!-----------------------------------------------------------------------
      IMPLICIT NONE

! GLAT : geodetic latitude in radians of the mass points on the computational grid.

! CZEN : instantaneous cosine of the solar zenith angle.

! CUTOP : (REAL) model layer number that is highest in the atmosphere
!        in which convective cloud occurred since the previous call to the
!        radiation driver.

! CUBOT : (REAL) model layer number that is lowest in the atmosphere
!        in which convective cloud occurred since the previous call to the
!        radiation driver.

! ALB  : is no longer used in the operational radiation.  Prior to 24 July 2001
!        ALB was the climatological albedo that was modified within RADTN to
!        account for vegetation fraction and snow.
!
! ALB  : reintroduced as the dynamic albedo from LSM

! CUPPT: accumulated convective precipitation (meters) since the
!        last call to the radiation.

! TSK2D : skin temperature

! IHE and IHW are relative location indices needed to locate neighboring
!       points on the Eta's Arakawa E grid since arrays are indexed locally on
!       each MPI task rather than globally.  IHE refers to the adjacent grid
!       point (a V point) to the east of the mass point being considered.  IHW
!       is the adjacent grid point to the west of the given mass point.

! IRAD is a relic from older code that is no longer needed.

! ACFRCV : sum of the convective cloud fractions that were computed
!          during each call to the radiation between calls to the subroutines that
!          do the forecast output.

! NCFRCV : the total number of times in which the convective cloud
!          fraction was computed to be greater than zero in the radiation between
!          calls to the output routines.  In the post-processor, ACFRCV is divided
!          by NCFRCV to yield an average convective cloud fraction.

!          ACFRST and NCFRST are the analogs for stratiform cloud cover.

!          VEGFRC is the fraction of the gridbox with vegetation.

!          LVL holds the number of model layers that lie below the ground surface
!          at each point.  Clearly for sigma coordinates LVL is zero everywhere.

! CTHK  :  an assumed maximum thickness of stratiform clouds currently set
!          to 20000 Pascals.  I think this is relevant for computing "low",
!          "middle", and "high" cloud fractions which are post-processed but which
!          do not feed back into the integration.

! IDAT  : a 3-element integer array holding the month, day, and year,
!        respectively, of the date for the start time of the free forecast.

! ABCFF : holds coefficients for various absorption bands.  You can see
!         where they are set in GFDLRD.F.

! LTOP  : a 3-element integer array holding the model layer that is at or
!         immediately below the specified pressure levels for the tops 
!         of "high" (15000 Pa), "middle" (35000 Pa), and "low" (64200 Pa) 
!         stratiform clouds.  These are for the diagnostic cloud layers 
!         needed in the output but not in the integration.

! NRADS : integer number of fundamental timesteps (our smallest
!         timestep, i.e., the one for inertial gravity wave adjustment) 
!         between updates of the shortwave tendencies.  

! NRADL : integer number of fundamental timesteps between updates of
!         the longwave tendencies.  

! NTSD   : integer counter of the fundamental timesteps that have
!         elapsed since the start of the forecast.

! GLW : incoming longwave radiation at the surface
! GSW : NET (down minus up, or incoming minus outgoing) all-sky shortwave radiation at the surface
! RSWIN  : total (clear + cloudy sky) incoming (downward) solar radiation at the surface
! RSWINC : clear sky incoming (downward) solar radiation at the surface

! TENDS,TENDL : shortwave,longwave (respectively) temperature tendency

! CLDFRA : 3D cloud fraction

! RSWTOA, RLWTOA : outgoing shortwave, longwave (respectively) fluxes at top of atmosphere

! CZMEAN : time-average cosine of the zenith angle

! CFRACL,CFRACM,CFRACH : low, middle, & high (diagnosed) cloud fractions

! XTIME : time since simulation start (minutes)

!****  IMPORTANT NOTES concerning input cloud optical properties  ******
!***********************************************************************
!
!--- The simple optical depth parameterization from eq. (1) of Harshvardhan
!    et al. (1989, JAS, p. 1924; hereafter referred to as HRCD by authorship)
!    is used for convective cloud properties with some simple changes.
!
!--- The optical depth Tau is Tau=CTau*DELP, where values of CTau are
!    described below.
!      1) CTau=0.08*(Qc/Q0) for cloud water mixing ratio (Qc), where
!         Q0 is assumed to be the threshold mixing ratio for "thick anvils",
!         as noted in the 2nd paragraph after eq. (1) in Harshvardhan et al.
!         (1989).  A value of Q0=0.1 g/kg is assumed based on experience w/
!         cloud observations, and it is intended only to be a crude scaling
!         factor for "order of magnitude" effects.  The functional dependence
!         on mixing ratio is based on Stephens (1978, JAS, p. 2124, eq. 7).
!         Result: CTau=800.*Qc => note that the "800." factor is referred to
!         as an absorption coefficient
!      2) For an assumed value of Q0=1 g/kg for "thick anvils", then 
!         CTau=80.*Qc, or an absorption coefficient that is an order of 
!         magnitude less.
!      => ABSCOEF_W can vary from 100. to 1000. !!
!      3) From p. 3105 of Dudhia (1989), values of 
!         0.14 (m**2/g) * 1000 (g/kg) / 9.81 (m/s**2) = 14.27 /Pa
!         => 14.27 (/Pa) * 100 (Pa/mb) = 1427 /mb
!      4) From Dudhia's SW radiation, ABSCOEF_W ~ 1000.  after units conversion
!      5) Again from p. 3105 of Dudhia (1989), he notes that ice absorption 
!         coefficients are roughly half those of cloud water, it was decided
!         to keep this simple and assume half that of water.
!      => ABSCOEF_I=0.5*ABSCOEF_W
!
!--- For convection, the following is assumed:
!      1) A characteristic water/ice mixing ratio (Qconv)
!      2) A temperature threshold for water or ice (TRAD_ice)

