Abstract
Abstract. Satellite measurements of surface wind speed over the ocean inform a wide
variety of scientific pursuits. While both active and passive microwave
sensors are traditionally used to detect surface wind speed over water
surfaces, measurements of reflected sunlight in the near-infrared made by the
Orbiting Carbon Observatory-2 (OCO-2) are also sensitive to the wind speed. In
this work, retrieved wind speeds from OCO-2 glint measurements are validated
against the Advanced Microwave Scanning Radiometer-2 (AMSR2). Both sensors are
in the international Afternoon Constellation (A-Train), allowing for a large number of
co-located observations. Several different OCO-2 retrieval algorithm
modifications are tested, with the most successful being a single-band
Cox–Munk-only model. Using this, we find excellent agreement between the two
sensors, with OCO-2 having a small mean bias against AMSR2 of
−0.22 m s−1, an RMSD of 0.75 m s−1, and a correlation coefficient of 0.94. Although OCO-2 is restricted to clear-sky measurements, potential benefits of its higher spatial resolution relative to microwave instruments include the study of coastal wind processes, which may be able to inform certain economic sectors.
