Subject:
ASI/MPL/M1 - Reprocessed and Corrected: New overlap correction
DataStreams:asimplpolfsM1.b1
Description:
DATA REPROCESSED and CORRECTED: 

Vendor recently provided an updated overlap correction file which needed to replace the 
current overlap correction file in use. Data were reprocessed to reflect this new file. 
This does not affect MPL data quality.


The data were archived in December 2016. Please retrieve the reprocessed data for 
use in your analysis.

You may find these data using the ARM Discovery tool at the following link:

ORIGINAL DQR CATEGORY: Transparent - Does not affect quality

REPROCESSED and CORRECTED DATA ARCHIVED:2016-12

REPROCESS IDENTIFICATION NUMBER: RID 1510

---------------------------------------------------
--- ORIGINAL DQR DESCRIPTION ---
---------------------------------------------------

Vendor has recently provided an overlap correction which needs to replace the overlap 
currently being included in the data files. This does not affect MPL data quality.
Measurements:asimplpolfsM1.b1:
  • overlap_correction
  • overlap_correction_heights

ASI/MPL/M1 - Instrument averaging time increased to 30 seconds
DataStreams:asimplpolfsM1.b1
Description:
To understand what was causing frequent spikes in the MPL energy levels, the averaging 
time was increased to 30s during this period. The averaging time was reverted back to the 
original 10s averaging time at the end of the DQR period.
