Course Description

ASOS Algorithms


Lesson Name
The Basic Process (from the ASOS Algorithms Tutorial Series)
   URL -> http://www.nwstc.noaa.gov/DATAACQ/d.ALGOR/d.BASIC/BASICalgoTitle.html
Note: ASOS is Automated Surface Observing System
Type of Lesson
WBT
Used primarily by meteorologists and hydrometeorological technicians
Description
ASOS uses data from a series of sensors to produce a METAR observation. Although each weather element in this observation uses its own set of algorithms to process information from one or more sensors, the basic process used by all elements is similar.
