Dataset Information
LIS Data Processing Anomalies

This web page lists anomalous data receipt and processing conditions for the Lightning Imaging Sensor (LIS) discovered after reprocessing with version 4.1. Please consult the documentation for determination of anomalous orbits, and the science/orbit data itself for anomaly flags, or see LIS notes at http://branch.nsstc.nasa.gov/lis_hk/LIS_notes.html

There was a problem with TDS (TDRS satellite anomaly) in which we lost the event scheduled at 17:41-18:01z. The data loss is as follows for all of the science data
(VR 3 - VR 6): 16:06:27z - 17:42:27z.
All engineering data was recovered.
12/03/2005 - (05337) 45881   Due to a late acquisition with TDRS on 05-337, some LIS and PR data was lost.
2006
01/30/2006 - (06030) 46776   Orbit 46777 is missing data, LIS science data interruption likely caused by passage through the South Atlantic Anomaly.
04/05/2006 - (06095)   47794
47795
There was a problem at STGT with a piece of equipment that distributes the data to the various entities. The time of the missing data is 095/09:42:27z-11:14:27z
05/22/2006 - (06142)   48525

The data gap was a result of a Q-channel return link that dropped out at White Sands resulting in a chain failover. The affected times are:
2006-142T07:14:30.75330 - 2006-142T08:47:31.75334
09/14/2006 - (06257)   50320 The data gap was a result interferrence with the Hubble telescope. The affected times are:
2006-257 10:29:25 to 2006-257 11:53:00
11/28/2006 - (06332)   51482

Communications interference.
03/17/2007 - (07076) 53189

  Interruption likely caused by passage through the South Atlantic Anomaly.
07/10/2007 - (07191) 54976 54975
54977
The data gap was the result of a non-recoverable data loss.
