This video explains albedo - the concept that the brightness of the Earth system (atmosphere, ocean, and land surfaces) determines how much incoming solar energy is immediately reflected back to space. Reflected shortwave energy and land albedo... (View More)

Twice each day, once during daytime and once at sunset, students observe sky color, visibility, and sky conditions over a one week period. Each observation is recorded on a sky report form (included) for follow-up discussions and comparisons. This... (View More)
