MAG Help


The Model Analysis and Guidance website displays GIF (Graphical Interchange Format) images of the output of NCEP’s weather prediction models; observational data in the form of SKEW-T and station plots; output from the Real Time Data Analysis model and hurricane model information when storms are active. The application runs in two environments:

  1. The Weather and Climate Operational Supercomputer System (WCOSS) to consume gridded model data and produce images.
  2. A public facing Web Server farm where web navigation code provides an organized interface to the data and a set of bookmark able URLs that customers can use to directly access the latest images.
