METAR indicates that the following is a standard hourly observation. KTTN is the ICAO identifier for the Trenton-Mercer Airport . 051853Z indicates the day of the month is the 5th and the time of day is 1853 Zulu/ UTC , or 1:53PM Eastern Standard Time .
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.
In weather forecasting, model output statistics (MOS) is a multiple linear regression technique in which predictands, often near-surface quantities (such as two-meter-above-ground-level air temperature, horizontal visibility, and wind direction, speed and gusts), are related statistically to one or more predictors.
Data dissemination is usually via an automated VHF airband radio frequency (108-137 MHz) at each airport, broadcasting the automated weather observation. This is often via the automatic terminal information service (ATIS). Most automated weather stations also have discrete phone numbers to retrieve real-time observations over the phone or ...
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
In the United Kingdom, when the observation is taken from an automated weather observation site, the shape is a triangle. [10] If the shape is completely filled in, it is overcast. If conditions are completely clear, the circle or triangle is empty.
SYNOP (surface synoptic observations) is a numerical code (called FM-12 by WMO) used for reporting weather observations made by staffed and automated weather stations. SYNOP reports are typically sent every six hours by Deutscher Wetterdienst on shortwave and low frequency using RTTY .
Furthermore, even what is reported in the main body of the METAR (the element containing something along the lines of 06/M02) is incorrect 2 times out of 15—for example, if the actual temperature were 41.72 °F, it gets measured as 42 °F and converted to 6 °C in the main body of the METAR, but actually 41.72 °F = 5.40 °C and should round ...
