|
An instrument malfunction occurred onboard Landsat 7 on May 31, 2003. The problem was caused by failure of the Scan Line Corrector (SLC), which compensates for the forward motion of the satellite. Subsequent efforts to recover the SLC were not successful, and the problem appears to be permanent. Landsat 7 data ceased to be acquired by ESA stations from that date.
Landsat 7 SLC-Off world-wide imagery continues to be acquired by USGS through the on-board tape recorder. Eurimage distributes the Level 1G Standard SLC-off product, containing the original data gaps, which gradually diminish in width toward the center of the scene. Standard Level 1G processing applies a small (2-pixel) interpolation along the scanline boundary, and all remaining duplicated image data are replaced with null values (zero-fill).

Landsat 5 |
Landsat 5 data has been regulalrly acquired at the ESA Matera station since 1 January 2004 (regular acquisitions at ESA stations had ceased on 30 June 2001). A set of Landsat 5 acquisitions at Matera from 26 June to 30 September 2003 is available from USGS archives.
