Question:

Why is there so much color variation among the Landsat browse images?

Answer:

A custom color stretch is performed on the images, based on individual scene content. Scenes from within the same area and/or acquisition date may vary in band content (due to differences such as cloud content or ground moisture). This differing content will cause variation in the results of the color stretch.

About

Landsat represents the world's longest continuously acquired collection of space-based moderate-resolution land remote sensing data. Four decades of imagery provides a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global change research. Landsat images are also invaluable for emergency response and disaster relief.
