I have a question about DCOMPUTETD.
- Code: Select all
SUBROUTINE DCOMPUTETD(TD,PRESSURE,QV_IN,NX)
IMPLICIT NONE
INTEGER NX
DOUBLE PRECISION PRESSURE(NX)
DOUBLE PRECISION QV_IN(NX)
DOUBLE PRECISION TD(NX)
C NCLEND
DOUBLE PRECISION QV,TDC
INTEGER I
DO I = 1,NX
QV = DMAX1(QV_IN(I),0.D0)
c vapor pressure
TDC = QV*PRESSURE(I)/ (.622D0+QV)
c avoid problems near zero
TDC = DMAX1(TDC,0.001D0)
TD(I) = (243.5D0*LOG(TDC)-440.8D0)/ (19.48D0-LOG(TDC))
END DO
RETURN
END
What are the QV_IN and PRESSURE units? kg/kg and Pa?
