Worldview

• Redundant processing strings on 2 independent networks in different buildings will greatly reduce the possibility of data being unavailable due to system outages

• LANCE AMSR2 NRT data products will be available at AMSR SIPS on GHRC DAAC, for 7-14 days

L1R Input Data: Latency of Standard vs NRT Product

Standard L1R processing• pole to pole 1/2 orbits• data files complete• consistently not meeting 3 hour LANCE NRT processing

requirement

NRT L1R processing• one satellite downlink, roughly a whole orbit• we split the NRT L1R files at the southernmost observation,

creating approximate 1/2 orbit files for processing• occasional data loss• meet LANCE NRT 3 hour processing requirement
