The multi-agency and international T-PARC (THORPEX Pacific Asian Regional Campaign) requires the use of the structurally modified Naval Research Laboratory (NRL) P-3 aircraft equipped with the National Science Foundation (NSF) ELDORA radar to investigate tropical cyclones in the Pacific region. <br/><br/>The airborne system, using the ELDORA Doppler radar, will allow for investigation of the short range dynamics and forecasting of one area and its impact on forecasting in a downstream region. The primary purpose of TPARC is to lead to improved predictive skill of high impact weather events such as tropical cyclones.<br/><br/>The observations made by the P-3/ELDORA system will be complemented by observations from other aircraft and sounding systems.
