2.10.1 Latency

Latency is mainly a factor for the products generated systematically (i.e. the medium resolution products and the wave mode products).

Two categories of product distribution services are provided by the PDS:

• Near real time (NRT) services
  

  NRT services are typically three hours from sensing for data used in forecasting or tactical operations (global and regional products produced and distributed systematically). For applications requiring high resolution images (agriculture, forestry, soil moisture, etc.) NRT products are typically available one to three days from sensing.

• Off-line service
  

• Off-line service (OFL) is typically available from a few days to weeks from data take. Off-line products benefit from superior data on calibration, auxiliary data, and precise orbit data.
