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
In future the following MODIS page will be automatically updated:

2/252015 Aqua and Aura DOY 047 Missing Data Status
The Norway ground station is reporting that the DOY 047 Aqua and Aura data which they had intended to replay to EDOS is corrupted. EDOS is in the process of trying to recover the corrupted data to perform our own analysis and see if any portion of the data can be recovered.

2/20/2015 Norway Data Recovery Update for EDOS Customers
EDOS is still waiting to recover the data from Norway. The station has assured us that they are holding the data and will eventually be able to replay it. Right now they have an issue that requires an engineer and the current weather conditions have prevented an engineer from reaching the site. EDOS will reprocess as soon as the contacts are recovered.

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.
