This is the AIRS, AMSU-A, and HSB weekly operations status report for Friday, November 29, 2024 (the end of week 1177 of the Aqua mission).
Please note the list of AIRS channels with upcoming gain changes.

 
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.


Instrument activities since previous report:

   There were no instrument activities this past week.
  

Upcoming events:

1) A new Optimum (normal operations) gain & circumvention table will be uploaded.
The table has been generated.  Here is a list of channels whose A/B weights will change in the new table.  Weather and L2 channels are noted.

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/.
