• On April 28, a new Preprocessor and 1b format was implemented – Code Modified to Incorporate
• New MHS Code
• Field of View (FOV) size change for HIRS
• HIRS calibration and format changed
• AMSU-A calibration and format changed
• AVHRR format changed
• Other 1b/1b* format changes
NOAA-N Changes
• MHS/MIU Issues– MHS and AMSU-B Differences
• Channels Frequency are Similar– Channels with different frequency
» H2 and 17
» H5 and 20
• Number of warm target PRTs– MHS has 5
– AMSU-B has 7
• Different Algorithms for Calibration
• 1b/1b* format similar
NOAA-N Changes
• MHS/MIU Issues– Understanding different modes
• Nominal modes
• Non-nominal modes
• MIU nominal modes
• MIU non-nominal modes
– Accommodating different modes• Set flag for Nominal and Non-
Nominal modes– Operational nominal modes 99% of
time
NOAA-N Changes
• HIRS Issues– Field of View Size Change for HIRS
• HIRS/4 10KM FOV compared to HIRS/3 20KM FOV
– Users may need to change software, especially where co-location with other sensors such as AVHRR
– Patch Temperature changed from 100 to 95K
– Added a 5th Internal Warm Target temperature sensor and third telescope temperature sensor
– Added extra bit to the electronic serial number in the Digital A data stream Element 63 Bits 40-44
• Software change
• Bits redefined in 1b
NOAA-N Changes
• HIRS Issues (Cont.)– Software Correction for the Operational HIRS
Lunar Intrusion detection
– HIRS Calibration Algorithm Version 4.0
• New algorithm introduced to replacement old operational HIRS calibration algorithm
NOAA-N Changes
• AMSU-A Issues– Correction of Lunar contamination
• Required minor change to 1b format– Header and Data record
• Plan to move detection to Earth location Software
– Correction for sudden jumps in the calibration counts (NOAA-17 Channel 3 anomaly)
• Required minor change to 1b format– Header and Data record
NOAA-N Changes
• AVHRR Issues– Change to AVHRR Scaling Factors for
some of the AVHRR nonlinear radiance coefficients
– IR Operational/Test Cal Channel 4 coefficient 3
– IR Operational/Test Cal channel 5 Coefficient 3
NOAA-N Changes
• New Telemetry File– File contains telemetry that is not
contained in instrument 1b• Will be useful for MIU data when in Non-
nominal modes
• All telemetry data will now be archived
– File uses AIP 1a file format
NOAA-N Changes
• Incorporation of CLAVR-X flags to AVHRR 1bs– Prototype and timing tests complete
Additional Preprocessor Enhancement
• On April 28, Moved Preprocessing System from Amdahl Enterprise Server to IBM p655 (AIX Distributed Scalable Power processor(SP))– Improved Processing Speed
– Reduced Processing Cost
New Data Processing Platform
• Reason for change– Current Front End Processor (FEP) is out dated
– Need to Allow Ingest of Metop CCSDS data (Phase 2)
• Acceptance testing with user community was suspended due to interface problems encountered with Satellite Operations Control Center(SOCC) systems
• Internal testing and system modifications are underway• Will resume testing with user community once
modifications and internal testing are completed • Plan to transition to AFEP soon after
Advanced Front End Processor (AFEP)
Implementation (Phase 1)
• IPD will move to new NOAA Satellite Operations Facility (NSOF) – Scheduled to begin moving equipment August time
frame
– Scheduled to begin moving staff October time frame
– Plan to complete transition by January
– No interruption to service planned
Move to New Facility
• Blind Orbit Support for KLM series– OSD is investigating avenues for obtaining blind
orbits for KLM series of satellites

IJPS, IPSOverview of Upgrades for Metop
• New Ingestor and Advanced Front End Processor (AFEP) needs to be upgraded to allow
– Ingest of common instrument data, from the GDS as CCSDS VCDUs, in pipeline mode
– Frame synchronizing and filtering of GDS data at Ingest
– Receipt and distribution of ASCAT, GOME and GRAS Level 1b and IASI Level 1c products
– Ingest of blind orbit GAC, in pipeline mode
IJPS, IPSOverview of Upgrades for Metop(Cont.)
• Preprocessor needs to upgraded to
– Process blind orbit GAC in pipeline mode
– Produce common instrument Level 1b’s from Metop in pipeline mode
– Produce new Full Resolution GAC (FRAC)
