V -- AIRCRAFT SERVICES SOL 52RANR900026 DUE 051399 POC Procurement Technicians, 303/497-3221 The National Oceanic and Atmospheric Administration (NOAA) will be partici- pating in the Southern Oxidants Study this Summer (June 15-July 15, 1999) in Nashville, TN. In particular, NOAA will be deploying an airborne UV- DIAL ozone lidar in this study. The UV-DIAL ozone lidar is an instrument that is used to make measurements of ozone concentrations in the lower atmosphere. This study is one of the largest studies of its kind being conducted to investigate the development and evolution of photochemical pollution in urban and surrounding areas. An aircraft suitably equipped to accommodate the instrument to be used in the field study is required. The aircraft must be fully ready, with the instrument installed before the study start date of June 15, 1999 for coordination with many other researchers and instruments. The aircraft shall be able to accommodate the following: (1) The cabin of the aircraft shall be of a size to allow the equipment to fit with adequate room left for operator access to the instrument and clear egress. The system is composed of four units with dimensions of 42"W x 108"L x 65"H laser and optics frame; 28"W x 28"L x 30"H power distribution unit; 2@40"W x 27"L x 45"H data acquisition units; (2) The aircraft shall have a clear opening larger than 22"W x 26"L in the underside of the aircraft; (3) The door to the cabin shall be sufficiently wide and tall and appropriately located to allow installation of the system in a level orientation; (4) Flights may be conducted at altitudes from 3000 to 13000 feet AGL; (5) Flight durations may be up to 4 hours; (6) The total weight of the instrument package and operators will be 2,000 to 2,200 pounds; (7) The aircraft shall be able to fly at a speed less than or equal to 200 mph; (8) The electrical power available to the instrument shall be at least 150 Amperes of 28 Volts DC; (9) There should be access to attach a GPS antenna on the aircraft for positioning information gathered by the instrument; (10) The cabin shall accommodate seats for up to 3 instrument operators on board and provide communications between the instrument operators and flight crew during the flight; (11) Any aircraft modification required as well as the instrument installation shall be approved by a FAA Designated Engineering Represenative for safety; (12) The aircraft and the installation of the instrument shall be in compliance with all applicable FAA rules and regulations and must carry survivial equipment for all passengers appropriate to the operating environment. There is an estimated 64 flight hours that will be conducted from June 15, 1999 to July 15, 1999. The installation of the instrument before the study and the removal of the instrument at the end of the study shall be done by the aircraft provider and NOAA personnel at a site mutually agreed upon. The transportation of the aircraft with instrument and crew to Nashville, TN shall be provided by the Contractor. The firm selected must be a nationally recognized company with a good reputation throughout the industry. See Numbered Note 1. Posted 04/07/99 (W-SN317392). (0097)
