Update 18 - March 2002

IDL Files

The file jkmoore_idl.tar was missing the file: oceanarea_x3p.dat
The file x3p_routines.pro was updated to include the "get_x3p_coords" routine.
The tar file jkmoore_idl.tar has been updated to reflect the above changes.


Update 02 - March 2002

Input Files

The file jkmoore_inputs.tar was missing the input file: woa98_sst_surf_m_x3p.dat
There were three NaN values in the two files: bio_slope_x3p_globalV5.dat and hmix_levpd_min25_x3p.dat. Both of these files were corrected and replaced in the tar file: jkmoore_inputs.tar
The tar file jkmoore_inputs.tar has been updated to reflect the above changes.

Updates to Mixed Layer Model Since Publication

Variable thetaNmax
There is evidence that the maximum chl/C (chl/N) ratio can be higher in diatoms than other phytoplankton groups (Geider et al., 1997). I suggest using a thetaNmax of 4.0 for the diatoms and 3.0 for the other phytoplankton groups. This improves global chlorophyll fields in terms of winter season gyre values (too high around borders of the gyres in Moore et al. 2002). In depth-resolved applications this also improves the behavior of diatom biomass at the deep chlorophyll max.

New lambda function - for all phytoplankton groups

replace:   lambda = lambda_no3 * max(frat_sp, 0.5) ! used in DSR papers
with:        lambda = lambda_no3 * (frat_sp * 0.5 + 0.5)

This is a smoother function more true to the data presented by Geider (1992).
