Wind profile data from NOAA LIDAR measurements

The NOAA Profiler Network (NPN) radars provide vertical profiles of horizontal wind speed and direction from near the surface to above the tropopause. The system also generates data quality related statistics such as signal-to-noise ratio (SNR) and spectrum width. There are three systems in Alaska (Talkeetna, Anchorage, and Homer), with an additional testbed site in Norman, OK. The location and ICAO ID for the NOAA NPN sites are: Norman, OK - ROCO2/KROC; Homer, AK - HWPA2/KHWP; Talkeetna, AK - TLKA2/KTLK; and Anchorage, AK - AWPA2/KAWP. Each wind profiler unit uses preprogrammed operational modes to determine the speed and direction of the wind at different heights directly above the unmanned radar site. This dataset covers the newly refreshed NPN upper air wind data, beginning with 2020. A previous NPN project covered 1991 - 2006 and is available in BUFR format for winds, moments, RASS, and surface file types.

**Overview** These profiling lidar datasets collect profiles of wind speed and wind direction from nominally 40 m above the surface to 220 m above the surface, depending on visibility. **Data Quality** Only data points with CNR -22 dB are included in these 2-min averaged files.

**Overview** The available "readme" file introduces the basics of the Doppler lidar data and offers a detailed description of the variables present in the data files. For those with any further questions about the data and its interpretation, contact either Alan Brewer () or Sunil Baidar (). It is highly recommended to discuss any planned use of the data with National Oceanic and Atmospheric Administration-Chemical Sciences Division (NOAA-CSD) scientists. For more information, refer to the Readme file: "noaa-esrl-arlingtonlidar-readme-1.pdf." **Data Quality** Refer to the attached "noaa-esrl-arlingtonlidar-readme-1.pdf" Readme file. **Uncertainty** Refer to the attached "noaa-esrl-arlingtonlidar-readme-1.pdf" Readme file. **Constraints** Refer to the attached "noaa-esrl-arlingtonlidar-readme-1.pdf" Readme file.

**Overview** Wind and lidar turbulence profiles from 40 m to 220 m above the surface. **Data Quality** These two-minute-averaged data files consider the 1 Hz line-of-sight measurements that pass the -22 dB CNR quality control threshold. **Uncertainty** Line-of-sight measurements are converted to horizontal wind speed by assuming horizontal homogeneity in the measurement volume (as discussed in several publications, including Rhodes and Lundquist 2013 and Lundquist et al. 2015). In inhomogeneous flow, this assumption may not be valid. These instruments were sited to avoid breaking the horizontal inhomogeneity assumption, although the Gordon's Ridge sight may be problematic in this respect.

The NARSTO_SOS99NASH_WIND_PROFILER_DATA were obtained between May 19 and August 4, 1999. Wind components (u and v) were collected from five 915-MHz radar wind profilers. Availability of data for each day varies among the profilers, especially at the beginning and end of the project.The profilers and their locations were:Cornelia Fort Airpark (CFA) 36.19N, 86.70 W, 126 m MSLDickson (DIK) 36.25N, 87.37W, 225 m MSLEagleville (EGV) 35.73N, 86.60W, 228 m MSLGallatin (GAL) 36.33N, 86.40W, 171 m MSLCumberland (CMB) 36.38N, 87.65W, 136 m MSLThe number and location of range gates (vertical location of the wind measurements) was:CFA: 1st gate 146 m AGL, 64 gatesDIK, EGV, GAL: 1st gate 96 m AGL, 50 gatesCMB: 1st gate 165 m AGL, 64 gatesAll sites use 58 m range gates.Mixing depth (convective boundary layer height or zi) is given for daytime hours at each site as derived from a manual inspection of profiler reflectivity patterns. Data may be unavailable for a variety of reasons including rain, poorly defined boundary layer, or instrument outage. Data in late afternoon should be used with care even when available, since the afternoon transition is poorly understood.NARSTO (formerly North American Research Strategy for Tropospheric Ozone) is a public/private partnership, whose membership spans government, the utilities, industry, and academe throughout Mexico, the United States, and Canada. The primary mission is to coordinate and enhance policy-relevant scientific research and assessment of tropospheric pollution behavior; activities provide input for science-based decision-making and determination of workable, efficient, and effective strategies for local and regional air-pollution management. Data products from local, regional, and international monitoring and research programs are available.

The GRIP Doppler Aerosol WiNd Lidar (DAWN) Dataset was collected by the Doppler Aerosol WiNd (DAWN), a pulsed lidar, which operated aboard a NASA DC-8 aircraft during the Genesis and Rapid Intensification Processes (GRIP) field campaign. he major goal was to better understand how tropical storms form and develop into major hurricanes. NASA used the DC-8 aircraft, the WB-57 aircraft and the Global Hawk Unmanned Airborne System (UAS), configured with a suite of in situ and remote sensing instruments that were used to observe and characterize the lifecycle of hurricanes. This campaign also capitalized on a number of ground networks and space-based assets, in addition to the instruments deployed on aircraft from Ft. Lauderdale, Florida ( DC-8), Houston, Texas (WB-57), and NASA Dryden Flight Research Center, California (Global Hawk). Data values include Line-of-Sight (LOS) Winds, calculated vertical profiles of horizontal wind velocity, frequency-domain signal energy and time versus latitude and longitude. Instrument details can be found in the dataset documentation. Data was gathered during August 24, 2010 thru September 22, 2010 over the Atlantic Ocean.
