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.

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.

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.
        ENDIF

     ENDDO
     IF ( .not. FOUND ) THEN

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