Note on Pause in Daily Readings

Readings of CO2 from Mauna Loa have been unavailable for two weeks.

According to technicians with the Scripps CO2 Group, the problem is a disk failure that handles the data buffering, which has broken the data stream and valve switching that impacts daily calibration.  The air data are recoverable, because the computer onboard the actual instrument is still working and taking air data, but we will need to assess the stability of calibration once the instrument is working completely again.  A replacement was shipped last week, so it should be up again shortly.
