public class NOAA1bV4Reader
extends NOAA1bV3Reader

A NOAA 1b version 4 reader is similar to the 1b version 3 reader except that it accepts the version 4 in the archive and data headers. Version 4 started when the CLAVR-x cloud mask fill bytes were replaced with actual cloud mask information. Version 4 also has support for the Metop series of satellites.

Since:

3.2.1
