WXP is a software package developed at Purdue University in the Department of Earth and Atmospheric Sciences. It is intended to be an general purpose weather visualization tool for current and archived meteorological data. The products available with this server are derived from data obtained from the National Weather Service and the University of Wisconsin.

Current Data Observations

 Satellite imagery
This type of data comes from geostationary satellites orbitting around 22,000 miles above the equator. These satellites, commonly referred to as GOES satellites provide hemispheric shots of the earth on a hourly basis.

Surface data
Surface data comes from land based instrumentation generally setup at airports and reported on an hourly basis. This type of data are visualized in terms of simple plots on geographical maps, contours on the same maps and meteograms which are time series plots for a specific station. In addition, the National Weather Service provides locations of all fronts in North America which can be decoded and plotted.

Upper Air data
Upper air data aids in creating a model of the three dimensional structure of the atmosphere. The data are recorded by balloons sent up once every twelve hours (00Z and 12Z). These data are displayed as plots and contours as well as sounding plots.

Radar data
This data comes from meteorological radars placed at various locations across the United States. Each radar site reports a digitized assessment of the precipitation echoes displayed on the radar scope.

Current Forecast Model Data

 MOS Forecast
This document contains plots of MOS (Model Output Statistics) from both the NGM and MRF models. From the two models, gridpoint data are compiled and used to derive conditions specific to a particular city.

NGM Model Forecast (to 48 hours)
This directory contains contour plots of data from the NGM (Nested Grid forecast Model). This model gives forecast information out to 48 hours.

ETA Model Forecast (to 48 hours)
This directory contains contour plots of data from the ETA forecast model. This is a new model aimed at replacing the NGM model at some time in the future.

Aviation Model Forecast (to 72 hours)
This directory contains contour plots of data from the Aviation/MRF Model. This is a global model run by NMC whereas the NGM and ETA are regional models.

ECMWF Model Forecast (to 7 days)
This directory contains contour plots from the European Center for Medium range Weather Forecasting (ECMWF) forecast model.

Extended Range Forecast (to 10 days)
This directory contains contour plots from the Medium Range Forecast (MRF) model. The model output runs from observed data, every 12 hours to 10 days.
