Real-time Global Analysis and Prediction System Models (GLAPS)
Analyses
Description:
The Global Analysis and Prediction System, GLAPS, produces maps for several weather parameters over a large global domain. There are six GLAPS products available
for Science On a Sphere®. It is important for meteorologists to know the current conditions, not only in their local area, but also globally. A computer model is
used to create a first guess as to what the map should look like, and then observations are added to enhance the map. The observations come from Doppler radars,
satellites, wind and temperature profilers, radiometric profilers, as well as aircraft. GLAPS is such a powerful tool because of its ability to consolidate
observations from so many different sources. The GLAPS datasets are available in real-time, updating hourly, and include the data for the past week.
The one of the six GLAPS datasets is not real-time. It is a map of the fraction of the Earth that is green during the year. This dataset shows how the "green
fraction" changes during the year from January to December. Brown areas have no vegetation with greener areas representing vegetation. The other five GLAPS datasets
all update hourly. The first is a map of the ground and sea surface temperature in degrees Fahrenheit. The second map shows surface air temperature as an image with
surface air temperature contours and wind barbs overlaid. The third map is an image of the wind speed at 500mb in knots with wind barbs and 500mb height contours
overlaid. The fourth map is similar to the third, but is for the surface. It is an image of the wind speed in knots at the surface with wind barbs and the surface
pressure contours overlaid. The fifth map is an image of integrated water vapor (IWV) in centimeters. Colorbars for each of the datasets are below. Click the
