8. Translating Big Data into Big Climate Ideas By Brian R. Pickard (U.S. EPA, Landscape Ecology Division), Jeremy Baynes (Contributor), Megan Mehaffey (Contributor), Anne C. Neale (Contributor), Solutions Vol. 6, Issue 1, April 2015. In Brief: Climate change has emerged as the significant environmental challenge of the 21st century. Therefore, understanding our changing world has forced researchers from many different fields of science to join together to tackle complicated research questions. The climate change research community now faces the daunting task of disseminating massive amounts of information about possible future climates under differing scenarios to a broad audience. They also need to make the data readily accessible so that it can be used by scientists in other research fields. One potential solution for distribution and communication of the climate scenario information may be through the EnviroAtlas, a new geospatial application developed by the United States Environmental Protection Agency and its partners. This interactive mapping tool allows users to access and explore climate change modeling information in easily understandable formats while providing a range of information on different ecosystem goods and services, or the benefits people receive from nature. By incorporating future scenarios such as land use and climate change within EnviroAtlas, we can evaluate specific components of complex ecosystems within the context of forecasted futures. Linking climate change impacts to ecosystem services, such as clean air and water, allows for opportunities to demonstrate how climate change will impact ecosystems, societies, and human health. 8 http://www.thesolutionsjournal.org/node/237304

9. Joan Aron Comments and Suggestions 1 I just sent EnviroAtlas a question about finding the climate data discussed in that Solutions article. I could not find climate data. According to the Solutions article, NASA provided climate data to use EnviroAtlas as a platform for disseminating climate data for ecological applications. I'm trying to build on that platform to leverage the NASA and EPA investment for water quality decision-making related to ecosystem function. It would also be nice to connect to other applications like your Precision Farming work. If we can link your agricultural info to EnviroAtlas, that could be interesting since agricultural runoff contributes a lot of pollution and is a focus for pollution control. The characterization of agriculture is also important since USDA covers crops, forests, ranching and CAFOs. 9

10. Response from Anne Neale, EnviroAtlas Project Lead, US EPA, RTP, NC Many apologies that you were not able to find the data we described. We are sorry and embarrassed that the data are not available as promised in the article. When we published the article, we felt sure that we would have the data available by the time the article was published. We ran into some unforeseen complications and although we have all the data and software available on our development server, we have not been able to push that to our public facing site yet. We anticipate that the issue will be resolved soon and we can let you know as soon as the data are accessible. On July 22, 2015, the EnviroAtlas team will be hosting an informational meeting in downtown Portland, OR to showcase newly available data.

12. Disclaimer 1 The data for this download Esri File GeoDataBase (FGDB) contains many data tables and feature classes. Varying numbers of attributes within each data table were used to map the layers in the EnviroAtlas Interactive Map. We encourage users to evaluate the associated metadata for the tables and feature classes through the EnviroAtlas Interactive Map, the XML files included in this zip file, or the EPA’s Environmental Dataset Gateway (EDG). EnviroAtlas is an interactive web-based decision support tool designed to provide information about ecosystems and the benefits people receive from those ecosystems. This application represents the first peer-reviewed public release. EnviroAtlas will continue to evolve over the coming years with periodic public releases. We welcome and request your feedback on all aspects of the website and tools. 12

13. Disclaimer 2 EnviroAtlas is designed for use by government, professional, academic, and community users, as well as members of the public.

All modeled geographic data are, by their nature, imperfect and the data provided in this Atlas should not be taken as absolute truth but as the best approximation of that truth based on best available data. For site-specific data, EnviroAtlas data will not replace "boots-on-the- ground measurements" or local knowledge.

18. Joan Aron Comments and Suggestions 2 I need to have more metadata to understand the net flux of pollutants leaving agricultural fields and the locations where the flux applies. There may be multiple sources of data in the same watershed. I am especially interested in three geographical areas for the examples: Around Coos (Oregon) HUC 17100304 - Tenmile Lakes should be nearby Around Lower Maumee (Ohio) HUC 04100009 - Maumee watershed produces flux of nutrients to Lake Erie at Toledo Around Tensas (Louisiana) HUC 08050003 - near Mississippi River 18

22. Data Download Nitrogen and phosphorus datasets, except for water quality monitoring data, are downloaded from the Viewer Download Page. Water quality monitoring data for N/P are downloaded by HUC8 using the map as described below. These monitoring data were sampled for lakes, streams, estuaries, spring, reservoir and impoundment from 1995 to present. First, select one or more hydrologic units (HUC8s) by picking an action, then click on a HUC8 on the map to Add or Remove it from the list of selected HUC8s. Now, click on one of the buttons below to download the water quality monitoring attribute or geospatial data for the selected HUC8(s). Note that clicking on the Excel or CSV button offers two separate files containing Station and Result attributes.

24. 24 http://www.epa.state.oh.us/dsw/tmdl/index.aspx A TMDL is a written, quantitative assessment of water quality problems in a waterbody and contributing sources of pollution. It specifies the amount a pollutant needs to be reduced to meet water quality standards (WQS), allocates pollutant load reductions, and provides the basis for taking actions needed to restore a waterbody.

25. 25 http://www.epa.state.oh.us/dsw/tmdl/MaumeeRiver.aspx#123086615-monitoring The Maumee River watershed is located in northwestern Ohio. It drains a total of 5,024 square miles in Ohio and flows through all or part of 18 counties. Major municipalities partially or fully in the watershed include Toledo, Defiance, Findlay, Lima, Van Wert, Napoleon and Perrysburg. The watershed is predominantly comprised of cultivated crops with some urban development, hay and pasture lands, and forest. The Maumee River is a major tributary to the western Lake Erie basin.
