It looks like the HIRS instrument is back to normal. Channel 7 returned
to normal after the level 1B pass B1952324. However, the HIRS 24-hour
calibration file must be re-initialized to get rid of bad data. This
will be done over the next 24-hours. Assuming the HIRS instrument
continues to function properly, we expect to have a good update sometime
Thank you for your support.
