List of netCDF files in the data repository and information about the contents:

seabed_initial_grainsize.nc
    This file contains initial seabed grain size distribution adapted from Moriarty 
    et al. (2021) and Nichols et al. (1991). The seabed grain size fractions are 
    contained in the variables sandfrac_01, sandfrac_02, sandfrac_03, and sandfrac_04, 
    representing sand, silt-rich flocs, clay-rich flocs, and unnaggregated mud. Two bed 
    layers are organized with layer 1 at the surface and layer 2 beneath. Latitude and 
    longitude coordinates of the approximate grid cell locations are contained in the 
    variables lat and lon. For more information, see Figure S1 in the associated 
    publication (supplementary material).
    
seabed_stresses.nc
	This file contains average bottom bed stress magnitudes for the year 2001 
	(2001-01-01 to 2001-12-31) including current-induced and wave-induced stresses.
	Averages were computed by calculating the bed stress magnitude at 3-hr intervals from
	u- and v-components, then averaging magnitudes over time. Latitude and 
    longitude coordinates of the approximate grid cell locations are contained in the 
    variables lat and lon. For more information, see Figure S2 in the associated 
    publication (supplementary material).
    
particle_parameters_ballasting_effect.nc
	This file contains the characteristics of the organic and inorganic particles used
	in the modeling study, including organic particles (phytoplankton, small detritus, 
	and large detritus) and inorganic mineral particles (sand, silt-rich flocs, clay-rich 
	flocs, and unaggregated clay). This includes the minimum and maximum settling 
	velocities as formulated by the ballasting effect for enhanced sinking at high TSS 
	concentrations. For more information see Table 1 and Section 2.2.3 "Ballasting
	effect for particle sinking rates" in the associated publication, and Figure S3 
	(supplementary material).
	
cbp_data_for_kd_zsd_equations.nc
    This file contains data from the Chesapeake Bay Program datahub, organized to 
    include only surface water data from specific times when (1) TSS, Salnity, and Kd 
    were sampled concurrently and when (2) VSS, Kd, and ZSD were sampled concurrently.
    Stations correspond to the following 33 station names, in order (1 to 33):
    CB1.1, CB2.1, CB2.2, CB3.1, CB3.2, CB3.3C, CB4.1C, CB4.2C, CB4.3C, CB4.4,
    CB5.1, CB5.1W, CB5.2, CB5.3, CB5.4, CB5.4W, CB5.5, CB6.1, CB6.2, CB6.3, CB6.4,
    CB 7.1, CB7.1N, CB7.1S, CB7.2, CB7.3, CB7.3E, CB7.4N, EE3.5, CB7.4, CB8.1, CB8.1E.
    Data from 1998-2019 were used to fit equations using multiple linear regression
    analysis, and Kd and ZSD data from 1984-2019 were plotted to show the usefulness
    of the equations. For more information, see Figure S4 in the associated publication
    (supplementary material).
	
cbp_data_for_skill_assessment.nc
    This file contains data from the Chesapeake Bay Program datahub, organized to
    include only surface water data from the years 2000 to 2005 for variables
    salinity, temperature, Kd, ZSD, FSS, VSS, and TSS. Stations correspond to the 
    following 33 station names, in order (1 to 33):
    CB1.1, CB2.1, CB2.2, CB3.1, CB3.2, CB3.3C, CB4.1C, CB4.2C, CB4.3C, CB4.4,
    CB5.1, CB5.1W, CB5.2, CB5.3, CB5.4, CB5.4W, CB5.5, CB6.1, CB6.2, CB6.3, CB6.4,
    CB 7.1, CB7.1N, CB7.1S, CB7.2, CB7.3, CB7.3E, CB7.4N, EE3.5, CB7.4, CB8.1, CB8.1E.

    as well as Figure S5 (supplementary material).
