Anomalies • GOME-2 • GOME-2 has experienced a series of anomalies related to spurious EQSOL signals. The signals may originate in the instrument, line or source. • The anomalies occur when the satellite is in the South Atlantic Anomaly. • The cause at this point is not known. The association with the SA Anomaly suggests SEUs. A workaround may involve implementing a fast recovery cycle.
Anomalies (Cont.) • Data Dropouts • MHRPT data nominal • GDS data anomaly • All instrument affected – Not just AMSU-A1 & A1 • Ground tracking receiver problem • Workaround implemented • Minimize/eliminate dropouts
Anomalies • NOAA AMSU-A 1B • Initial AMSU-A1 & -A2 1B data did not contain calibration coefficients • Cause by a s/w error • Problem identified and corrected by OSDPD, Friday October 27 • All AMSU-A1 & -A2 data following well
