This table identifies the NOAA satellites that carried the AVHRR during the period of interest to the Leads ARI. The figure also indicates the approximate times of the ascending and descending nodes in Local Solar Time (LST). An ascending node implies a northbound equatorial crossing while a descending node implies a southbound equatorial crossing.
Satellite Launch Ascending Descending Service Number Date Node Node Dates NOAA-9 12/12/84 1420 0220 02/25/85 - 11/07/88 NOAA-10 09/17/86 1930 0730 11/17/86 - Inactive NOAA-11 09/24/88 1340 0140 11/08/88 - 09/13/94 NOAA-12 05/14/91 1930 0730 05/14/91 - Present
