Stretched vissr data
From Glossary of Meteorology
stretched VISSR data
GOES VISSR image data that have been stretched in time by the temporary storage and retransmission of those data.
The data rate of the VISSR data is reduced from 28 Mbits per second to 2 Mbits per second, allowing ground station users to receive the data more easily. Since the launch of GOES-8, stretched VISSR data have been replaced by GVAR data.
