jackdale Thanks Adam

Any tsunami out there? Last I heard was .4 - .6 meters forecast on the west side, but a concern for current.

Copprhead I'm trying to find a tool to convert v2 to the "legacy" GRIB format and/or use it with the JGRIB library. Then I could write some code that calculates averages of all this data to give wind info similar to that on pilot charts.

If anybody has experience working with these files, please let me know.

.grb file format

As I mentioned, these are GRIB v2 files. Some software isn't capable of viewing GRIB2, just check your documentation.

I have opened and tested the files though, and they are valid GRIB files.

For example, here's a screenshot from Jan 5 1990 around New Zealand showing valid data.

Copprhead Thank you smcauliffe and DivaNZ620 for sharing.
Any chance we can get 2000-2009 as well?
I could make this available for download via HTTP if there is a need.

smcauliffe Hi,

DivaNZ620 very kindly sent me the data he has.

The data contains global wind vectors for 1990-1999, non-aggregated. Unfortunately no other data like wave height, etc., but still useful.

The files are GRIB v2, so may not work with some software that only supports v1.

I have temporarily posted a bittorrent stream of the data at:
simonmcauliffe.com/downloads/Global_Wind_1990-1999_GRIB.torrent

This download is intentionally bandwidth limited, but if a bunch of people download it simultaneously, it should speed things up. So go for it!

I will look at putting the data up somewhere more convenient if there is demand for it or if bittorrent is too bit a problem.

I believe this data is originally sourced from NOAA.

Copprhead The NG/GRIB charts sound very interesting. Any updates on their availability for download?
