I would like to know how good the weather data coverage is on the surface of the world’s oceans, and how much it would improve climate research/models if weather observations from ocean-going vessels were made publicly available. As I understand the current situation, publicly available ocean weather data is mostly measured via stationary floats and satellites, where the satellites only measure temperature.
Many ocean-going vessels measure sea temperature, air pressure + temperature and wind speed + direction. These vessels cover a fair bit of the ocean surface during their trips, and some vessels log these observations every hour or even more frequently.
I have two questions relating to this:
- Are there more publicly available sources of oceanic weather data than the ones I list in the beginning?
- Would weather data from ocean-going vessels be beneficial to climate research, by e.g. giving many additional calibration points for climate models relating to ocean weather? Can you give examples of which specific areas of research it would apply to? I’m thinking things like ocean heat absorption and emission, hurricane formation and maybe El Niño.
