Mr. Klausmann is a Certified Consulting Meteorologist with more than 25 years of experience in the areas of air quality and applied meteorology. Mr. Klausmann is experienced with the CALMET/CALPUFF modeling system, the AERMOD dispersion model, mesoscale meteorological modeling using MM5 and WRF, and meteorological data analysis. He has performed air quality impact assessments and meteorological studies to support permitting, environmental impact reports, siting and feasibility studies, consequence analysis for potential hazardous chemical releases, and nuclear emergency preparedness. He has performed CALMET and CALPUFF modeling studies for various industrial facilities for both near-field air quality studies and long-range transport modeling for visibility impact studies.

Mr. Klausmann has performed MM5 modeling for development of high-resolution three-dimensional data sets, to support building damage studies for high-impact weather events, and real-time forecasting applications. He worked extensively with the WRF numerical model both for creating high-resolution data sets for air quality modeling as well as hurricane modeling. Mr. Klausmann has been active in developing meteorological service capabilities for wind energy and has worked on several small wind resource assessment studies. He has also conducted several forensic meteorological studies for several projects across the United States.

Project Experience

Conducted multi-year WRF four dimensional data assimilation simulations for a domain over British Columbia, Canada. This work is to support a complex CALPUFF modeling study.

Implemented the polar optimized version of the Weather Research and Forecast (WRF) model and completed a one-year test simulation over Victoria Island, Canada. Completed a model evaluation through comparisons with surface observations.

Completed MM5 simulations for a 5-year period over Victoria Island region of Canada to create a multi-year gridded data set for CALPUFF modeling applications in the region. Conducted extensive sensitivity analysis and a model performance evaluation.

Performed WRF Four Dimensional Data Assimilation simulations to create a high resolution gridded meteorological data sets over the southeastern United States. Extensive testing was conducted to examine model predictions of wind, temperature, and rainfall using several Planetary Boundary Layer and Cumulus parameterization schemes.

Conducted extensive retrospective WRF simulations to perform an analysis of the surface wind field and rainfall of Hurricane Irene during its track along the U.S East coast. Conducted a model performance analysis using microwave satellite imagery, NOAA regional precipitation analyses, and making comparisons with the NOAA Hurricane Research Divisions H*Wind product.

Worked on a detailed CALPUFF/CALMET modeling analysis of the European Transport Experiment to support model evaluation efforts.

Conducted a meteorological analysis and prepared an expert report for the Susquehanna River Flooding Event of September 7-8, 2011. This involved a synoptic and mesoscale analysis using a variety of analysis data, satellite and radar imagery to describe the evolution of events that resulted in the flooding.

Developed a CALMET-ready three-year RUC data set for a large domain centered over North Dakota using NCEP hourly RUC analysis files. Performed a detailed evaluation to assess the overall quality of the data set using available surface and upper air observations. This involved computing various performance statistics and comparing these statistics with established performance benchmark criteria.

Performed a screening-level wind resource assessment. The objective of this analysis was to use available data to determine the viability of installing wind turbines at selected sites in Massachusetts and New Jersey. The approach involved assembling available wind resource maps of specific areas, as well as available surface hourly observations. A statistical analysis of the available surface meteorological observations was performed, and comparisons were made with data from the available wind maps.

Conducted CALMET and CALPUFF modeling to determine air quality impacts due to emissions from a proposed coal-fired boiler. Worked on development of the MM5 model setup and testing strategy for multi-year FDDA simulations. Performed extensive CALPUFF simulations and conducted a detailed analysis of PM10, PM2.5, and SO2 impacts for a range of design scenarios and facility modifications.

Performed high-resolution MM5 simulations of hurricane Katrina. Work involved conducting numerical simulations using the MM5 model using nested grids down to a spatial resolution of 2 km to study the evolution of the inner-core wind field as the hurricane made landfall. Results of the analysis were then used to support Computational Fluid Dynamics modeling to study the wind flow around building structures in the New Orleans urban area. This work was performed to support building damage assessments.

Conducted CALMET and CALPUFF modeling to assess the air quality and visibility impacts at two Class I areas in northwest Florida due to emissions from a proposed coal-fired power plant. Work involved determining air quality impacts at the Bradwell Bay Wilderness Area, and both air quality and visibility impacts at the St. Marks Wilderness Area.

Performed MM5 four dimensional data assimilation simulations over Brazil to support development of a high-resolution meteorological data set to be used for CALMET/CALPUFF modeling. The objective was to evaluate air quality impacts from industrial facilities in Pocos De Caldas and Sao Luis, Brazil.
