• 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)
