I might be of some help to you in finding a sustainable business model.
For about a week now, I've been at home in Santa Barbara in the cross hairs downwind of a very large wildfire. If there is a blessing in this, It's that it led me to windy.com, for reasons you can imagine.
I saw your posts and a few others on the business model quest and have a few sustainable directions to offer (with a fun backstory as to how the idea presented itself).
Here's my profile . What's not there is the surfing, sailing, hang gliding stuff... so I'm also personally blown away by the project.

Hi, Sorry but still I am not able to understand how can I access historical data? Please can anyone help about same... Also how I can get forecast data? how I have to pay for same? what will be format of data? Can i get data in csv/netcdf/text format?
Also you can contact me on company email id "firstname.lastname@example.org" as we want this data for solar energy forecasting in India as well as outside. So we can purchase forecast data as well as acknowledge you as a valued weather data providers for us...
Hoping positive reply...Thank You

Is it possible to get historical data from the Chernobyl disaster (25. April 1986 to 28. April 1986)?
I have a project about the Chernobyl disaster. Showing the wind animation from the date will help me a lot.
If there's historical data from the Chernobyl disaster, that I can have access to, please send a message to me on:
where you can see radioactive cloud driven by prevailing winds.

Thank for the help. But do you know a website where I can see a wind animation of the Chernobyl disaster?
The ones you've sent is the radioactivity that has spread all over Europe, but I would also like to get a map over the wind, such as Windy.com's design
Here you can find some archived data.
Note: I sent you the "radioactivity animation" as it takes into account many wind fields (for many days and in many levels).

What a pity！I would like to have accessed some historical data for my PowerPoint about meteorology. Well, I will still support Windy.

I need a data for the last year for my location, I need data for wind speed for every hour. where can I found it?
my location is Hengelo, Overijssel, Netherland.
Or can you send it to me?
this is my email email@example.com
If you are interested in official data, you have to contact:
As I can see, nearby there is the Twenthe Airport.
At the airport (location indicator EHTW) there is a meteorological station
and (I believe) people there can provide you data needed.
Also you can search the internet for actual weather data for met. station
Twenthe Airport, EHTW in various sites
Also, you can download the data from Twenthe Automatic Weather Station, here

Could you give us an idea of how much space 1 month of data would take?

Re: storage. Access even to a very sub-sampled historical data would be useful as well!
If you have data at 1 degree resolution, that is roughly 360*180 points per globe. If you were to only keep 5 (7, 10) basic measurements (pressure, temperaturue, wind speed/direction, precipitation) at three different altitudes (0, 850hPa, 500hPa), it gives you: 360 * 180 * 5 * 3 * 4 (bytes per float32), which is about 4MB per measurement. Sample it every 3 hours over a year, and that would be 8GB/year. Go to 0.5 degree resolution, and that's 32GB/year. That still can fit on my laptop. And I think grib files actually use less than 4 bytes per point.
I was also frustrated with the lack of any ways to access historical data. So I'm actually planning to download a bunch of grib files from public GFS server, select only relevant timepoints/layers, and save them for viewing in existing grib viewers (or publish them somewhere). It is still a lot of work, probably a week of coding for me, and however many days/weeks to download the data. I may actually do this project at some point.

Is it possible to view data less than 24 hours ago?
I assumed this was possible, but there is a reset at 00:00.
