SOIREE Modeling - Var in
State variables time series (inside the patch)

SOIREE Modeling
Updated October 2000
Authors: E. Hannon, C. Lancelot, P.W. Boyd
Contact: Prof. C. Lancelot (ESA-ULB, CP221, Campus Plaine, Bd du Triomphe, B-1050 Brussels, Belgium, lancelot@ulb.ac.be)

Note: these model runs were performed with the SWAMCO model.

Model results are compiled in the file “SOIREEmodel.xls”
This file includes 7 sheets:
Var.out: state variables time series (outside the patch)
Var.in: state variables time series (inside the patch)
Act.out: activities (biogenic elements fluxes) time series (outside the patch)
Act.in: activities (biogenic elements fluxes) time series (inside the patch)
BudgetC: integrated carbon budget
pCO2: surface pCO2 time series
Forcing: hydro-meteorological forcings

Comments:
Sheet 1 (Var.out):
60 days (10/02/1999 to 10/04/1999) time series of the state variables values, averaged daily
and over the upper mixed layer (UML)
See state variables list in Table 1 below.
Diatoms and autotrophic nanoflagellates chlorophyll a (columns AH, AI) are estimated on the
basis of the functional and structural metabolites concentration (state variables DAF and NFF),
using a conversion factor of 0.5 mg chla / mmol C

Sheet 2 (Var.in):
see Sheet 1

Sheet 3 (Act.out):
activities time series (outside the patch)
60 days (10/02/1999 to 10/04/1999) time series of the activities (biogenic elements fluxes)
values, integrated over the upper mixed layer (UML) and daily averaged.
See activities list in Table 2 below.

Sheet 4 (Act.in):
see Sheet 3

Sheet 5 (BudgetC):
Carbon budget of the Upper Mixed Layer, calculated over 13 days (site occupation of SOIREE) and
60 days since the initial iron release (inside and outside the fertilized patch)

Sheet 6 (pCO2):
Time series of daily averaged surface water pCO2 (in situ temperature, 100% wet) (inside and
outside the fertilized patch)

Sheet 7 (Forcing):
Time series of daily averaged wind velocity (m s-1), sea surface temperature (°C), and
mixed layer depth (m).
