The individual products are explained by accessing the More Info links. The GOES Sounder products are generated from 10 km spatial resolution data in 19 channels. The GOES Imager products are generated at 4 km spatial resolution and are displayed in 8 frame loops.
Products are composite images displayed on global maps covering the entire earth.
This Water Vapor Product was developed to help show instabilities that may be forming due to the upper air cooling or warming faster than the air beneath it. The GOES sounder receives radiances in nineteen different channels. The 7.43 m m channel brightness temperature changes are subtracted from those of the 7.02 m m channel creating the images displayed. Positive values are generated when there is warming on the 7.02 m m channel relative to the 7.43 m m channel, indicated by red colors. A general warming or drying at lower levels will be indicated by red colors, while a relative cooling at the lower level is indicated by blue colors.