!      IN THIS MODE,THERE IS NO REFERENCE TO LAYER PRESSURES PD

!      MEAN PRESSURE PLM(J) AND PRESSURE LAYER I IS GIVEN BY
!         TAULM(PLM(I),PLM(J)). IT IS COMPUTED BY THE INTEGRAL

!           FOR LAYER-MEAN TRANSMISSIVITIES,THE USER THUS INPUTS
!        A PRESSURE ARRAY (PD) DEFINING THE PRESSURE LAYERS AND AN
!        ARRAY (PLM) DEFINING THE LAYER-MEAN PRESSURES.THE CALCULATION
!        DOES NOT DEPEND ON THE P ARRAY USED FOR PURPOSE 1 (P IS NOT
!        INPUTTED).
!
!            THE FOLLOWING PARAGRAPHS DEPICT THE UTILIZATION OF THIS
!       CODE WHEN USED TO COMPUTE TRANSMISSIVITIES BETWEEN SPECIFIC
!       PRESSURES. LATER PARAGRAPHS DESCRIBE ADDITIONAL FEATURES NEEDED
!       FOR LAYER-MEAN TRANSMISSIVITIES.
!
!          FOR A GIVEN CO2 MIXING RATIO AND STANDARD TEMPERATURE
!      PROFILE,A TABLE OF TRANSMISSION FUNCTIONS FOR A FIXED GRID
!     OF ATMOSPHERIC PRESSURES HAS BEEN PRE-CALCULATED.
!      THE STANDARD TEMPERATURE PROFILE IS COMPUTED FROM THE US
!     STANDARD ATMOSPHERE (1977) TABLE.ADDITIONALLY, THE
!     SAME TRANSMISSION FUNCTIONS HAVE BEEN PRE-CALCULATED FOR A
!     TEMPERATURE PROFILE INCREASED AND DECREASED (AT ALL LEVELS)
!     BY 25 DEGREES.
!         THIS PROGRAM READS IN THE PRESPECIFIED TRANSMISSION FUNCTIONS
!     AND A USER-SUPPLIED PRESSURE GRID (P(I)) AND CALCULATES TRANS-
!     MISSION FUNCTIONS ,TAU(P(I),P(J)), FOR ALL P(I) S AND P(J) S.
!     A LOGARITHMIC INTERPOLATION SCHEME IS USED.
!         THIS METHOD IS REPEATED FOR THE THREE TEMPERATURE PROFILES
!     GIVEN ABOVE .THEREFORE OUTPUTS FROM THE PROGRAM ARE THREE TABLES
!     OF TRANSMISSION FUNCTIONS FOR THE USER-SUPPLIED PRESSURE GRID.
!     THE EXISTENCE OF THE THREE TABLES PERMITS SUBSEQUENT INTERPO-
!     LATION TO A USER-SUPPLIED TEMPERATURE PROFILE USING THE METHOD
!     DESCRIBED IN THE REFERENCE.SEE LIMITATIONS SECTION IF THE
!     USER DESIRES TO OBTAIN ONLY 1 TABLE OF TRANSMISSIVITIES.
!
!     MODIFICATIONS FOR LAYER-MEAN TRANSMISSIVITIES:
!          THE PRESSURES INPUTTED ARE THE LAYER-MEAN PRESSURES,PD,
!     AND THE LAYER-MEAN PRESSURES ,PLM. A SERIES OF TRANSMISSIVITIES
!     (TAU(P'',PLM(J)) ARE COMPUTED AND THE INTEGRAL GIVEN IN THE
!     DISCUSSION OF PURPOSE 2 IS COMPUTED.FOR PLM(I) NOT EQUAL TO
!     PLM(J) SIMPSON S RULE IS USED WITH 5 POINTS. IF PLM(I)=PLM(J)
!     (THE -NEARBY LAYER- CASE) A 49-POINT QUADRATURE IS USED FOR
!     GREATER ACCURACY.THE OUTPUT IS IN TAULM(PLM(I),PLM(J)).
!        NOTE:
!     TAULM IS NOT A SYMMETRICAL MATRIX. FOR THE ARRAY ELEMENT
!     TAULM(PLM(I),PLM(J)),THE INNER(FIRST,MOST RAPIDLY VARYING)
!     DIMENSION IS THE VARYING LAYER-MEAN PRESSURE,PLM(I);THE OUTER
!     (SECOND) DIMENSION IS THE FIXED LAYER-MEAN PRESSURE PLM(J).
!     THUS THE ELEMENT TAULM(2,3) IS THE TRANSMISSION FUNCTION BETWEEN
!     THE FIXED PRESSURE PLM(3)  AND THE PRESSURE LAYER HAVING AN AVERAG
!     PRESSURE OF PLM(2).
!         ALSO NOTE THAT NO QUADRATURE IS PERFORMED OVER THE LAYER
!     BETWEEN THE SMALLEST NONZERO PRESSURE AND ZERO PRESSURE;
!     TAULM IS TAULM(0,PLM(J)) IN THIS CASE,AND TAULM(0,0)=1.
