CLAMPS NWC/RIL Observations

CLAMPS observations from CLAMPS1 during a local/internal deployment to restart operations after COVID19 pause of deployments. CLAMPS2 did not deploy. These datasets include boundary-layer profiles of wind, temperature, and humidity collected from the CLAMPS system.  These data can be accessed on the <a href="https://data.nssl.noaa.gov/thredds/catalog/FRDD/CLAMPS/campaigns/PBLtops/catalog.html">NOAA National Severe Storms THREDDS Archive</a>. The readme contained here provides information about how to access and available resources for users.  After a full pause of all observation activity due to the COVID19 pandemic, the CLAMPS1 facility was deployed just outside the National Weather Center in Norman, OK to restart observation practices. The location is between the National Weather Center and the OU Radar Innovations Laboratory and directly adjacent to the KOUN NWS-Norman Sounding release location. Observations are generally continuous throughout the period, though some non-standard scan and operations modes may be included as a result of tests conducted by the operations team during the deployment.

PBL Tops CLAMPS observations

CLAMPS observations from both CLAMPS1 and CLAMPS2 during PBL Tops: Evaluating Polarimetric Retrievals of Boundary Layer Height Using State-of-the-Art Boundary Layer Profiling, a project supported by OU/CIWRO's Director's Discretionary Funds. Details about the instruments onboard CLAMPS can be found on the <a href="https://apps.nssl.noaa.gov/CLAMPS/instrumentation.php">NSSL CLAMPS</a> webpage. These datasets include boundary-layer profiles of wind, temperature, and humidity collected from the CLAMPS systems. These data can be accessed on the <a href="https://data.nssl.noaa.gov/thredds/catalog/FRDD/CLAMPS/campaigns/PBLtops/catalog.html">NOAA National Severe Storms THREDDS Archive</a>. The readme contained here provides information about how to access and available resources for users.  Observations cover a 4-week observation period, split into two 2-week blocks. During block 1, each CLAMPS will deploy near KTLX (Norman, OK) at a radar-adjacent site (0-5 km) and a radar-distant site at Kessler Atmospheric and Ecologial Field Station (10-20 km), respectively. During block 2, the radar-distant CLAMPS will reposition to a radar-adjacent site at KSHV (Shreveport, LA). The observational approach providess one continuous 4-week time series within 5 km of KTLX. By moving the second CLAMPS platform between the two blocks (from Kessler Station to KSHV), the data can be used to evaluate differences due to distance from radar and the local climatology or land-use characteristics, which may modify expected boundary-layer evolution.  Owing to the sparse distribution of atmospheric profilers, numerous studies have sought to use radar detection of Bragg scattering to observe the evolution of planetary boundary layer (BL) height, including efforts using the operational NWS WSR-88D network by Banghoff et al. (2018; hereafter B18) using. The B18 method uses quasi-vertical profiles obtained from azimuthal averaging (Ryzhkov et al. 2016) and offers the promise of national, real-time estimates of BL height. However, the B18 method was only initally validated using twice-daily radiosonde observations, thus obscuring its efficacy for retrieving BL height estimates during periods of evolution and complex structure (e.g., morning/evening transitions, residual layers, etc.). The observations in this dataset were collected in an effort to (1) validate the polarimetric B18 method using specialized independent measurements from both CLAMPS; (2) extend validation times to include important BL evolution periods beyond synoptic sampling times and identify failure periods and regimes; (3) contextualize and interpret signatures observed in B18 using novel near-continuous data (e.g., overnight signatures); and (4) quantify the skill of the B18 method.

