Purpose: RADEX-15 Science Mission #2 – Sample pre-frontal and frontal clouds. Comments: Flight 16-9019 was the second science mission from KTCM with AMPR, CPL, eMAS, HIWRAP and EXRAD. Flight 16-9019 took off on time from KTCM at 0602 local and landed in KTCM at 1414 local (8.2 hours). Stu Broce was the pilot. After gaining altitude, an initial 100 Nm racetrack with a 12 Nm offset parallel to the 500 mb flow was flown basing on a point offshore due west of Ozette. This initial racetrack was reoriented more north-south with the cloud bands evident in the IR imagery. This racetrack was flown several times in coordination with the DC8 beginning around 1600 UTC. The Citation joined the pattern at ~1625 UTC and did a series of stepped ascents and spirals near the northern end of the racetrack. During this initial phase, precipitation transited closer to the racetrack. Satellite imagery showed the cloud band associated with the front becoming broader and colder with time. The Citation landed at Port Angeles to refuel and the ER2-DC8 racetrack was reoriented NW-SE with an eastern point centered on the NPOL radar. This race track was flown across the cloud bands associated with the front for the remainder of the flight as surface rain approached the coast. The Citation rejoined the racetrack and conducted stepped legs offshore after 2130 UTC. The ER2 and DC8 departed the race track at approximately 2140 UTC. The ER2 landed at 2214 UTC. The Citation continued collecting in situ data for 1.5 more hours. All instruments performed nominally with the exception of HIWRAP and CRS that was reset early in the mission. Some data was lost near the end of the mission by CRS and HIWRAP when storage space ran out. Data during the last 10-20 minutes of the flight was collected successfully.
