Doppler Lidar

DESCRIPTION The Department of Commerce (DOC) National Oceanic and Atmospheric Administration (NOAA) National Severe Storms Laboratory (NSSL) has a requirement for a Doppler Lidar. NOAA is not seeking vendors to design, develop, and then produce this requirement; we are seeking vendors already capable of providing a working solution. NSSL requires a Doppler Lidar to better understand how environmental factors that are characteristic of the southeast United States affect the formation, intensity, and storm path of tornadoes for this region. One of the key issues requiring further study is how phenomena in the low-level environments of thunderstorms, such as waves and small-scale fronts, are related to tornado formation. The minimum salient characteristics for the Doppler Lidar include the following: - The ability to provide line-of-sight wind speed and intensity estimates at 1 Hz or faster. - Processing gate size has to be 30 m or shorter. - Laser pulse width of 200 ns or shorter. - Full hemispheric scanning o 0-360 degrees in Azimuth o -10 to 109 degrees in Elevation - Must have continuous scan mode capability (as opposed to only step and stare) - Continuous scans must have the following properties o Azimuthal scans: ? The ability to select and initial and final azimuthal angle. ? The ability to select an azimuthal scan speed ? The ability to select a series of fixed elevation angle at which to perform the azimuthal scans o Elevation scans: ? The ability to select and initial and final elevation angle ? The ability to select an elevation scan speed ? The ability to select a series of fixed azimuth angle at which to perform the elevation scans o Coordinate scans: ? The ability to specify a sequence of azimuth and elevation coordinates, the azimuth and elevation scan rates to while scanning to them, and the time to dwell at each coordinate. - The system must have a scan queue with the following properties: o Controllable via the Internet o Must have the ability to program and control a sequence of continuous scans (as opposed to only a sequence of step and stare scans) o Must have the ability to automatically switch between preselected scan queues depending on the time of day - for at least 8 pre-selected times during the day. (For example daytime mode vs nighttime mode) - The instrument must be eye safe at the beam aperture - The instrument must have a sealed environmental enclosure and has to operate under ambient temperatures ranging from -15 to + 40 C. - The system must have Nyquist velocity of at least 18 m/s - Minimum range for scientific utility: 60 m (i.e., first usable measurement must be made at this range or at a shorter range) - Maximum range: 9 km - The system has to operate autonomously and needs to be remotely controllable via an Internet connection - The system must have a real-time processor that calculates and displays range resolved estimates of line-of-sight velocity and intensity. - Types of data displays required: o AScope: single beam line plot o RTI: Range-time indicator displays o Polar: Displays for scanning data - The instrument will have at least a one-year warranty - Processed Data format: o The lidar system must create and store files of processed data to the disk o These files will contain range resolved estimates of radial velocity and signal to noise ratio o Each profile of estimates will be time tagged o Each file will contain information on site location and processing parameter o If the processed data files are binary, the format of the files will be provided so that NOAA/NSSL can develop computer programs to read these files - Noise data format: o If the system takes automatic noise files, these files will be saved so that they can be used in re-processing o If the noise data files are binary, the format of the files will be provided so that NOAA/NSSL can develop computer programs to read those files - Demonstrated capability: The vendor must have produced and sold a sufficient number of units so that their performance in the field can be evaluated. - The physical size must be no larger than 32 inches by 31 inches (length by width), and weigh less than 200 lbs.
