Data In 'Development At The University Of North Dakota Of A Digital Thermosonde Instrument For The Study Of Atmospheric Optical Turbulence (C_N^2)', Blake T. Sorenson, David J. Delene

Datasets

A thermosonde, an instrument that measures very high resolution temperature difference between two fine-wire platinum thermocouples, was attached to a weather balloon and lifted through the atmosphere, collecting observations of optical turbulence, in the spring of 2018 and 2019. The thermosonde collected raw temperature difference measurements, while an onboard Graw DFM-09 radiosonde observed standard meteorological parameters (temperature, air pressure, wind speed, wind direction, relative humidity, and altitude). The Graw meteorological observations are housed in the .txt files, while the raw radiosonde data (containing the raw, encoded thermosonde measurements) are housed in the .gsf files. The decoded voltage and temperature difference …

Analysis Of Concurrent Backscatter Coefficients From In-Situ Cloud Probes And Airborne Lidar, Shawn Wagner, David J. Delene

Datasets

The North Dakota Citation Research Aircraft obtained measurements of anvil cirrus clouds over Florida during the summer of 2015 (CAPE2015). The Citation is fitted to take measurements of atmospheric variables (pressure, temperature, dew point, wind velocity, etc...) as well as cloud particle properties (concentration, size-distribution, water content, etc...). Data (at 1 Hz) is included from four flights occuring on 31 July 2015, 1 August 2015, and 2 August 2015. Cloud properties were measured by the Two-Dimensional Stereo probe (2D-S), the High-Volume Precipitation Spectrometer (HVPS3) probe and the Nevzorov probe. Additionally, particle data from the 2D-S and HVPS3 are combined to …

A Multi-Platform, In-Situ Kinematic And Microphysical Analysis Of A Parallel Stratiform-Mesoscale-Convective System, Andrea Neumann, Michael Poellet, David J. Delene, Mark Askelson, Kirk North, Mariko Oue

Datasets

The North Dakota Citation Research Aircraft obtained measurements of stratiform precipitation clouds within mesoscale convective systems over Oklahoma during the spring of 2011 (MC3E) in conjunction with a multitude of ground- and airborne-based remote sensing instruments. The Citation was used to take measurements of base atmospheric variables as well as cloud and precipitation properties. Cloud droplet properties were measured by the Cloud Imaging Probe (CIP), Two-Dimensional Cloud probe (2D-C), the High-Volume Precipitation Spectrometer Version 3 (HVPS3) probe, with the spectra from these probes combined to create a single drop size distribution. The Atmospheric Radiation Measurement (ARM) program ran three X-Band …

Software For Conformal Boundary Operators, T-Curvatures, And Conformal Fractional Laplacians Of Odd Order, Lawrence Peterson

Datasets

The author has developed some new computer software and has used it, together with Mathematica and John M. Lee's Ricci software package, to construct and verify many of the symbolic formulae in the article "Conformal boundary operators, T-curvatures, and conformal fractional Laplacians of odd order," by the author and A. Rod Gover. This software is posted here, along with the Ricci package.

The author has also prepared a special guidelines file describing the new software. This guidelines file briefly describes Mathematica and Ricci as well. One should read Section 3 of the guidelines file before saving the main software file …

Snow Depth Data, Xuefeng Michael Chu Ph.D, Kendall Grimm, Mohsen Tahmasebi Nasab, Ning Wang, Mohammad Hadi Bazrkar, Lan Zeng, Matt Lee, Jamal Ghauri, Dillon Ekholm, Jackie Arntson, Libby Kruse, Jared Swanberg

Datasets

Ten precipitation stations were set up to collect precipitation data (including rainfall/snowfall and snow depth measurements) across 6 USGS HUC10 watersheds. The ultrasonic snow depth sensor was utilized to obtain continuous and non-contact snow depth measurements (Ultra Sonic Snow Depth Sensor (USH-8), Hydrological Services America). Data accuracy is within 0.1% due to the integrated temperature compensation and filtering of snow and rainfall using intelligent spectrum analysis. However, the sensor does pick up any vegetation beneath the sensor. Thus, the snow depth data were processed. See the ReadMe file for complete details located in the zip file of snow depth data.

Spatially Distributed Pothole Depth Data, Xuefeng Michael Chu Ph.D, Kendall Grimm, Mohsen Tahmasebi Nasab, Ning Wang, Mohammad Hadi Bazrkar, Lan Zeng, Matt Lee, Jamal Ghauri, Dillon Ekholm, Jackie Arntson, Libby Kruse, Jared Swanberg

Datasets

The locations of our surveyed potholes are located in the Cottonwood Lake Study Area (CLSA) of the USGS Northern Prairie Wildlife Research Center (NPWRC). RiverSurveyor M9 by SonTec (RiverSurveyor M9) was utilized to obtain spatially distributed pothole depth data. This way a modified DEM was created which reflected the pothole bathymetry rather than the water surface elevations. The M9 records water depths using multi-band multiple acoustic frequencies from the vertical beam which “pings” the pothole bed while simultaneously collecting the GPS coordinates of each “ping”. High ping rates ensure robust data collection and high resolution. The vertical beam can measure …

Precipitation Data, Xuefeng Michael Chu Ph.D, Kendall Grimm, Mohsen Tahmasebi Nasab, Ning Wang, Mohammad Hadi Bazrkar, Lan Zeng, Matt Lee, Jamal Ghauri, Dillon Ekholm, Jackie Arntson, Libby Kruse, Jared Swanberg

Datasets

Ten precipitation stations were set up to collect precipitation data (including rainfall/snowfall and snow depth measurements) across 6 USGS HUC10 watersheds. The heated tipping bucket rain gauge was utilized to obtain precipitation measurements. The heating mechanism engaged when temperatures were below freezing and thawed frozen precipitation to acquire measurements year-round (Heated Tipping Bucket Rain Gauge, Hydrological Services America). The data accuracy is within +/- 3% even with high rainfall intensities due to the integrated syphon mechanism which controls the release of precipitation into the tipping bucket (TB3 Tipping Bucket Rain Gauge, Hydrological Services America). The data were originally collected at …
