NOAA-4, also known as ITOS-G was a weather satellite operated by the National Oceanic and Atmospheric Administration (NOAA). [4] It was part of a series of satellites called ITOS, or improved TIROS. [5] NOAA-4 images of cyclone Tracy. NOAA-4 was launched on a Delta rocket on November 15, 1974.

NOAA 4 (ITOS-G) was one in a series of improved TIROS-M satellites launched with new meteorological sensors on board to expand the operational capability of the ITOS (NOAA) system. The primary objective of the ITOS-G meteorological satellite was to provide global daytime and nighttime direct readout cloudcover data on a daily basis.

In Week 3, above normal heights are favored over the eastern CONUS, while in Week 4, the above normal heights shift westward. This leads to broad weakly above normal heights in the Weeks 3-4 period that stretch across the CONUS in GEFSv12 and ECMWF.
