Introduction to Gridded Model Output Statistics (MOS)

Introduction

Objectives:

• Refresh trainees on how station-based MOS is made and its uses and limitations.
• Learn how gridded MOS downscales and how it differs from station-based MOS.
• Learn the situational capabilities and limitations of gridded MOS and the underlying basis for those capabilities and limitations.

Training Session Options

NOAA/NWS students – to begin the training, use the web-based video, YouTube video, or audio playback options below (if present for this session). Certificates of completion for NOAA/NWS employees can be obtained by accessing the session via the Commerce Learn Center

1. Audio playback (recommended for low-bandwidth users) – This is an audio playback version in the form of a downloadable VISITview and can be taken at anytime.

   Create a directory to download the audio playback file (41 MB) from the following link: http://rammb.cira.colostate.edu/training/visit/training_sessions/introduction_to_gridded_model_output_statistics_mos/introduction_to_gridded_model_output_statistics_mos_audio.exe

   After extracting the files into that directory click on either the visitplay.bat or visitauto.bat file to start the lesson. If both files are present, use visitauto.bat

2. VISITview playback without Audio – You may step through the VISITview file on your own to view the presentation. If talking points are available, you may use these in tandem with going through the slides.

   Create a directory to download the playback file from the following site: http://rammb.cira.colostate.edu/training/visit/training_sessions/introduction_to_gridded_model_output_statistics_mos/introduction_to_gridded_model_output_statistics_mos.exe

   After extracting the files into that directory click on the visitlocal.bat file to start the lesson. Advance slides on your own using the navigation controls (i.e., the Next button will advance to the next slide)
