WebWe plan to present the following two experiments. First, we will assimilate OMI NO2 to constrain NOx emissions over the western U.S. and validate against observations from the FRAPPE campaign (July 2014) measurements to demonstrate the benefit of assimilating remote sensing NO2 for improving air quality forecast. WebThis project used two methods: (1) comparing satellite data to high resolution (<12 km2) model simulations and (2) comparing bottom-up emission inventory estimates to satellite-derived estimates from urban areas and power plants.
