I am looking for in-situ measurements of wave heights for the Caspian Sea. I see that people published a comparison of wave modeling results with the in-situ data, so there are data from at least a few stations available, like Anzali, Neka, Amirabad, Fort-Shevchenko, Neftyanye Kamni, Kochubey, Astrakhan, Makhachkala, but simple googling does not show any downloadable data. Do you know where can I get the data, whom to ask and how open they are?
Many thanks!
