HVAMS03 ISFF 1-minute ASCII Data Access

The ISFF HVAMS03 1-minute dataset contains means of all sampled variables.

Status of Dataset

Initial Release, February 4, 2005

1-min average values of measured parameters in NetCDF and ASCII form, for somewhat higher time resolution of events. These data have been processed using some of the steps described in the HVAMS03 project report. The variables Tsfc.trh and Tsfc.ad are superceded by the variable Tsfc and should be ignored.

Java Applet and Plugin

Downloading ASCII data (.txt) uses a Java applet for selecting variables and time periods. Your browser must have support for (at least) Java version 1.2 to run the applet. If your browser does not have support for Java 1.2, you should be redirected to a web site where you can download a plug-in for Netscape, Mozilla or Internet Explorer. The plug-in is available for Linux, Solaris and Windows.

Version 1.2 of Mozilla will not redirect you to the plug-in download page if the plug-in is needed. You must click on the java.sun.com link, below to get the plugin.

Java Plug-in Information

Netscape/Mozilla users can enter a URL of about:plugins, or click on Help->About Plug-ins to display the plug-ins which have been installed.

The current Java run-time environment (JRE) which includes the Java plugin for Windows (IE/Netscape/Mozilla), Linux (Netscape/Mozilla) and Solaris (Netscape/Mozilla) is available at http://java.sun.com/j2se/1.4.2/download.html.

If that link is broken, try http://java.sun.com/j2se.

Download the JRE (Java Runtime Enviromment) from the latest version of the J2SE. You don't need the extra stuff, like NetBeans.

Installation instructions are available at http://java.sun.com/j2se/1.4.2/jre/install.html.

Some Notes about the Java plugin on Various Platforms

  1. Mozilla and Linux
  2. Netscape and Linux

Java Applet User Interface

The data selection applet provides four areas for user input.
  • A "Times" section for selecting the start and end times of your request, in Eastern Daylight/Standard Time, EST5EDT (4/5 hours earlier than GMT).
  • A "Variables" section for selecting the variables of interest. The variables are grouped under folder tabs by station name, height, and (loosely) by variable type.
  • An "Output Format" section for choosing the format of the ASCII output
  • A Download button. The browser will popup a file selection menu where you can enter the desired file name.
