The Antarctic composites are a mosaic of GOES, Meteosat, GMS, DMSP and NOAA satellite data, and are updated every three hours, thus creating eight pictures per day. The Antarctic composite may have regions that are blacked out or look gray in color. These areas of black or gray space, other than the latitude and longitude lines and continent outlines, indicate missing imagery or a lack of satellite coverage.

Infrared Antarctic Composites

• The most recent color enhanced, low resolution (20 kilometer) infrared Antarctic composite image (~160 Kb).

• The latest mid-resolution (10 kilometer) infrared Antarctic composite image (~325 Kb).

• The latest full resolution (5 kilometer) infrared Antarctic composite image (~650 Kb).

• New!The latest mid-resolution (10 kilometer) Synoptic Chart with synoptic observations, ship and buoy observations, GFS model analysis of mean sea level pressure (isobars) over our Antarctic composite image (~1 Mb).

• New!The latest mid-resolution (10 kilometer) infrared psuedo-color Antarctic composite image (~1 Mb).

  The pseudo-color Antarctic composite is created by estimating a cloud/no cloud threshold with the infrared Antarctic composite satellite raw data and overlaying the results on a color background provided by the Earth Observatory Team - NASA (http://earthobservatory.nasa.gov). The algorithm was developed by Rick Kohrs, SSEC, UW-Madison.

Water Vapor Antarctic Composites

• The most recent low resolution (20 kilometer) water vapor Antarctic composite image (~160 Kb).

• The latest mid-resolution (10 kilometer) water vapor Antarctic composite image (~325 Kb).

• The latest full resolution (5 kilometer) water vapor Antarctic composite image (~650 Kb).

Visible Antarctic Composites

• The most recent low-resolution (20 kilometer) visible experimental Antarctic composite image (~325 Kb).

• The most recent high-resolution (10 kilometer) visible experimental Antarctic composite image (~325 Kb).

• The most recent full-resolution (5 kilometer) visible experimental Antarctic composite image (~325 Kb).
