Interpreting Satellite Images

The radiometers flown on satellites are not cameras. Moving mirrors make the radiometer view different regions of the earth. The instrument begins by looking off in one direction and then scans across a scene making observations as it proceeds. In this manner the radiometer scans a scene line-by-line. Data is recorded in a two-dimensional format (line and element) which, when displayed on a computer monitor or television screen, makes up an image.

Universal Coordinated Time and Zulu Time

The satellite images that appear on NOAA's Web sites are stamped in Zulu time. To make the conversion to your local time, see the chart below. Find your local time in the first column. If you are on Eastern Daylight Saving Time (EDT), you would use the second column to find your Zulu Time/UTC. For instance, if it's 11 a.m. Latitude/Longitude Distance Calculator.


Meteorological Calculations and Conversions. SSEC - FAQ. The majority of satellite imagery that SSEC focuses on, such as GOES, NOAA polar satellites, Aqua/Terra, etc., is geared towards viewing Earth's meteorology, oceanography and climate and does not have the spatial resolution to see things like people or cars.


For example, the MODIS instrument on the Aqua and Terra satellites has a resolution of 250 meters which means that it can't resolve anything smaller than that. However, the WisconsinView organization which operates here at SSEC does work with high resolution satellite imagery that could be of use for observing smaller scale objects/places on the ground. Specifically, WisconsinView maintains a free online archive of civilian public domain color satellite imagery and aerial photos of Wisconsin with spatial resolutions ranging from 15cm (6-inch) to 250m (273yds).
