Why is there no imagery of the U.S. on Worldview for the current day?
Depending what time you access Worldview this is probably because the satellite has not yet passed over the country. You can look at previous days' imagery by using the date slider at the bottom of the screen.
What are the large data gaps or missing areas near the equator?
The regularly spaced gaps near the equator are due to lack of coverage between orbits. Terra, Aqua and Aura are polar orbiting satellites, traveling from pole to pole. The Terra satellite travels north to south, passing over the equator in the morning. Aqua and Aura move in the opposite direction, south to north, passing over the equator in the afternoon. At high latitudes, adjacent imaging swaths overap significantly but at the equator gaps occur between adjacent swaths. As a result, complete global coverage is achieved every one to two days. Geostationary satellites, such as weather satellites, do not move and remain pointed at one area of the Earth. As these satellites do not orbit the orbit the earth, they do not experience gaps, but they are also unable to provide global coverage.
Why are there so many clouds?
Approximately 70% of the earth's surface is covered by clouds at any given time. That means there is a good chance that the region you want to see will have some cloud cover. Use the time slider at the bottom of Worldview to view other dates.
What is GIBS?
The Global Imagery Browse Services (GIBS) are a set of standard services to deliver global, full-resolution satellite imagery in a highly responsive manner. GIBS currently serves LANCE NRT imagery and will be extended in 2013 to include MODIS science imagery from the beginning of the Terra and Aqua missions to present. Its goal is to enable interactive exploration of NASA's Earth imagery for a broad range of users.
