This is the AIRS, AMSU-A, and HSB weekly operations status report for Friday, July 26, 2024 (the end of week 1160 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.


Instrument activities since previous report:

An AIRS OBC float calibration test started yesterday, Thursday, July 25.  The test will conclude tomorrow, Saturday, July 27. Here is the timeline (UT):

207/17:00   Set AIRS opmode to READY
207/17:00   Load calibration gain table to AIRS
207/17:01   Turn OBC heater off
209/04:20   Rotate scan profile to OBC
209/04:45   Rotate scan profile to nadir
209/05:00   Turn OBC heater on
209/21:00   Load Optimum (nominal) gain table to AIRS
209/21:01   AIRS back in OPERATE mode

Upcoming events:

1) An AIRS photometric calibration test is planned for Wednesday, August 7.  This activity has not been scheduled yet.

2) A new Optimum (normal operations) gain & circumvention table will be uploaded.
The upload has not been scheduled yet.


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/.
