Activities of the NWP SAF


Introduction

The SAF is concerned with the NWP data assimilation process rather than with generating geophysical parameters. Its main deliverables are software packages for implementation at NWP centres within their data assimilation schemes, or at EUMETSAT central processing facilities or at other SAFs.

Instrumentation

The work of the SAF is organized according to instrument type rather than geophysical parameter. The current areas of work in the NWP SAF, and the main deliverables defined for each, are:

  • ATOVS (including AAPP)
    • Improved and extended versions of AAPP updated for distribution periodically
    • Integrated monitoring and tuning reports

    More about AAPP

  • IASI (and other advanced sounders)
    • Specification of NWP interface options for European users
    • 'Day-1' processing system for IASI+AMSU+AVHRR through extension of AAPP

    More about IASI

  • MVIRI/SEVIRI (and other geostationary imagery)
    • Integrated monitoring report on satellite winds in NWP
    • New/improved observation operators for satellite winds
    • Geostationary radiance assimilation

    More about atmospheric motion vectors

  • Scatterometers
    • New/improved observation operators, pre-processing and retrieval schemes, and quality control, for SCAT, ASCAT and SeaWinds
    • Integrated monitoring report on scatterometer data in NWP

    More about scatterometers

  • SSM/I and SSMIS
    • 1DVAR retrieval scheme prepared for distribution then improved/extended

    More about SSM/I and SSMIS

  • Ozone monitoring instruments
    • Monitoring of ozone retrievals

    More about ozone monitoring instruments

  • Radiative transfer model development (including RTTOV)
    • Improved and extended RTMs updated for distribution annually
    • Fast RTM for IASI and AIRS
