  1. The ATOVS and AVHRR Processing Package- Current Capability and Future Evolution Keith Whyte (Met Office), Tiphaine Labrot (Météo-France) and Rainer Schraidt (EUMETSAT)

  2. EUMETSAT NWP SAF Activities • AAPP for ATOVS • radiance monitoring • IASI (preprocessing, 1DVar, ICI) • MVIRI (winds monitoring, use in NWP, radiances) • Scatterometer (monitoring,..) • Ozone (no activity yet) • RT models (RTTOV, diverse profiles,…)

  3. The ATOVS and AVHRR Processing Package • Capabilities of AAPP V3.0 • AAPP V3 updates - 3.1, 3.2, … • Generation of AAPP V4.0 • Future of AAPP

  4. AAPP • Processing of (A)TOVS and AVHRR data to level 1b, 1c, 1d • Decommutation, navigation, calibration, mapping to common instrument grid • Derived scientific data, eg surface type, cloud mask • Unix + Fortran77, portable - implemented on several platforms

  5. AAPP V3.0 • integration of V2.0 to V2.9 - calibration updates, bug fixes, NOAA-16 • MAIA V2.1 • full NOAA16 capability - correction for HIRS scanning anomaly • further bug fixes • other enhancements - Backus-Gilbert convolution - cirrus test - ICI interface

  6. MAIA cloud-mask example NOAA16 14 February 2002 1130-1502UTC

  7. NOAA16 HIRS scanning correction Best adjustment between HIRS channel 8 and AVHRR channel 4

  8. Current updates to AAPP V3 • V3.1 Bug fix • V3.2 HIRS calibration files via Météo-France

  9. Anticipated further updates to AAPP V3 • Documentation revision • Minor bugfixes • Calibration updates, including NOAA-M capability • AMSU-A + HSB from Aqua • Moon contamination check • Surface-type check

  10. European ATOVS Retransmission Service • AAPP run at individual receiving stations • Retransmission of level 1c data • Implementation in Autumn 2002

  11. Local and Global AMSU data Locally-received data NOAA16 12 Feb 2002 0156 - 0530 UTC NESDIS global data

  12. Global - Local mapping comparison

  13. AAPP V4.0 • Consolidation of V3.x update releases • Fortran90 compatibility • MAIA V2.2 • Improved land/sea mask • Planck coefficients update for compatibility with NESDIS • Release February 2003 ?

  14. Further development of AAPP • Continued support through the NWP SAF • Upgrades • Calibration updates • New satellite updates • 18-month cycle for new full versions
