Another fine day in sunny Santa Barbara, light northerly winds at times.
The lidar was craned up on top of its container by Buck's Moving. It is in position but not powered yet.
Buck's also moved the ISS2 trailer from where it was dropped off at the Santa Barbara County HQ complex, over San Marcos pass along highway 154 to the Rancho Alegre scout camp site near Lake Cachuma. The Forest Service road up to the camp is a rough dirt road so we had Buck move it there rather than the truckers who brought the trailer from Boulder last week.
We started on setup of ISS2, unpacking and getting the profiler antenna into position and the clutter fence installed. We also started on the surface met tripod and on the power hookup.
Back at ISS1 late afternoon, I found that both the Modular Profiler distributed amp enclosure and the ISS1 container were getting rather warm, with the enclosure hitting 36C and the container reaching 33C. I turned down the duty cycle on the profiler (see below) although talking to John at dinner, he said that the amp enclosure should be okay at those temperatures. The container is more of a concern since it appears that the air conditioning in there has failed. I directed a fan at the computer rack to circulate air and hopefully keep the computers cooler. We will investigate further tomorrow.
On the Modular Profiler, I switched the operating parameters from a 5.3% duty cycle down to a 2.7% duty cycle. At 5.3%, the 50V power supply was reading 4.52A and the 32V supply was 1.864A. At 2.7% the supplies were 2.54A and 1.67A respectively. I toggled between both modes a couple of times 0130 - 0140 UTC (March 11). In both modes we seemed to be getting good signal up to about 2.6 km AGL.
