Abstract
The first Doppler Wind and Temperature Sensor (DWTS) using the Doppler Scanning with a Gas Filter (DSGF) measurement technique has been constructed. It is now ready for performance testing in a Virginia Tech Laboratory. The DSGF approach promises extraordinary signal-to-noise and spatial resolution by simultaneously modulating the emission from an entire spectral band. The modulation is measured over typically 100 seconds without affecting spatial resolution. The port or starboard measurement resolution is characteristic of an Earth limb imager: 2km in the vertical (potentially continuous from 20 to 250 km), 10 km along-track and 150 km in the observed limb direction.
