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).
Sea Level Pressure
The sea level pressure is the atmospheric pressure at sea level at a given location. When observed at a reporting station that is not at sea level (nearly all stations), it is a correction of the station pressure to sea level.
Sea Level Pressure - the atmospheric pressure computed from the station pressure for the given elevation of the station above mean sea level ...
Sea Level Pressure The pressure value obtained by the theoretical reduction or increase of barometric pressure to sea-level.
SEA LEVEL PRESSURE
The atmospheric pressure at mean sea level, usually determined from the observed station pressure.
SEA MILE
A unit of length distinguished from a nautical mile. One sea mile is equivalent to 1,000 fathoms (6,000 feet).
Sea level pressure The atmospheric pressure at mean sea level.
Secondary air pollutants Pollutants that form when a chemical reaction occurs between a primary air pollutant and some other component of air.
Sea level pressure The atmospheric pressure at mean sea level.

Sensible heat transfer Movement of heat from one place to another as a consequence of conduction or convection or both.
sea level pressure—The atmospheric pressure at mean sea level, either directly measured by stations at sea level or empirically determined from the station pressure and temperature by stations not at sea level; ...
Mean sea level pressure (MSLP or SLP) is the pressure at sea level or (when measured at a given height on land) the station pressure reduced to sea level by an appropriate altitude dependant formula.
Lowest sea level pressure recorded. 870 mb. 25.70" Typhoon Tip. Oct. 1979.

In this way, a Mean Sea Level Pressure (MSLP) map will then show pressures affected by changing weather conditions, not because of changing altitude.

A trough on a mean sea level pressure chart, (or an upper air contour chart) can be picked out by an arrangement of isobars (contours) which are concave towards an area of low pressure (low contour height) along a particular axis, ...
The total amount of ozone in the atmosphere would correspond to less than 1 part per million if uniformly distributed, or a column amount of about 3 mm if compressed to sea level pressure.
Aleutian low - The low pressure center located near the Aleutian Islands on mean charts of sea level pressure. It represents one of the main centers of action in the atmospheric circulation of the Northern Hemisphere.
NAO Index - This index measures the anomalies in sea level pressure between the Icelandic low pressure system and the Azores high pressure system.
FAHRENHEIT: A temperature scale having the freezing point of pure water at 32° and the boiling point at 212° under standard sea level pressure.
FIRMWARE: Programs or instructions which are stored in read-only memory.
The atmospheric pressure at the center of a high or low. It is the highest pressure in a high and the lowest pressure in a low, referring to the sea level pressure of the system on a surface chart.
CENTRIFUGAL FORCE ...
CENTRAL PRESSURE The atmospheric pressure at the center of a high or low. It is the highest pressure in a high and the lowest pressure in a low, referring to the sea level pressure of the system on a surface chart.
ALTIMETER An instrument used to determine the altitude of an object with respect to a fixed level. The type normally used by meteorologists measures the altitude with respect to sea level pressure.
