Here is a graphic showing a breakdown of the plots.
- Exception is instead of altimeter (barometer) DA plots use
millibars, also
- a pressure measure. Normal is about 1016.0 mb - plots show last three
- digits 1016.0 = 160
- a pressure measure. Normal is about 1016.0 mb - plots show last three
Surface Data Plot
The surface data plot gives the following information:
| Data | Description |
| temperature (F) | plotted upper left |
| present weather | symbol plotted center left (see below) |
| dewpoint (F) | plotted lower left |
| pressure (.1 mb-coded) | plotted upper right as last 3 digits (987=998.7mb, 024=1002.4mb) |
| cloud cover | center circle. white fill indicates % cloud coverage (see below) |
| winds | wind barb (see below) |
