D.1 NOAA-15 (K)

Launch date: May 13, 1998

Operational dates: December 15, 1998 to present

Morning orbit: 1930 LST ascending node, 0730 LST descending node

AVHRR instrument: 6 channels (AVHRR/3)

Spacecraft ID: 4

Abnormalities: During NOAA-15 activation and evaluation, it was determined that AMSU-A channels 7 and 15 were switched. This switch should be transparent to Level 1b users as the channels were corrected (switched back) by the ingest software, however, direct readout users should be aware of this problem. Only the radiometric data was affected, the housekeeping temperatures, antenna patterns, beam efficiency and beam widths of channels 15 and 7 oscillators are correct as they are now and were not affected by the switch. Band pass for channels 7 and 15 was also not affected due to extremely broad rf-detectors.

The NOAA-15 AMSU-B instrument is experiencing RFI contamination whose effect is dependent upon channel, geographic location, and current spacecraft antenna configuration. Calculations for generation of corrections for this contamination is an on- going effort. For the latest corrections needed for processing of this data see Appendix M.

On 10 July 2000, there was an apparent failure of the NOAA-15 AVHRR scan motor. HRPT and APT image data was missing through July 12, orbit 11250. On this orbit, AVHRR synchronization was restarted and HRPT and APT image data temporarily resumed. AVHRR synchronization was again lost 22 July on orbit 11395. Tests during December 2000 and January 2001 have shown that lowering the temperature of the instrument has restored a degree of stability. Beginning 20 March 2001, NOAA began to resynchronize the AVHRR once daily at 0730 UTC. The AVHRR has shown the ability to retain synchronization for longer periods with this daily reset. During the time of the resynchronization, there is a very brief disruption on all data in the HRPT transmission. When the AVHRR is in synchronization, usable images may be obtained. When the AVHRR synchronization is out of limits, images are unusable. HRPT transmitter will remain ON; the APT transmitter turned ON at 1611 UTC, 15 March 2001. At 1820 UTC, on 30 October 2000, the NOAA-15 AMSU-A Channel 14 failed and is no longer usable.

Up to date information regarding abnormalities on the POES spacecraft and instruments can be found at: http://www.oso.noaa.gov/poesstatus/. This website allows a user to search and sort on any POES spacecraft, subsystem or instrument status. Once a user narrows down their window of interest, further details can be obtained by going to the NOAA/NESDIS/Office of Satellite Operations' (OSO) archive of weekly status reports at: http://noaasis.noaa.gov/NOAASIS/ml/podocs.html.

The slope and intercept for the NOAA-15 HIRS/3 visible channel (Channel 20) are given in Table D.1-3.

**Table D.1-3. NOAA-15 HIRS/3 Channel 20 slope and intercept (albedo %).**
Source	Slope	Intercept
Pre-launch calibration	0.02336	36.0500
Post-launch calibration (May 2002)	0.03174	47.1100
Notes: 1. To retrieve the albedo, use the following equation: albedo = (intercept + slope x C) / cos(z), where C=earth view count, z=solar zenith angle. Both C and z vary from pixel to pixel. 2. Post-launch calibration is traceable to the Libyan desert calibration site, for which the HIRS channel 20 albedo is ~36.1%. Further update to these coefficients may be needed as the instrument degrades over time.

Table D.1-4 contains the NOAA-15 HIRS/3 central wave numbers and band correction coefficients for the thermal channels.

Note: The albedo ranges given in parentheses are nominal; the points of intersection of the two regression lines are located at 496, 511, and 491 counts (rounded off to the nearest integer) for channels 1,2, and 3A respectively. This information is based on the data in Instruction Manual and Alignment/Calibration Handbook and Optical Data, submitted to NASA/GSFC by ITT Aerospace/Communications (Report 8172836, Rev A), October 1997.

Table D.1-7 contains NOAA-15 AVHRR/3 visible channel information such as equivalent width, ω, effective central wavelength, λ_e, and in-band solar irradiance, F.

Note: These quantities are based on the solar irradiance data of Neckel and Labs, 1984, which is a widely used source of such data.

Table D.1-8 contains NOAA-15 coefficients d₀, d₁, d₂, d₃ and d₄ that relate temperature, T_PRT, (Kelvin), of each PRT to count value, C_PRT, by the equation:

$T sub {PRT} = d sub 0 + d sub 1 times C sub {PRT} + d sub 2 times C sub {PRT}^2 + d sub 3 times C sub (PRT)^3 + d sub 4 times C sub (PRT)^4$
