All-Weather Tropospheric 3-D Wind From Microwave Sounders

In this paper, we describe a new approach to measure tropospheric wind vectors from space that has significant advantages over current methods and borders on a breakthrough capability.

Summary:In this paper, we describe a new approach to measure tropospheric wind vectors from space that has significant advantages over current methods and borders on a breakthrough capability. We report on the results of simulations of observations from a geostationary microwave sounder and, briefly, from a small cluster of low-earth-orbiting CubeSats. The geostationary simulations show a precision of better than 2 m/s for wind speed and 15° for direction. Wind speed bias is about -1 m/s. The transfer function is largely linear. Our studies show that this methodology will meet wind measurement requirements specified by the World Meteorological Organization.
