The UTD crew arrived at the BAO site last Tuesday, March 3. The UDT 200S was already deployed at the visitor center (Thanks Alan, Adytia and Scott for your help!!!). After a preliminary check, the lidar was powered up and controlled through a local computer. The main issue encountered is the short range of the measurements. We are working with Leosphere to plan an intervention to install a new EDFA and circulator, although they already installed the same components brand new only 5 weeks ago!
The UTD 200S was connected to the NOAA local computer and remotely operated via TeamViewer. The connections resulted to be very slow, which implied long sessions for test programming. For the preliminary tests, fixed measurements at low elevation angles were performed since Wednesday, March 4, 7 pm till Thurday March 5, 6 am. A Diary of the experiment has been setup on a Google doc. Please send your email address if you want access this document.
On Thursday March 5, the locations of the 12 sonic anemometers on the met-tower were detected with the lidar. Fixed measurements were performed by staring the lidar for about 1h in front of each sonic anemometer. This test was performed simultaneously with the lidar Dalek 1. However, Dalek 1 experienced some issues with the GUI, thus most probably the full data set is not available for the intercomparison.
On Friday March 6, 7 am, the UTD 200S was deployed at the NE concrete pad (Thanks to all crew Adytia, Jim, Julie, Scott, and more; full credits to Alan who was able with the truck to came out from the melted snow!) . We were not able to start up the lidar in the new location for a while. With Bruce we checked the power supply, which was compliant with the specs. Then with Alan and Scott, we realized that with a manual reset on the internal computer, the lidar was back again. Thus, we have A NEW FEATURE for the 200S!!! We were able to detect the tower and the sonic locations. We worked on the focus, and yesterday we were able to achieve a range of 1.5 km with a resolution of 25 m, and about 2.5 km for a resolution of 75 m. We set 50 min fixed measurements over the 12 sonic anemometers, all the details are reported in the Google docs. These scans will run daily.
We are currently working in the setup of a laptop + 3G modem for remote control and data transfer.
Thank you all for the great learning experience.
