Partnering with the Pyramid Lake Paiute Tribe to Develop Tools for Emissions Modeling

Thinking about deserts usually conjures up images of sand and wind—not water. However, in the high desert region in western Nevada, you will find Pyramid Lake. One of the largest natural lakes in the state, this body of water exists entirely within the boundaries of the Pyramid Lake Paiute Tribe’s reservation, which is about 35 miles northeast of Reno.

Helping sawmills maintain compliance

Sawmills in the Western United States have an intriguing history. As mostly European-descendant settlements of the 19th century American West forged deeper into resource extraction of wood to build homes and towns, sawmills were developed to process immense logs into usable lumber. Naturally, a power source was needed to propel the industry beyond the work of hand-sawyers. Technology used to power the mills included water turbines and steam engines, while boilers provided steam for a sawmill’s kilns.

AEREarth: Visualize AERMOD Files in Google Earth

Air Sciences’ staff recently developed a tool called AEREarth for users who would like to visualize AERMOD air dispersion model input data in Google Earth before running the actual model. The AEREarth tool takes AERMOD input data files (extension .inp, or .api if using Lakes) and translates them into Google Earth KML files. These files allow the user to see a three-dimensional (3D) rendering of all air pollutant emissions sources characterized in the input file. The tool also can accept AERMOD BPIP files (.ppp, .pip, or .bpi) into 3D buildings. This visualization tool allows users to evaluate whether a facility is correctly configured in AERMOD, and provides a useful QA/QC check of the model data prior to conducting a potentially time-consuming model run.

  • Science in Support of Smart Regulation: How Air Sciences Helped Shape EPA’s Gold Mining Policy
    In the late 2000s, questions emerged about whether hydrogen cyanide (HCN) emissions from gold mining cyanide leach operations could pose a risk to nearby communities. Rather than relying solely on conservative assumptions or modeling, the U.S. Environmental Protection Agency (EPA) invoked its authority under Clean Air Act Section 114 to request real-world data. In response,… Read more: Science in Support of Smart Regulation: How Air Sciences Helped Shape EPA’s Gold Mining Policy
  • Advanced Wildfire Smoke Tracking for Legal Clarity and Support, Part II
    Rising global temperatures have increased the frequency and intensity of wildfires worldwide, especially in northern and temperate forests. These extreme fires have sparked significant legal claims affecting agriculture, forestry, tourism, and infrastructure. Accurately understanding wildfire smoke dispersion is vital in legal disputes to identify which fires caused specific impacts and to gauge their effects amid… Read more: Advanced Wildfire Smoke Tracking for Legal Clarity and Support, Part II
