The form provides the opportunity to customized several important settings for visualization:

• MIN EXTENT : PODAAC SST grid points whose value is below this setting will render as 100% transparent.
• MAX EXTENT : PODAAC SST grid points whose value is above this setting will render as 100% transparent.
• POINT RADIUS : Adjust the radius (px) of track point markers
• LINES? : Toggle track line drawing mode off/on
• ICONS? : Toggle drifter/profiler icons off/on
• POINTS? : Toggle track point markers off/on
• LINE : Set color of Argo track lines (SPD trackline color is randomly set).
• DEEP : Set color of track point markers for Deep Argo profilers.
• BCG : Set color of track point markers for Biogeochemical Argo profilers.
• CORE : Set color of track point markers for Core Argo profilers.

PODAAC

Averaging SST over a longer period reduces the influence of clouds, which can be a good or bad thing. While you need SST values to render color, cloudy areas allow color from deeper SST layers in your work to blend with shallower layers.

You get the cool SST "textures" by layering several 8-day periods throughout the year, allowing you to blend color ranges and clouds everywhere.

Explore changes in SST and cloud patterns (weather)

Make mosaics of SST frames.

The more layers you add, the more you'll need to dial them (and their color) back to see Argo tracklines beneath.

Argo

Querying Argo data before SST data enhances the relation between Argo tracks, SST color features and currents.

Tracklines radiating from calibration points are interesting.

This art interface was developed using the Seaglass framework for network-based data visualization.
