What's new in this version

Updates to forward model

Bug fixes in forward model

Trap for negative CRUTES in rpmares_mod.f (adj33_001)

Despite the setting of negative roots to zero, sometimes the code still ends up with negative CRUTES. Trap for it here to prevent mysterious crashing later.

Updated lightning parameterization and fix for cloud-top-height algorithm (v9-01-01)

Updates to a6_read_mod.f and lightning_nox_mod.f. Details in Lee's description:

Updates to adjoint model

Bug fixes in adjoint model

Mover error checking for O3 assimilation (adj33_002)

'Nicolas Bousserez wrote:

the code crashes in "input_adj_mod.f" when doing the checking of observation settings (see line 2027 in my code). It is apparently due to "IDCSPEC_ADJ", which is not allocated/defined yet at the time the program executes those lines. I'm skipping these checks for now then. Note: The code crashes also when using "TES_O3_OBS" instead of "SCIA_DAL_NO2_OBS", so it is not related to what I implemented apparently.

For the TES_O3_OBS simulation, the O3 species must be defined as an observed species as part of the cost function in input.gcadj to that ozone adjoint sensitivities can be accrued in the TES ozone observation operator. To ensure that this happens, the following block of code has been moved from input_adj_mod.f to subroutine INIT_CSPEC_ADJ in adj_arrays_mod.f, as it can only be called after the CSPEC variables have been initialized.

#elif defined ( TES_O3_OBS ) 
     ! Since the O3 obs operators will pass adjoints back 
     ! to CSPEC via CSPEC_AFTER_CHEM_ADJ, we need to make sure that 
     ! these species are listed as observed species
     FOUND = .FALSE.
     DO N = 1, NOBS_CSPEC

        IF ( TRIM( NAMEGAS( IDCSPEC_ADJ(N) ) ) == 'O3' ) THEN
           FOUND = .TRUE.

     IF ( .not. FOUND ) THEN

        CALL ERROR_STOP( ' Need to list O3 as observed species',
    &                    ' input_adj_mod ' )
