Operational dates: November 28, 2006 - present

Morning orbit: 2130 LST ascending node, 0930 LST descending node

AVHRR instrument: 6 channels (AVHRR/3)

Spacecraft ID (PACS):

Abnormalities:

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.

Table D.5-1 contains the PRT weighting factors for MetOp-A and Table D.5-2 contains the radiance of space and the coefficients for nonlinear radiance correction quadratic for MetOp-A.

Table D.5-3 contains MetOp-A coefficients d0, d1, d2, d3 and d4 that relate temperature, TPRT (Kelvin) of each PRT to count value, CPRT, 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

Table D.5-17 contains the measured channel characteristics for MetOp-A AMSU-A (channels 1-15). The central frequencies are interpolated from the temperature dependent data to 15 C. The f1, f2, f3, and f4 for channels 11-14 are computed from tabulated values. All values are for 15 C. Detailed information on the terminology used in this table can be found in Section 3.3.2.1.
