Interactive atmospheric pressure map. ICON and GFS models. Shows global forecasted mean sea-level pressure.
Latest forecast. 2 m temperature and 30 m wind. Air temperatures at 2 m above the earth's surface approximate most closely to the conditions a person would most likely experience... Latest forecast. 100 m wind and mean sea level pressure. These charts show surface pressure patterns.
This web app graphs the barometric pressure forecast and history of any location, along with relevant current weather data such as temperature, humidity and wind.
Global Sea Levels Graph. This graph features global sea level measurements from as far back as 800,000 years up to the present time with an atmospheric temperature overlay option. The graph is customizable and can be resized, printed, or pasted into your website.
This map displays the observed pressure at a given station adjusted to sea level for that station’s elevation using an algorithm. This algorithm corrects observed pressures at altitude to MSLP using standard atmosphere data that defines what the average pressure is at any given altitude.
Global maps of air pressure. The maps show the global distribution of the monthly means respectively the anomalies of the air pressure reduced to sea level. In areas with little data, especially over the oceans, there are hardly any measurements that allow direct analyses from observations.
This is in contrast to mean sea-level pressure, which involves the extrapolation of pressure to sea level for locations above or below sea level. The average pressure at mean sea level in the International Standard Atmosphere is 1,013.25 hPa, or 1 atmosphere (atm), or 29.92 inches of mercury.
