Model Cross Section - Basic Information

Figure 1. Example of the Model Cross Section product over the United States. The line on the inset picture in the upper-right corner depicts the location of the cross section.

1) Product Information:

- Who is developing and distributing this product?

The Cooperative Institute for Research in the Atmosphere (CIRA) in Fort Collins, Colorado, together with the NOAA/NESDIS RAMM Branch is developing and distributing the Blowing-Dust Product.

2) Product Description:

- Purpose of this product:

The cross section loops are being created to augment the loops of the synthetic satellite imagery. They provide a useful way to view the vertical distribution of atmospheric variables through features such as fronts and lee waves. Currently, potential temperature is the only quantity being displayed, but as the product develops, new variables will be added.

- Why is this a GOES-R Proving Ground Product?

The cross sections will be useful in the interpretation of the synthetic satellite imagery as they provide insight into the atmospheric processes occurring beneath the clouds which produce the patterns seen in the imagery.

- How is this product created now?

Every day at 00 UTC, NSSL runs their 4-km WRF-ARW. The output from the 9 hr to 36 hr forecast are used to create the cross section loops, which will typically be available at 0830 UTC. The location of the loop will be set at CIRA, generally corresponding to an area of active weather.
