Load scenarios for Ecosupport
BNI Technical Report Series No. 4, ISBN: 978-91-86655-03-7
In the project ECOSUPPORT, three coupled physical-biogeochemical models (ERGOM,
RCO-SCOBI and BALTSEM) are used to produce an ensemble of combined
climate change - nutrient load scenarios. The atmospheric driving forces for the
models are produced by two global climate models, ECHAM5 and HadCM3; and
these results are dynamically downscaled using the RCAO model at the SMHI,
see Meier et al. (2011) and references therein. Since, results from dynamic hydrological
models were not available, river runoff were constructed from the net
P-E balance of the RCAO model results. Nutrient load scenarios was to be explicitly
given, but effects from climate change induced river runoff variations were
estimated.
In total, four different climate change scenarios produced and four
different assumptions on direct anthropogenic changes in nutrient loads, thus in
total 16 combinations. The nutrient load scenarios comprised of; one reference
with approximately unchanged loads, one pessimistic business as usual and two
more optimistic, current legislation and Baltic Sea Action Plan. All the latter
based on previous work. This report describes the construction of these nutrient
load scenarios.
