TTUKa Radar Update

We had fairly decent clear air signal today and were able to collect approximately 4.25 hours of dual-Doppler data. We began scanning at 18:20 UTC and acquired 30 minutes of virtual towers (at the RHI intersection offset from the lidar supersite) using a faster scan speed to increase temporal resolution. The scan speed was then reduced to allow for better data quality. We collected 3 hours of virtual tower data with the slower scan speed. With the reduced scan speed, data quality were very good. Only a few time periods contained noise at the dual-Doppler intersection point. Dual-Doppler sectors over the BAO site comprised the last 30 minutes of the deployment, but second trip echoes and degrading data quality will probably limit the usefulness of some of that time period.

We expect conditions to be similar tomorrow, and will target another clear air deployment. Todays scanning brings the total number of minutes scanned to 5501 of the available 7200.
