Thanks to Karen for presenting this ppt.
With POES, we met some problems between global and local level 1B :

presents global/local differences for POES calibration and navigation
http://guy.rochard.free.fr/meteo/fichiers/10282.doc
indicates the needed coherence between local & global calibrations.
With NPP & NPOESS, we could met similar troubles.
The following slide indicates other problems to solve for both global
and local preprocessings to optimize the coupling of instruments.

* http://www.meteorologie.eu.org/ici/
shows the benefit to collocate AVHRR and HIRS.
* Why not a collocation of VIRSS, CrIS, ATMS, CMIS ?…
http://guy.rochard.free.fr/meteo/fichiers/localglobalHIRS.doc
shows that a too large difference between NESDIS (global)
and Lannion (local) rejects one of the data source in NWP.
* About navigation of the data, collocation + landmarks are
the best using automatic software.
* About calibration, a compromise must be found between the
global preprocessing (using one full orbit) and direct readout.

SafetyNet is a system of 15 globally distributed SMD receptors linked to the centrals via commercial fiber, it enables low data latency and high data availability

Direct readout :
The hardware exists…so, now, the software has to come.!…
NPP & NPOESS also…

* Outside USA, it’s not sure to get SAFETY NET data in 20 mn. * It’s necessary for regional use to get the data through direct readout access up to 1B navigated radiances (at least), then : * A local preprocessing package is necessary as AAPP for POES. * Coherence between “local/global” calibration & navigation is needed as collocation between visible, infra-red and microwave… and an operational monitoring of this coherence should exist * Up to level 1B, we must rely on the manufacturers of the radiometers and spacecrafts.. Above 1B, all should should get benefit from a cooperation with users en scientists.
