Visible image of JMA/GMS5 taken from a geostationary orbit about 36,000 km above the equator.
The images are taken on a half-hourly basis.
Dark areas in a visible image represent geographic regions were small amounts of visible light from
the sun are reflected back to space. Whiter regions are objects that are highly reflective.
The oceans are usually dark while snow and thick clouds are bright. Therefore visible
satellite imagery is restricted to daylight hours.
However, the best method to interpret satellite images is to view visible and infrared imagery together.
