Seefeld Cold-Air Pool Experiment (SEECAP): Meteorological Measurement Data

<p>The Seefeld Cold-Air Pool Experiment (SEECAP) focused on the cross-country skiing area Olympiaregion Seefeld and in particular the topographic setting in the Nordic ski arena which favors the formation of cold-air pools and took place between December 2019 and March 2020. Six automatic weather stations and 41 unventilated temperature sensors were distributed within the valley to gain insight into the spatial structure of the cold-air pool in Seefeld. The study site as well as locations and instrumentation of each station are described in Rudolph (2022) and Rauchöcker et al. (2024d). This upload contains meteorological measurement data associated with SEECAP. WRF simulations were performed for two nights, representing an ideal evolution of the cold-air pool (January 12 and January 13 2020) and a disrupted evolution (January 16 and January 17 2020), respectively. The output data of simulations with snow cover for the night between January 16 and January 17 2020 are published in Rauchöcker et al. (2024a) and in Rauchöcker et al. (2024c) for the night between January 12 and January 13 2020. Simulation output without snow cover is available for the night between January 16 and January 17 2020  in Rauchöcker et al. (2024b).</p> <h3><strong>Automatic Weather Stations</strong></h3> <p>Measurement data of the six automatic weather stations can be found in <em>momaa.zip</em>. The folder includes one file for each station (<em>MOMAA02.dat, MOMAA03.dat, MOMAA04.dat, MOMAA07.dat, MOMAA08.dat</em> and <em>MOMAA10.dat</em>). These stations measured temperature, pressure, humidity, net radiation, wind speed and wind direction at 1-min intervals. A figure showing the location of the different stations is included as well (<em>Stations.pdf</em>); the station names of the automatic weather stations are abreviated in the legend of that figure (e.g. M04 instead of MOMAA04). Incoming and outgoing longwave and shortwave radiation, latent heat flux and sensible heat flux were measured at MOMAA04 and MOMAA08. The radiation data can be found in <em>MOMAA04_rad.dat</em> and <em>MOMAA08_rad.dat</em> and eddy covariance data in <em>MOMAA04_turb.csv</em> and <em>MOMAA08_turb.csv</em>, respectively.</p> <h3><strong>Temperature Sensors</strong></h3> <p>Data from the unventilated temperature sensors can be found in <em>hobos.zip</em>, which contains a file for each sensor and the file names refer to the naming convention in <em>Stations.pdf</em>. Most sensors were located along the valley floor and along a ski jump on its southeastern slope. At nine locations, temperature sensors were mounted at two heights (1 m and 2 m above the ground). File names reflect that height by adding <em>_1m</em> or <em>_2m</em> to the file name (e.g. <em>A_1m.txt</em> and  <em>A_2m</em>.txt). Locations that had only one sensor were named according to the station name (e.g. <em>M.txt</em>). The remaining sensors were used for vertical profiles at 3 different levels of a walk-up tower (<em>TOWER_2m.txt, TOWER_2ndfloor.txt</em> and <em>TOWER_top.txt</em>) and at a bridge (VP; labeled from <em>VP_050.txt</em> at 0.5m above the ground to <em>VP_630.txt</em> at 6.3m). A pseudo-vertical profile for the sensors along the slope of the valley, at the walk-up tower down to the lowest station in the upper basin (top to bottom, M03, S4, S3, S2, S1, M10, G, H, M04) can be found in <em>PseudoProfile_basin.mat</em>. </p>

Numerical study on advective fog formation and its characteristic associated with cold water upwelling

<p>Recent rapid industrial development in the Korean Peninsula has increased the impacts of meteorological disasters on marine and coastal environments. In particular, marine fog driven by summer cold water masses can inhibit transport and aviation; yet a lack of observational data hinders our understanding. The present study aimed to analyze the differences in cold water mass formation according to sea surface temperature (SST) resolution and its effects on the occurrence and distribution of sea fog over the Korean Peninsula from June 23–July 1, 2016, according to the Weather Research and Forecasting model. Data from the Final Operational Model Global Tropospheric Analyses were provided at 1° and 0.25° resolutions and NOAA real-time global SST (RTG-SST) data were provided at 0.083°. While conventional analyses have used initial SST distributions throughout the entire simulation period, small-scale, rapidly developing oceanic phenomena (e.g., cold water masses) lasting for several days act as an important mediating factor between the lower atmosphere and sea. RTG-SST was successful at identifying fog presence and maintained the most extensive horizontal distribution of cold water masses. In addition, it was confirmed that the difference in SST resolution led to varying sizes and strengths of the warm pools that provided water vapor from the open sea area to the atmosphere. On examining the horizontal water vapor transport and the vertical structure of the generated sea fog using the RTG-SST, water vapors were found to be continuously introduced by the southwesterly winds from June 29 to 30, creating a fog event throughout June 30. Accordingly, high-resolution SST data must be input into numerical models whenever possible. It is expected that the findings of this study can contribute to the reduction of ship accidents via the accurate simulation of sea fog.</p>
