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, T_PRT (Kelvin) of each PRT to count value, C_PRT, by the equation:

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