66 -- OZONESONDES SOL NRMGP100900123MB POC Michelle Bernal, Purchasing Agent, (303) 497-3983 or FAX (303) 497-3163 E-MAIL: NOAA; MASC Acquisition Management, bid.tech@noaa.gov. The National Oceanic & Atmospheric Administration(NOAA) proposes to negotiate on a sole source basis contract under the authority of 41 U.S.C. 253(c)(1) with ENSCI Inc. for ozonesondes. Critical specifications are as follows: (1) Sensor for detecting ozone must be of the electrochemical concentration cell (ECC) type. (2) Pump must be non-reactive with ozone and capable of working in the altitude range of 0 to 35 km. A thermistor for measuring pump temperature must be mounted in the pump. (3) Ozonesonde must be capable of measuring ozone with an accuracy and precision of 5 percent over the altitude range of 0 to 30 km and for ozone mixing ratios of 0 to 15 parts per million by volume. (4) Ozonesonde must provide an electronics interface with the Vaisala RS-80 radiosonde with the following characteristics: (a)Capable of mounting within the chassis of the ozonesonde and interconnecting with the sensor output and the pump thermistor with all connections provided. (b)Provide power source (battery) for interface board and pump operation. (c)Capable of providing 1 second data output. (d)Sensor current must be read with 12 bit accuracy. (e)Be able to provide conversion of the Vaisala RS-80 pressure, temperature and humidity information as well as the ozonesonde sensor current and pump thermistor resistance and produce a data stream that can be transmitted by the RS-80 radiosonde. (f)Be compatible with the NOAA Climate Monitoring and Diagnostics Laboratory ozonesonde software and data processing routines. (5) Ozonesonde must be housed in a container that maintains the environmental conditions in the temperature range 10 to 30 degrees Celsius. (6) The ozonesonde and its container must weigh 1.0 kilogram or less. This procurement is being conducted per FAR Part 13, Simplified Acquisition Procedures.
