Today at 16:55 UTC, NOAA decommissioned NOAA-19, the most recently launched of the remaining legacy NOAA POES spacecraft. NOAA-19 launched on February 6th, 2009 and become operational on June 2nd, 2009. For the last 16 years, NOAA-19 has provided routine weather observations of the entire globe from low-earth orbit.<\/p>\n\n\n\n

The AVHRR visible\/IR imager and AMSU-A\/MHS set of microwave sounders were both functioning well on NOAA-19 in its final days. However, due to a spacecraft battery failure on August 9th, the decision was made to accelerate the decommissioning timeline by about 6 days. The HRPT direct broadcast system on the spacecraft started to falter on August 11th, so the final daytime overpass of Wisconsin by NOAA-19 (with valid science data) was received by SSEC’s Madison antenna at 15:56 UTC on August 10th. Below is a selection of the AVHRR Level 1 imagery from that pass, along with AVHRR Level 2 Sea Surface Temperature retrievals from CSPP ACSPO<\/a>, and AMSU-A\/MHS Level 2 Total Precipitable Water and Rain Rate products from CSPP MiRS<\/a>.<\/p>\n\n\n\n

Today’s activity follows NOAA-18’s decommissioning on June 6th<\/a>. NOAA-15, the last operating spacecraft in the POES series, is slated to be turned off during the week of August 18th. <\/p>\n\n\n\n