CHEESEHEAD CLAMPS observations

The Chequamegon Heterogeneous Ecosystem Energy-balance Study Enabled by a High-density Extensive Array of Detectors (CHEESEHEAD) experiment was conducted near Falls Park, Wisconsin in mid-summer to early fall 2019 (Butterworth et al., 2021). Primarily sponsored by the National Science Foundation, additional support from NOAA enabled the concurrent deployment of CLAMPS1 and CLAMPS2 at Lakeland and Prentice airports, respectively, for approximately five weeks of data collection. CHEESEHEAD also included radiosonde launches near the WLEF-TV 400-m very tall tower site, which was approximately 45 km away from both CLAMPS locations (north of Prentice, west of Lakeland) and many other instruments. There are additional observations after this time, but the main period of quality data is 19 September 2019 to 10 October 2019. These data can be accessed on the <a href="https://data.nssl.noaa.gov/thredds/catalog/FRDD/CLAMPS/campaigns/PBLtops/catalog.html">NOAA National Severe Storms THREDDS Archive</a>. The readme contained here provides information about how to access and available resources for users. These data are also published in the CHEESEHEAD EOL catalog. The CLAMPS1 (located at Lakeland Airport, 45.92◦ N, 89.73◦ W) DL collected plan position indicator (PPI) scans at 70 ◦ elevation every 20 minutes, and remained in a zenith pointing mode otherwise. The DL provides range-resolved, line-of-sight measurements of radial velocity, intensity (signal-to-noise ratio [SNR]+1), and attenuated backscatter. In the case of PPI scans meant for velocity azimuthal display (VAD) analysis, these data are post-processed to produce profiles of horizontal wind speed and direction. The zenith pointing scans are used for vertical velocity information, and are post-processed to provide turbulence information such as vertical velocity variance. The DL was configured to provide profiles with 18-m vertical spacing. The CLAMPS1 MWR and AERI were both deployed, and thermodynamic profiles as retrieved by the TROPoe physically based algorithm (previous versions known as AERIoe; Turner and Löhnert, 2014) were made available every ten minutes. For different user needs and use cases we provided retrievals using only AERI data, only MWR data, and combining the data from both the AERI and the MWR in the TROPoe retrieval algorithm. The CLAMPS2 facility (located at Prentice Airport, 45.54◦ N, 90.28◦ W) operated similarly, but the DL collected PPIs at 60 ◦ elevation every 5 minutes. The onboard MWR was deployed similarly, but CLAMPS2’s AERI was damaged in transit and did not operate for CHEESEHEAD. As such, CLAMPS2 retrievals are limited to MWR-only.  Turner, D.

In situ clamped beam bending of accumulative roll bonded Cu/Nb with 16 nm individual layer thickness

In situ scanning electron microscope (SEM) videos of clamped beam bending of Cu/Nb ARB nanolaminates with 16 nm layer thickness. Each video contains the video captured with SEM and the corresponding measured load vs. displacement curve. The beams were fabricated using focused ion beam (FIB) milling from bulk Cu/Nb sample produced in Los Alamos National Lab, USA. The sample was made using accumulative roll bonding (ARB) process, described in ref. [1].  All the beam lengths are aligned with rolling direction (RD) of the sample. Each beam has a rectangular notch located in the center of the beam length. Each notch spans through the beam width.  Owing to limited accuracy of FIB, the notch depth was not always same at the front and rear sides of the beam (typically, smaller at the rear sides) Beam geometries: Id | Length, µm | Width, µm | Thickness, µm | Notch depth (front), nm | Notch width (front), nm ARBRD1 | 40 | 4.9 | 4.2 | 800 | 180 ARBRD2 | 40 | 5.1 | 2.4 | 350 | 160 All the beams were loaded using Hysitron PI85 picoindenter with truncated cone shape (5 µm diameter). The indenter tip was aligned with the notch location and the middle of beam width.  All the beams were loaded under displacement control with displacement rates between 2nm/s to 10nm/s until failure. The SEM videos were captured using JEOL JSM-7600F SEM.  [1] Irene J Beyerlein et al. “Interface-driven microstructure development and ultra high strength of bulk nanostructured Cu-Nb multilayers fabricated by severe plastic deformation”.
