ACCEPTED FEBRUARY, 2021 1 Bi-directional Domain Adaptation for Sim2Real Transfer of Embodied Navigation Agents Joanne Truong1 and Sonia Chernova1;2 and Dhruv Batra1;2 Abstract—Deep reinforcement learning models are notoriously This raises a fundamental question – How can we leverage data hungry, yet real-world data is expensive and time consuming imperfect but useful simulators to train robots while ensuring to obtain. The solution that many have turned to is to use that the learned skills generalize to reality? This question is simulation for training before deploying the robot in a real environment. Simulation offers the ability to train large numbers studied under the umbrella of ‘sim2real transfer’ and has been of robots in parallel, and offers an abundance of data. However, a topic of much interest in the community [4], [5], [6], [7], no simulation is perfect, and robots trained solely in simulation [8], [9], [10]. fail to generalize to the real-world, resulting in a “sim-vs-real In this work, we first reframe the sim2real transfer problem gap”.

As the formal instrument for wind measurement, ground-based anemometer, radiosonde, Doppler radar and Wind Profiler are utilized so far. However, it is quite difficult to scan the three dimensional (3D) wind field including zenith, and only Doppler radar can be utilized to measure 3D wind speed and direction in the case of rainfall. In recent years, Doppler LIDARs have been developed and it can scan 3-D wind field even in the case of fine weather and is proceeded to be utilized in a variety of fields. Therefore, it is possible to implement all-weather wind measurement with the set of Doppler LIDAR and Doppler radar and this set is much effective to Fig. 6 Wind shear detection system monitor the safety of air at the airport, launch complex and other fields.

    Available online at www.sciencedirect.com ScienceDirect Energy Procedia 53 ( 2014 ) 214 – 220 EERA DeepWind’2014, 11th Deep Sea Offshore Wind R&D Conference A comparison of LiDAR and radiosonde wind measurements Valerie-M. Kumera, Joachim Reudera, Birgitte R. Furevika,b aGeophysical Institute, University of Bergen, Allegaten 70, 5007 Bergen, Norway bNorwegian Meteorological Institute, Allegaten 70, 5007 Bergen, Norway Abstract Doppler LiDAR measurements are already well established in the wind energy research and their accuracy has been tested against met mast data up to 100 m above ground. However, the new generation of scanning LiDAR have a much higher range and thus it is not possible to verify measurements at higher altitudes. Therefore, the LiDAR Measurement Campaign Sola (LIMECS) was conducted at the airport of Stavanger from March to August 2013 to compare LiDAR and radiosonde winds. It was a collaborative test campaign between the University of Bergen, the Norwegian Meteorological Office (MET), Christian Michelsen Research (CMR) and Avinor. With the airports’ location at the Norwegian West Coast, additional motivations were the investigations in characteristics of coastal winds, as well as the validation of the LES turbulence forecast for the airport of Stavanger. We deployed two Windcubes v1 and a scanning Windcube 100S at two different sites in Sola, one next to the runway and the other one near to the autosonde from MET. The Windcube 100S scans several cross-sections of the ambient flow on hourly basis. In combination with wind profiles up to 200 m (Windcubes v1) and 3 km (Windcube 100S) and temporally more frequent radiosonde ascents, we collect a variety of wind information in the coastal atmospheric boundary layer.

  • Automated Surface Observing Systems (ASOS) IMPACTS
    Automated Surface Observing Systems (ASOS) IMPACTS Introduction The Automated Surface Observing Systems (ASOS) IMPACTS dataset consists of a variety of ground-based observations during the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) field campaign. IMPACTS was a three-year sequence of winter season deployments conducted to study snowstorms over the U.S Atlantic coast. IMPACTS aimed to (1) Provide observations critical to understanding the mechanisms of snowband formation, organization, and evolution; (2) Examine how the microphysical characteristics and likely growth mechanisms of snow particles vary across snowbands; and (3) Improve snowfall remote sensing interpretation and modeling to significantly advance prediction capabilities. This ASOS dataset consists of 176 stations within the IMPACTS domain. Each station provides observations of surface temperature, dew point, precipitation, wind direction, wind speed, wind gust, sea level pressure, and the observed weather code. The ASOS data are available from December 29, 2019 through February 29, 2020 in netCDF-4 format. Citation Brodzik, Stacy. 2020.

Most are currently airborne. 3 types of information can be obtained: a) Range to target (Topographic Lidar, or Laser Altimetry) b) Chemical properties of target (Differential Absorption Lidar) c) Velocity of target (Doppler Lidar) Focus on Laser Altimetry. Most active area today. 1 Lidar History 60s and 70s - First laser remote sensing instruments (lunar laser ranging, satellite laser ranging, oceanographic and atmospheric research) 80s - First laser altimetry systems (NASA Atmospheric and Oceanographic Lidar (AOL) and Airborne Topographic Mapper (ATM)) 1995 - First commercial airborne Lidar systems developed. Last 10 years - Significant development of commercial and non-commercial systems 1994 - SHOALS (US Army Corps of Engineers) 1996 - Mars Orbiter Laser Altimer (NASA MOLA-2) 1997 - Shuttle Laser Altimeter (NASA SLA) Early 2000s - North Carolina achieves statewide Lidar coverage (used for updating FEMA flood insurance maps) Statewide and regional consortiums being developed for the management and distribution of large volumes of Lidar data Currently 2 predominate issues - Standardization of data formats Standardization of processing techniques to extract useful information Comparison of Lidar and Radar Lidar Radar Uses optical signals (Near IR, Uses microwave signals. Wavelengths ≈ 1 visible). Wavelengths ≈ 1 um cm. (Approx 100,000 times longer than Near IR) Shorter wavelengths allow Target size limited by longer wavelength detection of smaller objects (cloud particles, aerosols) Focused beam and high frequency Beam width and antenna length limit permit high spatial resolution spatial resolution (10s of meters).
