what does an albedo of 1.0 mean ??
An albedo of 1.0 means that 100% of the light that hits the planet (or other object) is reflected away.
Areas with a white cloud cover or newly fallen snow have an albedo of nearly 1.0
drwls thank you
An albedo of 1.0 means that an object or surface reflects all of the incoming light that hits it, and absorbs none. In other words, it is a perfect reflector of light. To understand the concept of albedo, you need to measure the amount of light reflected by an object or surface relative to the amount of light it receives. To determine the albedo of something, you can follow these steps:
1. Measure the amount of incoming light: Use a light meter or a similar device to measure the intensity of the light hitting the object or surface you want to investigate.
2. Measure the amount of reflected light: Place a reflective surface next to the object or surface you are measuring and measure the intensity of the reflected light using the same method as before.
3. Calculate the albedo: Divide the intensity of the reflected light by the intensity of the incoming light. This will give you a decimal value between 0 and 1. A value of 0 means that no light is reflected (albedo of 0), while a value of 1 means all light is reflected (albedo of 1).
In practical terms, an object or surface with an albedo of 1.0 appears very bright because it reflects all of the light that falls onto it. Snow and some types of clouds are examples of natural substances that have high albedo, reflecting most of the sunlight that reaches them.
