This is the AIRS, AMSU-A, and HSB weekly operations status report for Friday, November 10, 2023 (the end of week 1123 of the Aqua mission). Instrument status: 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 photometric calibration test ran on Tuesday, November 7. Here is the detailed timeline (UT): 311/21:43:00 Photocal Lamp 3 On (S/C night) 311/21:51:00 Photocal Lamps Off (S/C night) 311/22:32:00 Photocal Lamp 3 On (S/C day) 311/22:40:00 Photocal Lamps Off (S/C day) AIRS hardware state: (any changes since previous report are in bold) AIRS Quiet Bus A on AIRS Noisy Bus A on AIRS Survival Bus A on AIRS Quiet Bus B off AIRS Noisy Bus B on AIRS Survival Bus B on Decontamination heater A off Decontamination heater B off Group 2 power on Detector gain tables Optimum gains loaded---Table PM1_ISC_AIR_450_air_gnc_o190919_0 first loaded on October 7, 2019 and effective at approximately 23:18 UT Radiometric calibrator heater on Choke point heater enabled with a set point of 155.56 K Scanner uncaged; scanning using nominal profile Cooler A uncaged, electronics on, compressor on, cold head set point 56.47 K Cooler B uncaged, electronics on, compressor on, cold head set point 56.47 K Focal plane detector modules on Circumvention processing on AIRS software state: Patches: version 11 loaded Macros: version 17 loaded EDC tables: alternates #1, #2, and #4 loaded, nominal EDC table active TMON's: active OpMode: "OPERATE" Op submode: "0" CalFunc bits: All zeroes AMSU-A hardware state: AMSU-A1: On; scanners in full scan mode. Selected space view is #3. Channel 7 has not met noise specifications since launch. Channel 4 was declared non-operational in November 2007 and channel 5 became too noisy to use in early 2013. Channel 6 NeDT is now greater than 1K. Version 5 of the AIRS science software did not use Channel 4 and Version 6 uses neither channel 4 nor channel 5. AMSU-A2 (Channels 1 and 2): Off (survival mode). Receiver temperature is about -10° C, Scan Motor temperature is about -4° C. HSB hardware state: Off (survival mode); scanner stopped at about scan position 38 (about 8 degrees off nadir). TMON 51, which turns on the survival heater at -15 degrees C, is enabled. TMON 52, which turns off the survival heater at 0 degrees C, is disabled. The survival heater is off. Local Oscillator temperatures have stabilized at about +15° C. Upcoming events: 1) The special AIRS calibration tests are scheduled for November 13 - 15.

This activity has not been scheduled yet. 3) MODIS Lunar Calibration #225 is planned for Friday, November 24. The timeline for this activity will appear in next week's report. 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/. ================================================================== William Mathews - AIRS Instrument Operations NASA / Jet Propulsion Laboratory
