Atmospheric Emitted Radiance Interferometer AERI

Equipment Required

• Large phillips screwdriver
• Small phillips screwdriver
• Ball driver set
• 3rd Blackbody
• 3rd Blackbody breakout cable

Procedure

Hardware setup

1. Power OFF the instrument using the power bar in the AERI back-end
2. Remove the front panel and the front-end enclosure from the AERI front-end (see instructions here)
   • Verify that the interior fan power cable is disconnected
3. Remove the sky view aperture plate (four #8 hex screws) (Fig. 1).
4. Locate the 3rd blackbody and remove the red protective aperture cover (Fig. 2).
5. Connect the “3rd body” connector on the 3rd blackbody breakout cable to the 3rd blackbody.
6. Install the 3rd blackbody onto the sky view port (in place of the sky view aperture plate) (see Fig. 3)
   • Attach the 3rd blackbody with 2-4 screws – but do not tighten yet
   • Push the 3rd blackbody up against the optical alignment buttons on the back of the sky view port so that it’s optically registered
   • Tighten the screws to secure the 3rd blackbody
7. Connect the 3rd blackbody breakout cable (Fig. 3)
   • Disconnect the ABB connector from the ABB
   • Connect the ABB connector into  “ABB Connector” on the breakout cable
   • Connect the “ABB” connector on the breakout cable to the ABB
8. Connect the ABB SP cable to the ABB blackbody controller board connector on the AERI back-end (Fig. 4)
9. Power ON the instrument

Software setup

10. Stop data collection on the AERI
    • Press ctrl-c up to 3 times in the black Cygwin window to terminate ingest, then close the FTSW window
11. Manage the data directories
    • Rename c:\AEYYMMDD, where YYMMDD is the current date (e.g. c:\AE210228)
      • cd /cygdrive/c
      • mv AEYYMMDD AEYYMMDDA
    • Rename c:\ftp\AEYYMMDD, where YYMMDD is the current date (e.g. c:\ftp\AE210228)
      • cd /cygdrive/c/ftp
      • mv AEYYMMDD AEYYMMDDA
    • Delete (or rename) the contents of c:\temp, carefully double-check the correct path to avoid accidentally deleting something else
      • cd /cygdrive/c/temp
      • rm *
      • (or mv temp tempA to continue afterward where ingest left off)
    • Delete c:\E-AERI\Data\HouseKeeping.hk, if it exists
      • cd /cygdrive/c/E-AERI/Data
      • rm HouseKeeping.hk
12. Change to 3rd body breakout configuration
    • cd \\config
    • change_config_to 3body_breakout
    • cat mirror.beg (to verify new correct mirror program is selected)
13. Change FTSW configuration file
    • Open the file c:\E-AERI\FTSW_EAERI.Config
    • Set calibKitY.connected = true
    • Save the file
14. Run FTSW_EAERI_GUI.bat
    • The software detects modification of the configuration file (see Fig. 8).  Click OK to start FTSW in calibration mode
    • Select the blackbody coefficient file for the 3rd blackbody
    • Verify that ref1 Blackbody is displayed in FTSW and heating and stabilized at the correct temperature (Fig. 9)
      • The default setting is 45°C, and the blackbody heats at a rate of ~1°C/min
    • Exit FTSW

Running the test

15. Run Ingest.bat to start the 3rd blackbody test
    • Run for at least 1.5 hours
16. To terminate the test, press ctrl-c up to 3 times in the black Cygwin window, and close the FTSW window

Software packup

17. Manage the data directories
    • Rename c:\AEYYMMDD, where YYMMDD is the current date (e.g. c:\AE210228)
      • cd /cygdrive/c
      • mv AEYYMMDD AEYYMMDD_3body
    • Rename c:\ftp\AEYYMMDD, where YYMMDD is the current date (e.g. c:\AE210228)
      • cd /cygdrive/c/ftp
      • mv AEYYMMDD AEYYMMDD_3body
    • Delete (or rename) the contents of c:\temp, carefully double-check the correct path to avoid accidentally deleting something else
      • cd /cygdrive/c/temp
      • rm *
      • (or mv tempA temp to continue afterward where ingest left off)
    • Delete c:\E-AERI\Data\HouseKeeping.hk
      • cd /cygdrive/c/E-AERI/Data
      • rm HouseKeeping.hk
18. Change to normal science configuration
    • cd \\config
    • change_config_to RS_3
    • cat mirror.beg (to verify new correct mirror program is selected)
19. Change FTSW configuration file
    • Open the file c:\E-AERI\FTSW_EAERI.Config
    • Set calibKitY.connected = false
    • Save the file
20. Send the directory c:\ftp\AEYYMMDD_3body to the mentor team for analysis

Hardware packup

21. Power OFF the instrument
22. Disconnect the ABB SP cable from the ABB blackbody controller board connector on the AERI back-end (Fig. 4)
23. Disconnect the 3rd blackbody breakout cable
    • Reconnect the ABB connector to the ABB
24. Uninstall the 3rd blackbody
