Images from the limb

Ever wonder why some imagery looks nice and other looks blotchy (for lack of a better word). The difference is where the cyclone is with respect to the satellite.

The following demonstrates the difference between a satellite that is “close by” and one that is barely visible.

A full constellation of about 5 geostationary satellites are needed to observe the entire Earth (except at the poles). Often, some points on Earth are visible from multiple satellites. In some cases, these views can be very oblique. But thanks to the highly machined telescope mirrors, the imagery at these grazing angles might still be used. If you have a limb observation and can still discern the cloud structure around the storm, then please do so. If the image is skewed beyond understanding then click “Other → Edge”
