Model Forecast Comparison

NEAQS-ITCT 2004 Program Model Verification

We will compare model predictions with many of the special meteorological and chemical observations taken during ICARTT: NEAQS-ITCT 2004. These comparisons will be used to assess the fidelity of meteorological and chemical parameterizations within the models. The web site is organized as a cross matrix of the observation types and the models. Each model's 00 and 12 UTC 48 hour forecast is shown as soon as it becomes available, and the data are then added to the plots on an hourly basis as they become available. Ensemble chemical and meteorological forecasts are also displayed, formed as the mean of the various models contributing to ICARTT: NEAQS-ITCT 2004.

The observations fall into three major categories:

  1. Wind Profiler Sites - include the 7 ETL and AL land-based wind profilers, where displays of wind and temperature profiles as well as surface meteorology are shown. Surface ozone data is also shown, using data from the nearest AirNow locations.
  2. Chemistry Sites - include the AIRMAP locations, and include all major chemical variables measured.
  3. Mobile Sites - include the NOAA Ship Ronald H. Brown and the NOAA LIDAR aircraft. For both of these sites ozone lidar profiles are displayed. The Ronald H. Brown site also displays the on-board wind profiler and surface meteorology.
