Remtech PAO Doppler Sodar Upgrade

The U.S. Department of Commerce, NOAA/OAR/ARL/ATDD intends to award on a sole source basis to Remtech, Inc., 2 Red Oak Rd, Saint James, NY 11780, to upgrade ATDD's existing Remtech PAO Dopplar SODAR. The antenna is made of 64 piezo-electric transducers, operating at 3.85 KHz (central frequency). Active antenna size is 40 cm x 40 cm. The minimum measurement height is 15 meters. The average range is 700 meters. The requested upgrade of ATDD's existing Remtech PAO Dopplar SODAR represents a significant advancement in measurement capability and deployment logistics for ATDD's current PAO vertical wind profiling capability. This is an upgrade to existing ATDD PAO SODAR hardware that takes advantage of advances in signal processing and computing capability since ATDD's original purchase. Other ATDD's requirements for remote vertical sounding capability, based on historical field observations conducted by ATDD and in particular those requirements applicable to ATDD's renewable energy field measurement program , include: 1) The SODAR system must operate with the existing ATDD owned extensive REMTECH measurement and analysis software. ATDD has completed multiple investigations to validate the measurement software acquired from Remtech. In addition to the Remtech SODAR operating system, ATDD's signal processing and analysis software suite includes: Vectorial presentation of vertical profile of horizontal wind Facsimile presentation of all data Multi-level time series presentation of all data 6 dB improvement of signal processing. This is equivalent to 4-fold the power output. Extended frequency coding. It gives a signal processing improvement of up to 10 dB (equivalent to 10-fold the output power). Sigma w computation Sigma u and Sigma v computation Sigma theta computation Automatic mixing height/depth calculation 2) Since the SODAR will be use in junction with the ATDD 30-m flux tower system, the SODAR must provide measurements at a minimum height of 20m in order to assimilate the two measurement platforms as well as evaluate measurement accuracies. 3) Based on previous SODAR observations of the nocturnal jet observed at the ATDD's Ocotillo wind farm location, the SODAR must provide an average maximum measurement height of 700m. The average maximum height is based on an average across all atmospheric conditions with the exception of precipitation. 4) The number of vertical levels (gates) (user selectable) must be between 50-100 with a minimum range gate of 10m. 5) The averaging period for reported velocity and turbulence profiles must be user selectable between 10 to 60 minutes 6) The SODAR must be capable of resolving horizontal winds over a speed range between 0 to 30 m/s. 7) The SODAR must be capable of resolving vertical wind speed between a range of-3 to 3 m/s. 8) The SODAR winds speed accuracy should be 0.25 m/s or better. 9) It is critical that the basic instrument footprint for the SODAR transducers and electronic case must be less than <1 m2 with a total weight of transducers and electronics less than 30kg 10) The SODAR must be able to operate on either AC or battery power with basic requirement of 12-24 volts and must be solar capable. 11) The SODAR must be capable of operating in remote environments with ambient operating ambient temperatures between -10degrees C to +40 degrees C. 12) The SODAR system must be capable of remote interrogation through WiFi, ethernet, or wireless cellular modem (wireless modem supplied by ATDD) 13) Due to potential deployment within urban environments, the SODAR system must provide an ambient noise rejection algorithm. 14) Required delivery 30 days ARO. Place of delivery is NOAA/OAR/ARL/Atmospheric Turbulence and Diffusion Division, 456 S. Illinois Avenue, Oak Ridge, TN 37830, USA. Delivery shall be FOB Destination. 15) The offeror must be registered in the Central Contractors' Registry (CCR) and Online Representations and Certifications (ORCA). DUNS # to be provided.
