1.6.1 Scientific expertise <br />The scientific expertise behind the SOAR research aircraft is based on the extensive experience of Dr. <br />William Woodley and Prof. Rosenfeld in weather modification research. Dr. William L. Woodley, President <br />of Woodley Weather Consultants in Littleton, Colorado, and Prof. Daniel Rosenfeld of the Hebrew <br />University of Jerusalem in Jerusalem, Israel, served as the co-Principal Investigators, Flight Scientists <br />and overall coordinators of the multi-faceted effort. Drs. Woodley and Rosenfeld have worked together as <br />a research team for over 20 years. They share common interests in the measurement of cloud properties <br />and rainfall using aircraft, radar and satellite platforms and in cloud seeding for rainfall enhancement. <br />Dr. Don Collins and Dr. Joshua Santarpia from the Texas A&M University Aerosol Research Group acted <br />as instrument mentors for the Tandem Differential Mobility Analyzer (DMA/TDMA) system. Mr. Ronen <br />Lahav provided some support in the field for about one week while Dr. Rosenfeld was committed to a <br />meeting outside the US. <br />1.6.2 Flight Meteorologist/Instrument operator <br />Additional scientific expertise was provided by Mr. Duncan Axisa who is the Project Director and lead <br />Meteorologist for the SOAR program. Mr. Axisa is experienced in the operational aspect of weather <br />modification including hands on day-to-day running of precipitation enhancement programs. Duncan <br />Axisa served as the Flight Meteorologist on all flights and as Instrument operator on board the SOAR <br />research aircraft. This duty included the planning of all research flights, coordinating with other members <br />of the research team on a daily basis and ensuring the data collection of each flight during the contract <br />period. Mr. Axisa coordinated with the Project Meteorologist on the research team and with the Principal <br />Flight Scientists to plan the flight sorties during the contract period. When a flight was launched, Mr. Axisa <br />was on board the SOAR research aircraft directing the flight operations and ensuring the collection of <br />data by the instrumented platform. <br />1.6.3 Project Meteorologist/Radar Meteorologist <br />Mr. Caleb Midgley provided ground support for the SOAR research aircraft. Mr. Caleb Midgley was a <br />contract Project Meteorologist/Radar Meteorologist for the SOAR program and responsible for the day-to- <br />day operations of the precipitation enhancement program in the SOAR target area during the contract <br />period. Mr. Midgley was responsible for issuing weather forecasts and their dissemination, with his area of <br />expertise being mesoscale meteorology and convective storm structure. Mr. Midgley was also responsible <br />for documenting the synoptic and mesoscale environment for the case study days during SPECTRA 1. <br />1.6.4 SOAR research aircraft pilot-in-command <br />The SOAR research aircraft was piloted by Mr. Gary Walker. Mr. Walker holds a Commercial Pilot <br />License Multi Engine Land Instrument certification. Mr. Walker has flown thousands of hours in the state <br />of Texas with a few hundred of those hours being in cloud seeding operations and research projects. <br />Gary Walker has a lot of experience flying in Instrument Meteorological Conditions or in conditions when <br />the pilot-in-command is flying in marginal weather conditions and flying the airplane solely on the aircraft <br />instruments. Mr. Walker has flown weather modification missions for the past nine years. <br />1.6.5 Aircraft mechanic <br />The SOAR aircraft mechanic during SPECTRA 1 was Mr. Dave Davalos. Mr. Davalos is the Director of <br />Maintenance with Aero Systems Inc. (ASI). ASI has developed systems for research aircraft operations <br />on the FACE, SCPP, BEWMEX, HIPLEX and CCOPE projects, as well as systems for air quality <br />monitoring and marine survey projects. <br />16 <br />
