| Subject: | Reprocess:SGP BLC reprocessing status |
| DataStreams: | sgpblcC1.00, sgpblcC1.a1, sgpblcprofC1.a1
|
| Description: | The BLC data was the subject of a reprocessing
effort last summer in support of the ARSCL
effort. As a result three distinct windows of
data with varying levels of processing have been
created.
1) 940401-961031 - not reprocessed. This data
has a 110m offset in the reported cloud base
height (see P980831.1). No sgpblcprofC1.a1
data available. Reprocessing required.
2) 961101-990630 - reprocessed. The 110m offset
was corrected in this data and the blcprof
data were created. This data still contains
the defunct field 'operational_state' which
was determined to be useless and was removed
in later data. This data will be reprocessed
at a later date to remove the operational_state
field to create a continuity with the current
data.
3) 990701-present - reprocessed/processed without
'operational_state' field. Offset has been
corrected or no longer exists. The format of
this data is the target for the previous two
data windows. |
