ISU Climate Science InitiativeISU Climate Science Initiative
Meeting objectives:
* To assess the level of faculty interest in research relating to climate science at ISU
* To identify opportunities to build partnerships at ISU between climate science and programs in bioeconomy, plant sciences, cyberinfrastructure, and climate-sensitive areas of research in agriculture, water resources, natural systems, and engineering for establishing ISU as a regional/national leader in climate science and impacts of climate change.

North American Regional Climate Change Assessment Program (NARCCAP)
• An international project to evaluate regional climate change for North America.
• Uses nested regional climate models: fine-scale models that use results of coarse global models as input.– How does uncertainty propagate from global
models through regional models?
• Develop multiple realizations of regional climate change for use in climate change impact assessment (patterned on global model data for the IPCC Fourth Assessment Report).

Seasonal Forecasting (MRED project)
• Weather forecasting is short-term (few days to 2 weeks)
• Climate projection is for decades
• Seasonal forecasting has had less attention, despite practical needs:– agriculture, construction and repair, transportation,
etc.
![Page 12: ISU Climate Science Initiative](https://reader036.fdocuments.in/reader036/viewer/2022062301/5681457e550346895db2559e/html5/thumbnails/12.jpg)
Seasonal Forecasting (MRED project)
• MRED project is patterned after NARCCAP:– uses output from the National Centers for
Environmental Prediction (NCEP) global model as input to fine-scale regional models
– many of the same participants as NARCCAP
• ISU has done some exploratory work using a similar approach.
• Project has been proposed to NOAA.

Examples of Studying Impacts of Climate Change
Global climate models have demonstrated skill in simulation of future climates (1980s GCMs projected accelerated warming in the Arctic that now is being observed)
Regional model output is being used for studying• Impact on land-use and climate change on landscape change
(C. Kling, CARD)• Impact of climate change on streamflow in UMRB (C. Kling, P.
Gassman, M. Jha, CARD)• Impact of climate change on tile drainage flow (A. Kalieta, M. Helmers, A&BE)• Changes in wind speed (wind power) under climate change (S.
Pryor, Indiana U)• Pavement performance under climate change (C. Williams, CCEE)

Midwest Consortium for Climate Assessment (MiCCA)
MiCCA’s mission is to translate and enhance the latest NOAA climate forecast products to maximize economic gains for agricultural producers and their agribusiness service providers in the U.S. Midwest through use of advanced regional models, interactive web-based decision-making tools, and high-volume customized delivery and feedback through the existing integrated regional, state, and county level extension service network throughout the 9-state region (MN, IA, MO, WI, IL, MI, IN, OH, KY).

Iowa Environmental Mesonet• Goal: Build a centralized clearing house for environmental data in Iowa
– "Network of networks": Collect, process and archive data from pre-existing networks
– Build two-way partnerships with data providers and data users; foster interdisciplinary collaboration and research
• Daily data processing:– IEM ingests over 300,000 obs/day (~111 million in 1996)– 20 GB of compressed Level2 NEXRAD data is processed, 10,000+
Level3 NEXRAD radar attribute files are ingested into the spatial database
– Thousands of NWS issued text products are processed to extract data and information.
– 99% of processing done in real-time.

Total cost of large-scale carbon capture and storage: $76 - $450/tC
Example: Added cost to drive your car.$(0.076-0.450)/kg C x (12 kg C/44 kg CO2) x 10.4 kg CO2/gal x (1 gal/25 mi) x 12,000 mi/yr
= $103 - $613/yr ($0.22 - $1.28/gal)
What’s it going to cost us?
