High Rate ISFF data for HVAMS03
The full HVAMS03 dataset is archived in binary files, which contain the raw,
uncalibrated sensor output. The HVAMS03 high-rate archive files
are available by FTP (soon), on DVD, or from the
A Java application, which calibrates this sensor output into ASCII or NetCDF
form, is available for download.
Using this application you can write variables for time periods of
interest into text or NetCDF files for further processing using
any analysis software you choose.
Therefore, in order to generate high rate ISFF data, you must do the
following. Further information on these steps is contained in
the table of contents, to the left.
The binary data files were archived in a directory called "all".
The java application expects to find the files in a directory with that name,
so when copying or downloading the files to your system, put them
in a directory called all.
- Install Java on your system. It must be at least version 1.3. You can
install either the JRE (Java Runtime Environment) or the Java Developers Kit,
which is variously known as the JDK, the SDK or the J2SE.
- Download and install the ISFF java application.
- Get your hands on the appropriate binary archive files, by FTP, DVD,
or direct transfer from the NCAR mass store.
- Run the ISFF java application.
The file names have the following format: sN_yymmdd_HHMMSS.dat
where N is the station number (1-9). yymmdd_HHMMSS are the
the two digit year, month, day, hour, minute and second fields,
representing the start time of the data in the file, in GMT.
Each file contains up to 24 hours of data, usually starting at 00:00:00
GMT of the day. One day's data from a station is about 20 Mbyte.
The size of the entire dataset for the project is 9.3 Gbyte.
The high rate data can be copied to DVD+R disks, which
can be shipped to investigators on request.
If you have direct access to the
the binary files are archived
Use the msrcp command from a UNIX system to copy files from the
For example, to copy all files for October 26th to your hard disk:
You must use quotes around the name of the mass store file
mask, and note the trailing period (after a space). Also note the
files were placed in an all directory. In
this case you would set RAWDATADIR to /some_data_directory (see
section on Running Java App).
msrcp 'mss:/ATD/DATA/2003/HVAMS03/isff/raw_data/all/*031026*' .
