|ASOS-WX - MATLAB-based wind extraction software||
This is the download page for ASOS-WX, a MATLAB-based
software tool for the extraction of wind and thunderstorm data
from ASCII-format Automated Surface Observing System (ASOS) data
files, for use in extreme value analysis. Within the software,
one or more ASOS files can be selected for analysis, and the
software can then perform the following actions for all
The selected output results are written as comma-delimited text files (*.csv), which can be readily opened in standard spreadsheet software for further analysis and plotting.
The ASOS-WX software, along with documentation, is available for download at the links below. More information about ASOS itself can be found in the ASOS User's Guide from NOAA, and ASCII-format ASOS records can be obtained directly from NOAA, for a fee. To enable users to evaluate this software, a sample ASOS record is provided for download at the link below, which contains of 13 months of data from Newark International Airport and 39 months of data from New York LaGuardia Airport.
|Downloading Software and Sample Datasets|
|Create a Folder for All Files||It is recommended that users create a single folder named "ASOS-WX" on their local hard drive in which to save all downloaded files and folders.|
|Requires Version 7 of MATLAB Software||
The ASOS-WX software was developed and tested in
the Microsoft Windows environment using version 7 of MATLAB.
It is believed that the MATLAB m-files can be ported to
non-Windows (e.g., Linux/Unix) environments with minimal
changes. However, the software will not run under version 6
of MATLAB since it makes use of features that were introduced
with version 7.
If you do not have version 7 of MATLAB and you are running in the Windows 2000/XP environment, you can download and run the "stand-alone" file below. This contains a "compiled" version of the software.
In order to avoid individually downloading a large number
of files, we have provided the files in archive format
(i.e., only a single file has to be downloaded). Given
that users may be running on different platforms and that
some users may have firewalls that block the downloading
of certain types of files, we have provided several
alternatives for downloading.
Specifically, the following options are available:
