If it is free then beware. No cash, no liability.
I get data from Maquarie University but I pay for it. South Africa, Meteo France are good and reasonable. I also have an arrangement with NOAA.
A very famous old-established firm under the aegis of Company "B" will provide you with a tailored personal package for $45,000 per annum. Very reasonable in my view
Sadly the people who collect data want paying for it even, and dare I say it especially, in a certain UN organisation. So free, warrantied and trustworthy it ain't.
Try NOAA again, even in these "threatballs" days the person you speak to might be nice.
