Local Modeling at NOAA/NWS Marquette
Incorporating TAMDAR Data

Model Configuration

• Local Analysis Prediction System (LAPS version
  0-24-3) used for hourly data assimilation/analyses
  
• LAPS cycles each hour with the WRF-ARW (version
  2.0.3.1), providing WRF with its initial
  conditions and using the WRF forecast as its
  (LAPS) first guess
• LAPS is ingesting a combination of MADIS and
  AWIPS data comprising all basic data (METAR,
  maritime, mesonet, RAOBs, profiler, satellite
  imager, aircraft w/TAMDAR, etc)
• LAPS is not currently running in diabatic hot
  start mode due to technical problems, but a
  solution to this problem is being sought

Model Configuration

• LAPS utilizing 22 vertical levels with 15km grid
  spacing
• WRF-ARW utilizing 31 vertical levels with
  identical grid spacing (15 km) and domain
• Model top at 50 mb
• Kain-Fritsch (new) cumulus scheme
• Lin et al. 5 class microphysics scheme
• RRTM longwave radiation scheme
• Goddard shortwave radiation scheme
• Noah land surface model
• YSU PBL scheme

Access to Model Output

• Model output is available via the web
• Internally (within NWS), the output is available
  at
• http//wseta.mqt.noaa.gov/SOO/wrf_html/wrf.php
• The output is available to anyone at
• http//www.crh.noaa.gov/mqt/data/wrf_html/wrf.php
• Display of static images and loops (one hour
  temporal resolution) is available
• Basic diagnostic fields are available as well as
  a few aviation parameters
• Soundings are available for a number of locations
  in Wisconsin and Upper Michigan (if you would
  like a sounding generated for another site,
  contact thomas.hultquist_at_noaa.gov)

Archive Efforts

• A 14 day running archive is maintained for raw
  data files and web-based model output
• Data is permanently archived for cases of
  interest
• Thus far, two cases have been archived (a lake
  effect snow event and a heavy rain event)
• Forecasters (and other SOOs) are encouraged to
  contact thomas.hultquist_at_noaa.gov with
  interesting cases so that they can be permanently
  archived for later study
• Model simulations with/without TAMDAR data will
  be conducted on archived cases of interest
• Information on the project and results from a few
  case studies will likely be presented at the
  U.S./Canada Great Lakes Operational Meteorology
  Workshop scheduled to take place in Grand Rapids,
  Michigan, September 14-16, 2005.
