1、Lessons Learned Entry: 1357Lesson Info:a71 Lesson Number: 1357a71 Lesson Date: 2003-07-16a71 Submitting Organization: GSFCa71 Submitted by: Bonita SeatonSubject: ADEOS-II NGN L0 Data Gap Introduction Problem Description of Driving Event: In early February 2003, JPL and NASDA reported gaps in Level 0

2、 data products received from the Wallops and Alaska ADEOS-II Data Processing Systems. Gaps in the SeaWinds product were characterized by JPL to be intermittent in nature, of variable size, and located at irregular intervals in the data products. Reprocessing of the raw data by NASDA yielded 100% dat

3、a recovery. Thus, while there was 100% data capture, data gaps were introduced by the DS resulting in approximately 8% data loss in the Level 0 product (i.e. 8 out of every 100 minutes of data was not included in the Level 0 product). These gaps were undetected at the processing station until report

4、ed by JPL and NASDA.Lesson(s) Learned: Loss of original implementation personnel and management.Recommendation(s): Ensure that necessary actions are taken to retain skills where appropriate or to ensure adequate knowledge transfer when personnel changes do occur. Evidence of Recurrence Control Effec
