Metadata - Grande Ronde Water Temperature Model Climate Change Results

The simulation was produced using a HeatSource water temperature model, calibrated to late
summer (8/6-8/27) 2010 conditions.  For more information on the study, please see the technical report.
Data include summary statistics by study node and scenario.  For more detailed data, including
hourly values from the simulation, contact the author (David Graves) directly at grad@critfc.org.

The files included are:

12_09report.pdf: Technical Report describing the project and its results

Overview_Inputs_and_Results.doc: Overview of the input scenarios and the results

GR_CC_Model_StatResults.xls: Spreadsheet containing the statistical water temperature outputs at all study nodes
and scenarios in the simulation.

GR_CC_Model_H20TempStats.shp (and several associated files): GIS Layer containing the statistical water temperature
results at all study nodes and scenarios in the simulation.

The statistical results are reported at intervals of 100 meters upstream from the mouth of each river,
and contain the following parameters, as abbreviated in the field columns:

Scenario Family
A1B: The A1 scenario family assumes very high economic growth, global population peaking mid-century and then declining, and energy needs being met by a balance of fossil fuels and alternative technologies. A1B (a subset of the A1 family) lies near the high end of the spectrum for future greenhouse gas emissions, particularly through mid-century. A1B projects a future where technology is shared between developed and developing nations in order to reduce regional economic disparities.
B1: The B1 scenario family lies near the lower limit of projected changes in greenhouse gas emissions. The B1 scenario assumes global population growth peaks by mid-century and then declines, a rapid economic shift towards service and information economies, and the introduction of clean and resource-efficient technologies.
Both scenario families are considered equally probable.  Each scenario family includes the averaged results of 20 global climate models run with the given scenario, weighted by each model's ability to replicate 20th century climate in the Pacific Northwest.

Time Periods Modeled
2010: 2010 run with actual data collected by the Grande Ronde project (from stream loggers and FLIR flight).
2020s: Simulation from 2010-2039
2040s: Simulation from 2030-2059
2080s: Simulation from 2070-2099

Statistics (all statistics are reported in degrees celsius)

Avg = Mean Temperature
Max = Maximum Temperature
Min = Minimum Temperature
MeanDailyMax = Mean Daily Maximum Temperature
MeanDailyMin = Mean Daily Minimum Temperature

For example, the data value for column A1B2020sMeanDailyMax and record 21.9 on "Beaver" is the Mean
Daily Maximum temperature in the 8/6-8/27 period for the 2010-2039 simulation, at the study node that is 
at River km 21.9 on Beaver Creek.
