Surface weather observations can include the following elements: The Station Identifier, or Location identifier, consists of four characters for METAR observations, [13] with the first representing the region of the world the station lies within. For example, the first letter for areas in and around the Pacific Ocean is P, and for Europe is E.
The following is an example METAR from Burgas Airport in Burgas, Bulgaria. It was taken on 4 February 2005 at 16:00 Coordinated Universal Time (UTC). METAR LBBG 041600Z 12012MPS 090V150 1400 R04/P1500N R22/P1500U +SN BKN022 OVC050 M04/M07 Q1020 NOSIG 8849//91= METAR indicates that the following is a standard hourly observation.
Airport observations can be transmitted worldwide through the use of the METAR observing code. Personal weather stations taking automated observations can transmit their data to the United States mesonet through the use of the Citizen Weather Observer Program (CWOP), or internationally through the Weather Underground Internet site.

This allows airport operations to continue using a valid TAF. In rare situations where observations have been missing for extended periods of time (i.e., more than one TAF cycle of 6 hours) and the total observation concept cannot provide sufficient information, the TAF may be suspended by the use of NIL TAF.

1960 – The first successful weather satellite, TIROS-1 (Television Infrared Observation Satellite), is launched on April 1 from Cape Canaveral, Florida by the National Aeronautics and Space Administration (NASA) with the participation of The US Army Signal Research and Development Lab, RCA, the US Weather Bureau, and the US Naval Photographic ...
An example of 500 mbar geopotential height prediction from a numerical weather prediction model. In the past, human forecasters were responsible for generating the weather forecast based upon available observations. [72] Today, human input is generally confined to choosing a model based on various parameters, such as model biases and ...

In this example the METAR indicates it is from EGXE (RAF Leeming) at 1150 UTC on Day 6. The observation follows (see METAR for explanation), with the Trend added to the end of the observation. The Trend reads TEMPO 6000 SHRA SCT020 WHT i.e. Temporary deterioration to 6 km visibility in a moderate rain shower with scattered at 2000 ft, colour ...
