Description: This directory contains model simulation data from RCO-SCOBI as described in the publication
"Sources of uncertainty in future projections for the Baltic Sea" and its supplementary material.

----------------------------------------------------------------------------------------------------------------

The sub-directories contain three types of ascii files including headers:

include files *.I, time series data *.asc and maps *.asc.

----------------------------------------------------------------------------------------------------------------
1) Include files: monthly river data of 30 rivers (for the location and river names see Meier et al., 1999)
starting in January 1971. These data are displayed in Fig.3a. The header is

2) In Figs. 3 and 4 the other time series are displayed.

Temporal resolution:
1. Nutrient loads, primary production and nitrogen fixation: monthly
2. Hypoxic area: annual
3. Volume averagde temperature and salinity: 2-daily data with start on 1975-03-09 (historical period)
or on 2005-10-29 (future period, Model A, B, D)
or on 2006-01-01 (future period, Model C)

-------------------------------

Formats:

Ad 1. nutrient loads, primary production and nitrogen fixation:

idum,iyear,imonth,dum1,dum2,dum3,dum4,dum5,dum6,dum7,dum8,dum9,dum10,dum11,dum12,dum13,dum14,dum15,dum16,dum17,dum18,dum19,dum20,dum21,dum22,dum23,dum24,dum25,dum26,dum27

idum  =1
iyear =year
imonth=month

dum3 = primary production
dum4 = nitrogen fixation

dum17= atmospheric deposition P
dum18= atmospheric deposition N

dum19= riverborne nutrient loads P
dum20= riverborne nutrient loads N

dum21= point sources P
dum22= point sources N

Ad 2. hypoxic area

year, hypoxic area, anoxic area

(note anoxic area is not displayed in Fig.4 but part of the data)

3) The maps displayed in Figs 5-7 of the main text and in Figs S1-S4 of the supplementary material have the following header

1. Number of snapshots
2. x dimension IMT=320
3. y dimension JMT=362
4. Minimum
5. Maximum
6. Mean 
7-10. Coordinates of the lower left and upper right corners of the grid

For instance:

           1
         320
         362
  8.4691696E-02
   7.299415
  0.5977728
   9.016700
   30.35003
   53.84163
   65.90829

The following column contains data on the RCO-SCOBI grid with a horizontal resolution of 2 nautical miles.
Land points are identified by the dummy value  1.0000000E+10.
