Hi Michael,

Archived NLDN data is only available from Vaisala (sites including
SUNY Albany are explicitly prohibited from giving the archived data
to users outside of their campus).

However, since the UW/AOS department has been getting NLDN data for
quite a few years, there is a chance that they have their own archive
of the data.  I suggest you contact the LDM/IDD contact in AOS, Pete
Pokrandt, to explore this possibilty:

Pete Pokrandt <address@hidden>
608-262-3086

> Can I get it for free since it is for university research purposes?

If AOS does not have an archive, this is a question that only Vaisala
can answer.

> What years of data are available in the archive

Again, this is a question for either AOS or Vaisala.

> and what data format?

I would guess that the format of the archived data is the same or similar
to the format used in the NLDN IDD datastream.  This is described in our
Data->Lightning web page:

    Lightning
    http://www.unidata.ucar.edu/data/lightning_data_2.html
      NLDN Lightning Data
      http://www.unidata.ucar.edu/data/lightning.html#nldn

My guess about the format of the data archived by Vaisala could, of course,
be incorrect.  (We have never attempted to get archived data from Vaisala.)

> Thanks,

No worries.

Cheers,

Tom
