NASA’s Land, Atmosphere Near real-time Capability for EOS (Earth Observing System) (LANCE) provides data and imagery from Terra, Aqua and Aura satellites in less than 3 hours from satellite observation, to meet the needs of the near real-time (NRT) applications community. LANCE is a distributed system that builds on the existing EOSDIS capabilities. 

Anomalies in LANCE metrics
MODIS Aqua near real time input data currently has these gaps:
  ESDT   |    GapStartTime     |     GapEndTime    
---------+---------------------+---------------------
MYD00S  | 2015-02-16 02:20:16 | 2015-02-16 02:20:45
MYD00S  | 2015-02-16 02:58:59 | 2015-02-16 09:29:30
MYD00S  | 2015-02-16 16:11:29 | 2015-02-16 14:34:09
MYDGBAD | 2015-02-16 02:52:31 | 2015-02-16 09:23:18
Recieved MYD00S granules between 2015-02-16 02:20 and 14:34z are up to
12 hours late.
EDOS reports: A power outage at the Norway ground station on DOY 047 (February 16th) has resulted in a delay in receiving and processing several Aqua, Aura and NPP contacts at EDOS. EDOS is working with the ground station to recover the missing contacts. Customers should expect to receive some near real-time products late and out of order as well as some partial and missing level zero products. EDOS will reprocess level zero products as required once all data has been recovered from Norway.

 

OMI - On January 28 through January 29 2015 (about 36 hours) the OMSO2, OMAERUV, and OMTO3 products were not produced due a software problem in the Row Anomaly Flagging software. On January 29 all the granules were processed and nominal processing continued.

 

User Working Group (UWG)

LANCE is managed by ESDIS but steered by a User Working Group (UWG) responsible for providing guidance and recommendations concerning a broad range of topics related to the LANCE system, capabilities, and services.
