Regional IASI Retransmission Services

These comparisons are made with IASI level 1c data, on IASI’s native grid. The level 1c files are generated using AAPP from the incoming level 1c regional data, and are compared with the corresponding level 1c files generated from global level 1c data from Metop

Explanation of monitoring files:

  • Nav Mapping contains a plot of the regional navigated fields of view, superimposed upon the Global, providing a graphical display of the navigation error.  Data has been screened for invalid locations.
  • L-G Difference Maps contain plots of the differences between local and global raw (unscaled) radiance counts.  Data has been screen for invalid navigation and invalid counts observations.
