GitHub Issue NOAA-EMC#341
Browse files Browse the repository at this point in the history 
This update includes the following:
(1) Add the capability of assimilating precipitation-affected radiances from AMSU-A and ATMS
(2) Enable the all-sky radiance assimilation for GMI
(3) Add the switch to use brightness temperature (SDR) instead of antenna temperature (TDR) for AMSU-A, ATMS and MHS

! NAME:
! Apply_AntCorr
!
! PURPOSE:
! Subroutine to apply an antenna correction to microwave instrument
! antenna temperatures, Ta, to produce brightness temperatures, Tb.
!
! CALLING SEQUENCE:
! CALL Apply_AntCorr( AC , & ! Input
! iFOV, & ! Input
! T ) ! In/Output
!
! INPUT ARGUMENTS:
! AC: Structure containing the antenna correction coefficients
! for the sensor of interest.
! UNITS: N/A
! TYPE: TYPE(ACCoeff_type)
! DIMENSION: Scalar
! ATTRIBUTES: INTENT(IN)
!
! iFOV: The FOV index for a scanline of the sensor of interest.
! UNITS: N/A
! TYPE: INTEGER
! DIMENSION: Scalar
! ATTRIBUTES: INTENT(IN)
!
! T: On input, this argument contains the antenna
! temperatures for the sensor channels.
! UNITS: Kelvin
! TYPE: REAL(fp)
! DIMENSION: Rank-1 (n_Channels)
! ATTRIBUTES: INTENT(IN OUT)
!
! OUTPUT ARGUMENTS:
! T: On output, this argument contains the brightness
! temperatures for the sensor channels.
! If an error occurs, the return values are all -1.
! UNITS: Kelvin
! TYPE: REAL(fp)
! DIMENSION: Rank-1 (n_Channels)
! ATTRIBUTES: INTENT(IN OUT)
!
! SIDE EFFECTS:
! The temperature array argument, T, is modified.
!
! PROCEDURE:
! For every FOV and channel, the antenna temperature, Ta, is converted
! to brightness temperature, Tb, using,
!
! Tb = (Ta - As.Ts) / (Ae + Ap)
!
! where Ae == antenna efficiency for the Earth view
! Ap == antenna efficiency for satellite platform view
! As == antenna efficiency for cold space view
! Ts == cosmic background temperature.
!
! Note that the observed earth view brightness temperature is used as a
! proxy for the platform temperature for the (Ap.Tb) component since
! there is no measurement of the platform temperature in-flight.
