This is the AIRS, AMSU-A, and HSB weekly operations status report for Friday, December 29, 2023 (the end of week 1130 of the Aqua mission).

 
AIRS:  The AIRS instrument remains healthy with all voltages, currents, and temperatures as expected.
AMSU-A1:  AMSU-A1 is healthy except for channels 4, 5, 6, and 7.
AMSU-A2:  AMSU-A2, which provided channels 1 and 2 of the AMSU-A suite, suffered a non-recoverable loss of power on September 24, 2016 and is no longer operational.
HSB:  HSB has been non-operational since February 2003 due to a scanner anomaly.

Daily plots of noise levels for each AIRS channel are available on the AIRS webpage at https://airs.jpl.nasa.gov/mission/instrument-operations/.
A link there currently points to where the files are hosted at https://thunder.jpl.nasa.gov/nedt_trends/html/airs_channel_nedt_trends.html.
For each channel there are plots for the whole AIRS mission and for the last 2 months.
Going forward, weekly Ops status updates will be archived at the same webpage above,
and are hosted at https://airsteam.jpl.nasa.gov/report/latest and https://airsteam.jpl.nasa.gov/report/archive/.
