tropical systems will be detected at the longer distances.Because of this fact, special care must be taken interpreting this product. While the radar image may not indicate precipitation it's quite possible that the radar beam is overshooting precipitation at lower levels, especially at greater distances. To determine if precipitation is occurring at greater distances link to an adjacent radar or link to the National Reflectivity Mosaic.For a higher resolution (1.1 * 1.1 nm grid) composite reflectivity image, select the short range (S Rng) view. The image is less "blocky" as compared to the long range image. However, the maximum range is reduced to 124 nm (about 143 miles) from the radar location.

Reflectivity in radar is measured using the returned power of the radar signal after it interacts with precipitation or other targets in the atmosphere. This power is typically expressed in decibels (dBZ) and relates to the size, shape, and concentration of the particles. The radar system emits a pulse, and by calculating the intensity of the echo received after the pulse bounces off targets, meteorologists can determine the reflectivity, which helps in estimating precipitation intensity and type.
The higher the reflectivity of an object, the more intense and defined its highlights will appear. Objects with low reflectivity will have softer and less pronounced highlights. Reflectivity influences how light interacts with the surface of an object, affecting the appearance of highlights.
Emissivity and reflectivity are inversely related properties of materials. Emissivity refers to how well a material emits thermal radiation, while reflectivity refers to how well it reflects thermal radiation. A material with high emissivity will have low reflectivity, and vice versa.
The property that reflects light is called reflectivity. This is the measure of how well a surface reflects light and is often described in terms of its reflectance or albedo. Smooth, shiny surfaces tend to have high reflectivity, while rough or dark surfaces have low reflectivity.
The mirror reflectivity affects the quality of the reflected image by determining how much light is reflected back. Higher reflectivity mirrors produce clearer and brighter images, while lower reflectivity mirrors may result in dimmer and less sharp images.
albedo
The relationship between metal reflectivity and its ability to efficiently reflect light is direct. Higher metal reflectivity means the metal is better at reflecting light efficiently.
Reflectance refers to the amount of light that is reflected off a surface, while reflectivity is a measure of how efficiently a surface reflects light. Reflectance is a property of the surface, while reflectivity is a physical property of the material. In the context of light and surface interactions, reflectance and reflectivity are related in that they both describe how much light is reflected off a surface, but reflectivity specifically quantifies the efficiency of that reflection.
Materials that can give a city or planet a high reflectivity or albedo include light-colored surfaces such as white paint, concrete, or light-colored stones. Metals like aluminum and silver also have high reflectivity. Additionally, smooth surfaces like glass or mirrors can also contribute to higher reflectivity.
"What are the duties and responsibilities of a researcher?"
Albedo
The plural possessive of researcher is researchers'.
The reflectivity of a mirror affects its ability to produce clear and sharp images by determining how much light is reflected back to the viewer. A mirror with high reflectivity will produce a clearer and sharper image because it reflects more light, resulting in a brighter and more detailed reflection. Conversely, a mirror with low reflectivity will produce a dimmer and less detailed image.
