Question about CALIPSO VFM data of February 2016

by benhurmp » Tue Jan 19, 2021 6:31 pm America/New_York

Hello,

I downloaded CALIPSO data (Vertical Feature Mask) from NASA ASDC for the time range 2006-2019, but realized that there is no data for February 2016. I did a brief search, but found nothing that could explain the missing data. Was there a problem with the satellite in that month? Thank you.

The anomaly was also reported on this tool, summarized below.

Acquisition Information: The CALIPSO satellite platform transitioned to Command and Control Reduced mode following a GPS anomaly on January 28, 2016 at 09:55:38 UTC. The payload was commanded to SAFE mode on January 28, 2016 at 16:14:11 UTC due to the platform transition to Command and Control Reduced mode. Science data was corrupted due to the GPS anomaly and resulting platform transition to Command and Control Reduced mode on January 28, 2016 from 09:55:36 UTC to 16:14:11 UTC. No science data is available from January 28, 2016 at 09:55:36 UTC until March 14, 2016 at 17:35:37 UTC.
