The PO.DAAC is pleased to announce the public release of the Earth & Space Research, Ocean Surface Current Analyses Real-time (OSCAR) Level 4 Version 2.0 datasets. OSCAR ocean mixed layer velocities are calculated from satellite-sensed sea surface height gradients, ocean vector winds, and sea surface temperature gradients using a simplified physical model for geostrophy, Ekman, and thermal wind dynamics. More information regarding OSCAR is available from the Earth & Space Research website. Several enhancements over the previous release are implemented including:

• Increased spatial resolution of 0.25 degree
• Increased temporal resolution of 1 day
• Three quality levels of final, interim, and near real time with their respective latencies of 1 year, 1 month, and 2 days

Datasets comprising this release include:
