This summer 2023, NOAA-21 VIIRS Near-Constant Contrast (NCC)<\/a> imagery has become available for National Weather Service (NWS) users to access in the Advanced Weather Interactive Processing System – II (AWIPS-II) via the Satellite Broadcast Network (SBN). With the addition of NOAA-21 VIIRS NCC, users can now access the nighttime visible imagery from three JPSS polar-orbiting satellites: Suomi-National Polar-orbiting Partnership (S-NPP), NOAA-20 and NOAA-21.<\/p>\n\n\n\n

Refer to the screenshot below that shows how users can access CONUS<\/a> VIIRS NCC imagery from all three satellites in AWIPS-II. In AWIPS, simply click on the ‘Satellite’ tab, scroll down to ‘SNPP and NOAA-20’, then to ‘S-NPP and NOAA-20 Near Constant Contrast’, and select ‘CONUS S-NPP and NOAA-20 NCC (0.7 um)’.  Be aware that the AWIPS menu entries are not updated with the NOAA-21 VIIRS NCC menus. The current menu configurations are planned to be updated in the next TOWR-S<\/a> RPM release, v24, tentatively scheduled for later this fall (~October 2023). However, users can update the NOAA-21 menu entries manually from the TOWR-S instructions that are described here<\/a>. The instructions also provide details on how to fix an overlap issue that may be seen between VIIRS satellite swaths. Note, per TOWR-S, the current menu configuration may not be applicable for other regions (e.g., Alaska sector) who receive VIIRS imagery from Direct Broadcast (DB).<\/p>\n\n\n\n

The animation below displays the VIIRS NCC imagery from all 3 satellites over CONUS during the overnight hours on 17 August 2023. The imagery is shown during the new moon phase of the lunar cycle. Notice how NOAA-21 VIIRS NCC imagery is placed in between NOAA-20 and SNPP VIIRS NCC imagery by 1\/4 orbit (~25 minutes apart).<\/p>\n\n\n\n

An AWIPS VIIRS NCC example from NOAA-21 observes the eye and areal extent of Hurricane Hilary. At ~0914Z, 19 August 2023, the hurricane was located southwest of the Baja California Peninsula<\/a>. The hurricane proceeded to move into Southern California the next day and produced significant precipitation totals over the region<\/a>.<\/p>\n\n\n\n
