Over the last 2 months, engineers have been trying various things to get the chopped motor unstuck. On Sun 7/20 the chopper motor began working again. After reviewing instrument information on Tue 7/22, the instrument was commanded to discrete mode, which allowed ozone measurements to resume. Processing was started on 7/23 on our parallel test system. Pull users can access the data via our DDSTEST system. Initial indications are that the data look reasonable, but after being shut off for 2 months, we must check the instrument calibration. If all looks good, we will resume production of N18 SBUV/2 ozone products on the operational system early next week.
