AERPARAM_MOD

File: READ_AERO.f

Summary: This module reads, time-interpolates, and stores fields needed by the radiation code in the prescribed-aerosol configuration of modelE. Subroutine updateAerosol2 provides the fields used to calculate the direct radiative effects of aerosols. Subroutine dCDNC_est provides a parameterized estimate of changes of lower-tropospheric CDNC relative to 1850, as input to prescriptions of aerosol indirect effects on cloud cover and optical depth. Dust aerosols are currently ingested via a separate module.

Subroutines:

dcdnc_est

finds change in cloud droplet number concentration since 1850

updateaerosol

updateaerosol2

updateAerosol2 reads aerosol file(s) and calculates A6JDAY(lma,6,:,:) (dry aerosol Tau) for current day, year. On startup, it allocates a6jday and plbaer, and reads plbaer. Note that jYearA may be negative, which is the Model E method for indicating that the data for abs(jYearA) is to be used for all years (this matters when time-interpolating between December and January).
