Warning: These data are experimental, and are not
always accurate. We update incorrect METAR locations based in part on
user input. So, if you notice a misplaced station
please notify
us. If you notice a
station that appears to be producing erroneous data, please notify the
ASOS Operations and Monitoring Center
(AOMC)
Drag (move the mouse while holding
down button 1) to choose an area in which to zoom. (The zoom
will occur as soon as the mouse button is released.) You can also
zoom and roam by using the
overview
window. Undo zooming and roaming by clicking the un-zoom
or reset
button.
Choose to display weather information, counties and/or rivers by clicking the appropriate buttons. (Image rendering is faster when fewer lines are displayed, so you may wish to only display these after you have zoomed in.)
Click on a station to display its raw METAR report in a separate window.
Click on the color bar to hide all data except those corresponding to the color you have selected. The other colors will be x-ed out on the color bar. Or, click and drag on the color bar to show only a range of data. Click on any non-x-ed out color on the color bar to show all data again. (I think the colors are terrible. If you have a better color table, please send it to me.)
The Refresh button reads new data. The data files are created at the top of each hour and contain METARs having observation times within a time window from 15 minutes before the hour, to 44 minutes after the hour. This file is updated at 5, 10, 15, 20, 25, 30, and 45 minutes after the hour. More information.
