Our focus in this project was providing guidance on the types of data that would be important for further process studies in the tropical Pacific region. There are three main types of data that would be important to have to help us further understand the atmosphere-ocean coupling and how accurately our models are representing this:
1. Direct flux observations are required, particularly in stable and low-wind and high-wind convective regimes, to clarify parameterization differences. The SPURS-2 dataset did not have many observations at these extremes, which is exactly where the largest differences among the flux paramaterizations occur.
2. Ocean observations of temperature and salinity with higher vertical resolution (<0.25m) in the upper few meters of the ocean. As shown by our model simulations, representing the depths where the heat and freshwater is has a strong impact on how stable the upper ocean is, and so how deep these properties get mixed down from the surface, which provides the link between the surface and the deeper ocean.
3. Atmospheric boundary layer profiles at high vertical (several meters) and horizontal resolution to understand surface-convection coupling, small-scale events such as cold pools. For understanding the ocean-cloud links, it is necessary to have a large number of events so that statistics of these events can be gathered and compared with the models.
