NOTE: We've guessed that you're not using a client that supports colored tables and have tried to compensate. Low graphics mode looks much better on clients that do... we recommend switching to Netscape 3.0 or Microsoft Internet Explorer.

Observed Sea Level Pressure
station reporting symbol

The value highlighted in yellow located in the upper right corner (in the diagram above) represents the last three digits of the observed pressure reading in millibars (mb).


Interpreting Pressure Reports:
If reported value greater than 500:
Initial 9 is missing. Place it on left, then divide by 10.
For example: 827 becomes 982.7 mb.

If reported value less than 500:
Initial 10 is missing. Place it on left, then divide by 10.
For example (as in above diagram): 027 becomes 1002.7 mb.
