Base vs. Alternative Scenarios, Difference Maps

Each link-suite of comparisons of the Future Base vs. Future Alternative scenario(s) has a single pdf file containing multiple graphical difference-mapsets (1 mapset per Alternative's Variable & its temporal attribute).

Each variable's difference-mapset shows the color-scaled raster results, and vector contours of the area of marsh that exceeds selected ecologically-meaningful thresholds for the variable, and vector contours of the marsh area of the ecologically-meaningful (+/-) differences between the Base and Alternative for the variable. Simple tables in each map graphic show those area calculations. Summary comparisons of these marsh areas across multiple Alternative scenarios are provided in tablular and bar graph formats.

Not using standard figure captions, the below difference map figures have the following labeling-characteristics:
See the previous Scenarios simulated table for label/definitions of the Scenarios, and the previous Performance Measures table for label/definitions of the Performance Measures (and Variables).

With derivation methods explained in the Task 4 Model Application report (2026) text, the below (Report Table 3) defines the dates of the 30-d mean output files, for the High vs. Low flow years, wet vs. dry seasons.

________

Map header-label syntax is in either 2 or 3 dot (".") separarated parts, depending on whether it is a Period Of Simulation (POS) statistic:

2-part) ScenarioName.VariableNameOutputDate denotes the Scenario, and the Variable's daily mean over a 30-day bin ending on the OutputDate, or simply the Variable's calculated rate of change between the 52-year simulation's beginning and end (for rates of P accumulation and peat accretion).

3-part) ScenarioName.VariableName.POSmean denotes the Scenario, and the Variable's mean over the 52-yearr Period Of Simulation.

NEberm subregion difference map results (selected variables, selected temporal)

*** These subregion map results are simply a spatial-zoom of the (later section's) Basin-wide region results. The primary purpose of creating this NEberm subregion zoom of spatial map Performance Measures is to
quantify the marsh area difference map results that include only this Northeast subregion,
where the most significant hydro-ecological responses to Alternative scenarios are expected (and indeed occurred). The marsh area of this NEberm subregion is ~30% that of the Basin-wide region.
